EPA Review Keeps Bee-Toxic Pesticide Sulfoxaflor on the Market with Limited Restrictions

(Beyond Pesticides, October 17, 2016) The U.S. Environmental Protection Agency (EPA) revealed its plan last Friday to register the toxic chemical sulfoxaflor, in the face of  overwhelming evidence that it negatively affects bee populations. This decision is the final result of a long-fought legal battle over the chemical’s registration, spearheaded by beekeepers and public health organizations concerned with what has been identified as EPA’s inadequate and flawed pesticide review processes. The agency claims that amendments made to the original registration, such as reducing the number  of crops for which use is permitted or only allowing post-bloom applications, will protect pollinators. However, scientific studies have shown that there is no way to fully limit exposure to bees, especially native species that exist naturally in the environment, given that the chemical, being systemic, is found in pollen, nectar, and guttation droplets. Given the evidence of harm related to sulfoxaflor’s use, as well as its demonstrated lack of need, advocates maintain that the agency’s decision to issue an amended registration violates its  duty to protect human health and the environment. Sulfoxaflor’s initial 2013 registration was challenged by beekeepers and subsequently vacated by the Ninth Circuit Court of Appeals due to overwhelming risks to […]

California Regulators Allow an Increase in Toxic Fumigant Use, Failing to Protect Public and Farmworker Health

(Beyond Pesticides, October 13, 2016) Last week, the California Department of Pesticide Regulation (CDPR) released new rules that allow for continued use of the toxic fumigant Telone and reduce public health protection by permitting increased usage. One of the active ingredients in the product Telone,  1,3-Dicholorpropene (1,3-D), has many documented health risks, including cancer and kidney and liver damage. While CDPR and many news outlets reported the rule change as a tightening of the restrictions, the new rules effectively increase the previous annual cap from 90,250 pounds to 136,000 pounds per township, a defined area of 6×6 miles. According to CDPR documents, the primary revisions include: increasing the annual limit to 136,000 pounds within each pesticide township, eliminating “rollover” of unused pesticide allotments from prior years, and banning use of Telone in December, when weather conditions are especially problematic for air pollution. These new rules, which go into effect January 1, will allow for 1,3-D’s continued use in strawberry fields, vineyards, almond orchards, and other crops around California. CDPR has been characterizing  its changes in management of 1,3-D as increasingly protective of public health in the state. In making these revisions to the rules, CDPR completed an updated risk assessment […]

In Bayer-Monsanto Merger, Bayer Pledges Not to Push GE Crops on Europe

(Beyond Pesticides, October 12, 2016) German chemical company Bayer said it would not introduce genetically engineered (GE) crops in Europe after its historic takeover of U.S. seed and pesticide producer Monsanto. The European Union (EU) has been skeptical of GE crops, with many countries refusing to approve certain varieties of them. However, in the U.S., where GE crops make up about half of the crops grown, the merger will probably have little to no effect on GE use. Last month, St. Louis-based agrichemical giant  Monsanto Co. agreed to sell the company  to German pharmaceutical and chemical conglomerate, Bayer, in  an unprecedented $66 billion dollar deal. This takeover of the U.S. firm is the biggest ever by a German company. The combination would create a global agricultural and chemical giant ””and bring Bayer together with a leading producer of genetically engineered seeds that are engineered to resist pesticides, particularly Monsanto’s flagship product, Roundup. Roundup, whose active ingredient is glyphosate, is used alongside various GE crops including corn and soybeans. In 2015, the World Health Organization’s International Agency for Research on Cancer (IARC) released a landmark  report naming glyphosate as  “probably carcinogenic to humans.” Glyphosate’s EU license was set to expire this […]

U.S. House Committee Wages War on Finding that Monsanto’s Glyphosate (Roundup) Causes Cancer

(Beyond Pesticides, October 11, 2016) Last week, in a calculated attack on the International Agency for Research on Cancer’s (IARC), the U.S. House of Representatives’ Committee on Oversight and Government Reform summoned the National Institutes of Health (NIH) to answer questions about taxpayer contributions to the World Health Organization’s (WHO) cancer agency. From reports, it is easy to gather that the committee has problems with IARC scientists’ findings that glyphosate, among other things, is a probable  carcinogen. Led by Chairman Jason Chaffetz (R-UT), the hearing is  clearly aimed at  undermining IARC’s March 2015 listing of glyphosate as a probable carcinogen based on sufficient evidence of carcinogenicity  found in laboratory studies. Set to take place in private, limiting any opportunity for public oversight, the hearing will consist of NIH officials answering questions on the scientific processes and public funding from politically-charged committee investigators. If Rep. Chaffetz is persuasive in this rouse against science, he stands to put in jeopardy  a significant amount funding for IARC provided by NIH, a devastating outcome for individuals who value the importance of IARC’s work in the scientific community. Glyphosate, which is produced and sold as RoundupTM  by Monsanto, has been touted by industry and EPA […]

Former Undisclosed Ingredients in Pesticide Products Found in Fish, Birds, and Dolphins

(Beyond Pesticides, October 4, 2016) Chemicals previously used as  inert ingredients in pesticide formulations have been detected in a wide range of North American wildlife species, according to research published in the journal Environmental Science and Technology. The compounds, perfluroalkyl phosphinic acids (PFPIAs), were widely used as anti-foaming agents in pesticide formulations until 2006, when the U.S. Environmental Protection Agency took regulatory action to cancel  their use, citing “human health and environmental risks of concern.” However, the chemicals continue to be used today in consumer goods, including carpet cleaning formulas. While scientists did not find what they would consider high concentrations of the chemicals in wildlife, the ubiquity of the detections was found to be most concerning. Researchers detected the presence of PFPIAs in the blood of 100% of animals sampled. This includes northern pike in Montreal, Canada, cormorants from the Great Lakes, and bottlenose dolphins from Sarasota Bay, Florida. “We aimed for diversity: air-breathing versus water-breathing, differences in habitat, different taxonomic groups,” Amila O. De Silva, PhD, coauthor of the study, said to CNN. Part of the reason for the wide range of detection lies with the properties of these chemicals. They are highly stable and resist degradation from […]

EPA Fines Syngenta $1.2 Million for Multiple Safety Violations under Settlement

(Beyond Pesticides, September 27, 2016)  Multinational pesticide manufacturer Syngenta Crop Protection was handed a  $1.2 million fine last week for multiple violations of federal pesticide law, according a settlement reached with the U.S. Environmental Protection Agency (EPA). EPA charged Syngenta with three major violations of the Federal Insecticide Fungicide and Rodenticide Act (FIFRA), including: (1) Failure to have repackaging agreement and/or maintain records on registered pesticides; (2) Distributing misbranded pesticides, and; (3) Failure to maintain data submitted for pesticide registration. However, under the consent agreement reached with EPA, the company neither admits nor denies the allegations. The settlement comes at a time of increased scrutiny of Syngenta, as the company is in the process of reregistering the herbicide atrazine, and Chinese National Chemical Corporation (ChemChina) continues its attempts to complete a $43 billion merger. While the plan appears to have cleared U.S. regulatory hurdles, European lawmakers have yet to sign off on the deal. “The repackaging, sale and distribution of unregistered and misbranded pesticides is illegal and puts people and the environment at risk. Users rely on accurate, up-to-date information about ingredients, directions for use, hazards and safety precautions,” said Anne Heard, Acting Regional Administrator for the Southeast in an […]

Public Health Watchdog Sues Dow Chemical in California Over Air Pollution Caused by Toxic Pesticide

(Beyond Pesticides September 26, 2016) Last week, the Center for Environmental Health (CEH) filed a lawsuit against Dow Agrosciences LLC, also known as Dow Chemical, charging  that the “chemical manufacturing giant” fails to warn communities across California about the dangers associated with wide use of the chemical Telone. A trade name for the chemical 1,3-Dicholoropropene, or 1,3-D, Telone is a known carcinogen and is the third most heavily used pesticide in the state. The case focuses on the air pollution caused by the pesticide, as it has been found to linger in the air for multiple days after application, disproportionately impacting the rural communities, often with large minority populations, that live in the immediate vicinity. The case was filed in the State of California Alameda County Superior Court, and Dow has yet to comment or release a statement addressing the allegations against the company. Routinely applied to strawberry fields, almond orchards, vineyards, and an array of other crops, 1,3-D is a restricted use soil  fumigant, used to kill nematodes, insects, and weeds that has strong links  to cancer and other serious health issues. The use of the chemical in the production of strawberries came into prominence with the forced reduction […]

United Nations Addresses the Alarming Rise of Antibiotic Resistance

(Beyond Pesticides, September 22, 2016) Yesterday, the United Nations (UN) gathered to address the alarming rise of antibiotic resistance at a day-long meeting in New York. The UN General Assembly, made up of delegates from 193 countries, has only convened health-related meetings on three other issues: Ebola, HIV, and noncommunicable diseases. According to the World Health Organization, which collaborates with the UN on health-related priorities, “Antimicrobial resistance has become one of the biggest threats to global health, such as human development.” At this high-profile meeting, Heads of State and Heads of Delegations addressed the urgency of the situation and discussed multisectoral approaches to addressing antimicrobial resistance. This UN meeting elevated the discussion to a historic level and led to the approval of a declaration, but did not result in legally binding actions and failed to include language to eliminate excessive antibiotic use in animal agriculture. In an interview with Vox, Kevin Outterson, Professor of Law at Boston University, stated that “it has taken 15 years to get [antimicrobial resistance] back on the global agenda” since the UN last tried to take action in September 2001. Experts are warning that we may be entering or have already entered a post-antibiotic era […]

EPA Proposes that Glyphosate (Roundup) Does Not Cause Cancer

(Beyond Pesticides, September 21, 2016) The U.S. Environmental Protection Agency’s (EPA) Office of Pesticide Programs released last week  its Glyphosate Issue Paper in which the agency is proposing to classify glyphosate as “not likely to be carcinogenic to humans at doses relevant for human health risk assessment.” Glyphosate, the controversial active ingredient in Roundup, was classified in 2015 by the World Health Organization (WHO) as a “probable carcinogen” and numerous studies have associated the chemical with cancer and other human health issues. However, EPA’s proposed a classification that is contrary, not only to WHO’s, but also a position  it had previously held. The issue paper was released in preparation for the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) Scientific Advisory Panel (SAP) meeting, October 18-21, which convenes to review EPA’s evaluation of the carcinogenic potential of glyphosate. Glyphosate, produced by Monsanto, is one of the most popular weedkillers in the U.S., and the active ingredient in Roundup. Glyphosate is often promoted by industry as a “low toxicity” chemical and “safer” than other chemicals, yet has been shown to have  detrimental impacts  on humans and the environment. Given its widespread use on residential and agricultural sites, its toxicity is of increasing […]

Study Finds Bee Colonies Die-off as the Number of Different Pesticide Exposures Increase

(Beyond Pesticides, September 20, 2016) Honey bee colonies are declining as the total number of pesticide products they are exposed to increases, regardless of the amount of exposure, according to research published last week from scientists at the University of Maryland (UMD). The study aimed to look at honey bee colonies’ exposome, a term traditionally used in cancer research, defined as the measure of all exposures over an individual’s lifetime and how those exposures relate to health. In their investigation, researchers did not look at individual honey bees but instead treated the colony as a single super-organism, and based results on lifetime exposure to agricultural chemicals. The 91 honey bee colonies studied by researchers were exposed to a total of 93 different pesticide compounds throughout the course of their pollination season. Of these residues, 13 different compounds were found in bees, 61 in beebread (packed pollen within the hive), and 70 were found in wax. Researchers gauged the effect of pesticide exposure not only by looking at the number of pesticides in colonies, but also their toxicological relevance over a specific threshold, as well as through the calculation of a hazard quotient (HQ), which evaluates  the cumulative toxicity of various […]

Take Action to Ban Atrazine: EPA Must Protect Wildlife!

(Beyond Pesticides, September 16, 2016) Tell EPA to ban all uses of atrazine in the United States! Atrazine, widely used on food and feed crops, golf courses, and residential lawns, is a potent endocrine disruptor that is  strongly associated with birth defects, cancer, sex reversal and hermaphroditism in many different animals. The European Union and other countries have banned atrazine, however EPA continues to put U.S. citizens and the environment in harm’s way, allowing nonstop use of this toxic chemical. Sign Beyond Pesticides’ petition to ban atrazine by October 5, 2016. Atrazine is the second-most widely used pesticide in the U.S., with over 73 million pounds applied each year. Atrazine has washed into surface water and leached into groundwater, spurring community water utilities  across the U.S. to file class-action lawsuits to remove the pesticide from drinking water supplies. Even at levels established as “safe” or acceptable by EPA drinking water standards, atrazine is linked to endocrine-disrupting effects. EPA is not adequately assessing the effects of atrazine by using high dose testing models, which are not appropriate for hormonally-active substances  that  often show effects at minute doses. Studies by Tyrone Hayes, Ph.D., University of California, Berkeley,  and others have shown that […]

Legacy Contaminants Found in Swallow Eggs around the Great Lakes

(Beyond Pesticides, September 14, 2016) According to a recent study by the U.S. Geological Survey (USGS), high concentrations of dioxins and furans have been detected in tree swallow eggs collected near several sites around the Great Lakes. Other chemicals detected include polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs), which were at background levels. The study is part of efforts to clean up a toxic chemical legacy around the Great Lakes, and the researchers believe their results are critical to regulators to assess “bird or animal deformity or reproductive problems” The study, “Concentrations and spatial patterns of organic contaminants in tree swallow (Tachycineta bicolor) eggs at United States and binational Great Lakes Areas of Concern, 2010—2015,” used tree swallows to quantify current exposure to organic contaminants across all five Great Lakes including 59 sites within 27  Areas of Concern (AOCs)  and 10 nearby  locations. The Great Lakes Areas of Concern refers to a U.S.-Canada  Great Lakes Water Quality Agreement  (Annex 1 of the 2012 Protocol) that  defines AOCs as “geographic areas designated by the Parties where significant  impairment of beneficial uses  has occurred as a result of human activities at the local level.” An AOC is a location that has […]

GE Crops Lead to Increase in Toxic Herbicide Use

(Beyond Pesticides, September 8, 2016)  According to  a study  published last week by scientists at Iowa State, genetically engineered (GE) crops have not lived up to their promise to reduce pesticide use, and have instead led to an increase in toxic herbicide usage. The research, led by Edward Perry, Ph.D., found “clear evidence of increasing herbicide use by [GE] variety adopters over time for both soybeans and maize,” a finding that they credited partly to the emergence of weed resistance. The detailed dataset analyzed came from the company, GfK Kynetec, which conducts surveys of randomly selected farmers to assess decisions about pesticide and seed choices. The farm-level dataset that the researchers used was collected over the years 1998-2011 and includes a yearly average of 5,424 corn farmers and 5,029 soybean farmers. One striking trend that was noted since 1998 was the increase in the use of  glyphosate, the active ingredient in Monsanto’s Roundup. As of 2011, glyphosate was the primary herbicide used on soybeans, with just over 80% of total herbicide applied, and in corn it made up 40% of herbicide use, representing close to a 20-fold increase since 1998. Marketed as Roundup and other trade names,  glyphosate  is a […]

Bayer Increases Historic Takeover Bid For Monsanto

(Beyond Pesticides, September 7, 2016) Industry giant Bayer has increased its offer to acquire Monsanto to $65 billion, making it the largest all-cash takeover bid in history. Bayer is now offering $127.50 per share- up two percent from its earlier bid of $125. The pharmaceutical giant has been pursuing Monsanto in an attempt to become the world’s largest biotechnology and pesticide manufacturer. But many are concerned that should this merger be successful, farmers would have even fewer choices for acquiring seed, ensuring that the American food supply is dominated by a few mega-corporations. According to The Guardian, Bayer’s proposal will create a global pharmaceutical and farm supplies giant, just as  rival firms are also consolidating. ChemChina earlier this year offered  to buy Switzerland’s Syngenta for $43bn, after the latter rejected takeover approaches from the St. Louis-based Monsanto. This ChemChina-Syngenta merger is all set to move forward after getting approval from the regulatory agency, Committee on Foreign Investment in the U.S. (CFIUS). U.S. firms Dow Chemical and DuPont are pursuing a $130bn merger, to be followed by a breakup into three businesses. Bayer’s previous offers for Monsanto were rejected, but Monsanto remains open to further discussion. However, Monsanto has faced financial […]

FDA Bans Antibacterial Pesticide Triclosan in Soaps, While EPA Allows Its Use in Common Household Products and Toys

(Beyond Pesticides,  September 6, 2016) “The Food and Drug Administration (FDA) decision today to remove the antibacterial triclosan, found in liquid soaps (toothpaste use will remain), is a long time coming,” Jay Feldman, Executive Director of Beyond Pesticides, said today. He continued: “The agency’s failure to regulate triclosan for near two decades, as the law requires, put millions of people and the environment at unnecessary risk to toxic effects and elevated risk to other bacterial diseases. Now, FDA should remove it from toothpaste and EPA should immediately ban it from common household products from plastics to textiles.” Many companies had decided under consumer pressure to remove triclosan from its liquid soap products years ahead of the FDA decision today. FDA’s announcement today indicates that soaps containing the antibacterial ingredient triclosan do not have substantiated germ-killing health benefits. Beyond Pesticides raised concerns about the health effects of triclosan in 2004 in its piece The Ubiquitous Triclosan, and petitioned the agency to ban the chemical in 2005. In 2015, triclosan was banned in the European Union. For nearly two decades, scientific studies have disputed the need for the chemical and linked its widespread use to health and environmental effects and the development […]

Over Two Million Bees Killed after Aerial Mosquito Spraying in South Carolina

(Beyond Pesticides, September 2, 2016) Last Sunday, beekeepers in Dorchester County, South Carolina emerged from their homes to find their yards and  farms, once full of busy buzzing, littered with the honey bees. The cause was no mystery — a massive bee-kill had occurred due to aerial spraying of Naled, a highly toxic  insecticide used primarily to control adult mosquitoes. The county announced plans to spray two days before the incident, when four travel-related cases of Zika virus were confirmed in the area by the state Department of Health and Environmental Control. The spraying occurred between 6:30 and 8:30am. Naled is an organophosphate insecticide with the highest acute toxicity of any mosquitocide. According to the Environmental Protection Agency (EPA), Naled can cause cholinesterase (an enzyme necessary to the transmission of nerve impulses) inhibition in humans, meaning that it can overstimulate the nervous system causing nausea, dizziness, confusion, and, at very high exposures (e.g., accidents or major spills), respiratory paralysis and death. Naled is highly toxic to honey bees. In Dorchester County, beekeepers say that the spray announcements did not come soon enough. Flowertown Bee Farm and Supply lost more than 2.3 million insects from 46 hives, according to co-owner Juanita […]

Cannabis Certification Program Restricts Pesticides and Residues

(Beyond Pesticides, August 31, 2016) Last week, a Denver marijuana company went through its first inspection for the Colorado-based Organic Cannabis Association’s (OCA) new “pesticide-free” certification. This voluntary certification program was developed by OCA following an indefinite postponement of the Pesticide-Free Marijuana Bill, HB 16-1079 by the Colorado Senate and the failure of  the Colorado Department of Agriculture (CDA) to implement meaningful regulations to protect  users within the state from pesticides that are not regulated  for use in cannabis production by the U.S. Environmental Protection Agency (EPA) and the states. While the certification program is characterized as “pesticide-free,” it is focused on residues on the finished product, allowing the use of pesticides that do not appear on the narrow list of those restricted by the state of Colorado. The certification is a a step in the right direction for consumers who wish to protect themselves from unwanted pesticides in their cannabis products, however it is important to note that it  does not equate to a USDA organic inspection, as marijuana remains illegal at the federal level and is unable to qualify for certification under the USDA National Organic Program (NOP). While discussing his inspiration for developing such a program, OCA […]

Minnesota Governor Issues Executive Order Protecting Pollinators from Pesticides

(Beyond Pesticides, August 30, 2016) Last week, Minnesota Governor Mark Dayton issued an executive order aimed at reversing pollinator decline in the state by limiting the use of toxic, systemic neonicotinoid (neonics) pesticides. The order tasks state agencies with a range of pollinator protective activities, and follows the completion of a Special Registration Review of Neonicotinoid Pesticides conducted by the Minnesota Department of Agriculture. Given that a change in administration could lead to a rescinding of an executive order, it is critical that advocates continue to pressure for concrete legislative changes that institutionalize bee protective practices. “Bees and other pollinators play a critical role in supporting both our environment, and our economy,” said Governor Dayton. “This order directs state government to take immediate action to alleviate the known  risks that pollinators face. It also will create a new task force to study the issues impacting pollinators and recommend long-term solutions.” The executive order directs the Department of Agriculture to immediately initiate steps requiring neonics only be applied when there is “an imminent threat of significant crop loss.” This move applies  to sprays, drenches, or granular applications of neonics, however, and not seed coatings, which will require separate legislative action to […]

Judge Orders Release of Terminix Documents in Methyl Bromide Poisoning of Family

(Beyond Pesticides, August 26, 2016) Virgin Islands Superior Court Judge, Harold Willocks denied a request made by Terminix to stop a subpoena for Terminix documents in the methyl bromide poisoning case  issued  by Attorney General Claude Earl Walker, according to The Virgin Islands Consortium. The paper reported that the subpoena ordered the pest control company to provide documents and information relating to an ongoing investigation by the Department of Justice (DOJ). This follows two settlement agreements made by Terminix; one to pay $10 million to DOJ and the Environmental Protection Agency (EPA) for violating the Federal Insecticide, Fungicide and Rodenticide Act, and another to pay $87 million to the Esmond family, poisoned by the misuse of a neurotoxic pesticide fumigant, methyl bromide, when they vacationed in the Virgin Islands in the spring of 2015. According to the Virgin Islands Consortium, DOJ launched  another investigation into Terminix after the Esmonds were poisoned to determine if there had been a violation of the Criminally Influenced and Corrupt Organizations Act (CICO). Attorney General Walker issued the original subpoena on April 28, requesting that Terminix surrender all information related to the purchase, use and import of methyl bromide obtained within the past three years.

Banned Chemicals Linked to Increased Autism Risk

(Beyond Pesticides, August 24, 2016) Researchers at Drexel University report that higher levels of some organochlorine compounds during pregnancy are associated with autism spectrum disorder (ASD) and intellectual disability (ID). The organochlorine compounds under study have long been banned in the U.S., and include pesticides like DDT, underscoring how pervasive and persistent these chemicals are, and their continued impact on human health. The research is reported in the study  Polychlorinated Biphenyl and Organochlorine Pesticide Concentrations in Maternal Mid-Pregnancy Serum Sam ples: Association with Autism Spectrum Disorder and Intellectual Disability,  which examines whether prenatal exposure to polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs) influences offspring risk of ASD and intellectual disability without autism (ID). According to the research, children born after being exposed to the highest levels of organochlorines during their mother’s pregnancy are roughly 80 percent more likely to be diagnosed with autism when compared to individuals with the very lowest levels of these chemicals. The team looked at a population sample of 1,144 children born in Southern California between 2000 and 2003. Data was accrued from mothers who had enrolled in California’s Expanded Alphafetoprotein Prenatal Screening Program, which is dedicated to detecting birth defects during pregnancy. Participants’ children were […]

Pesticide Resistant Whitefly in U.S. Points to Need for Organic Management Strategies

(Beyond Pesticides, August 22, 2016) An invasive whitefly that is resistant to pesticides has been found outdoors in the U.S. for the first time, prompting a public discussion hosted by the University of Florida Extension Miami-Dade in Homestead, Florida on July 29. And while the fears amongst fruit and vegetable growers over crop devastation are valid, little attention has been paid to the viability and effectiveness of organic and cultural management practices in preventing and managing  whiteflies. Meanwhile, chemical intensive agriculture, which is dependent on insecticides to control whiteflies, is harming the same beneficial insects that act as natural predators to the whitefly. The pest, a Q-biotype of the sweet potato whitefly, Bemisia tabaci, has been present in greenhouses around the U.S. since 2004, when it was first found in Arizona. According to Florida Agriculture Commissioner Adam Putnam, this pest “poses a serious risk to Florida’s $120 billion agriculture industry and the more than two million jobs it supports.” Whiteflies are tiny, fluid-sucking insects that thrive in warm weather and become abundant in ornamental and vegetable plantings. This particular species breed year round and large colonies often develop on the undersides of leaves. Whiteflies draw fluid of out a plant […]

More Evidence Shows Neonics Harm Butterflies

(Beyond Pesticides, August 19, 2016) A study published earlier this week has found that the increasing use of neonicotinoid (neonic) insecticides is correlated with a steep decline in butterfly health and reproductive success — as more neonics are used, butterflies are struggling to survive. This study adds to previous evidence that demonstrates, in addition to bees, neonics can cause serious harm to other important pollinators. The study, Increasing neonicotinoid use and the declining butterfly fauna of lowland California, looks at 67 species of butterfly fauna in the lowlands of Northern California at four sites that were  monitored for approximately 30-40 years. The sites include Suisun Marsh, West Sacramento, North Sacramento, and Rancho Cordova. While controlling for land use and other factors, the researchers found a correlation between butterfly population decline and increasing neonic applications, which also appeared to be more severe for smaller-bodied species. According to the researchers, the results suggest that neonics could influence non-target insect populations when applied nearby. This study contributes to the mounting evidence that neonicotinoid insecticides are linked to pollinator decline. Neonics have increasingly been the subject of studies that highlight a relationship between neonicotinoid exposure  and harmful effects to pollinators. These effects are being […]

Half of the Total Decline in Wild Bees throughout the UK Linked to Use of Neonics

(Beyond Pesticides, August 18, 2016)   Decline of wild bee populations is linked to the use of toxic, systemic neonicotinoid (neonic) pesticides used on oilseed rape (canola), according to new research done by a team of scientists at the Centre for Ecology and Hydrology in the United Kingdom. In addition to corn and soybeans, canola is one of the main crops treated with neonicotinoids worldwide. Neonic pesticides have long been identified as a major culprit in bee decline by independent scientists and beekeepers, yet chemical manufacturers like Bayer and Syngenta have focused on  other issues such as the varroa mite. As Beyond Pesticides put it in the spring 2014 issue of Pesticides and You, the issue of pollinator decline is No Longer a Big Mystery, and urgent action is needed now to protect pollinators from these toxic pesticides. Neonics are associated with decreased learning, foraging and navigational ability, as well as increased vulnerability to pathogens and parasites as a result of suppressed bee immune systems. In addition to toxicity to bees, pesticides like neonicotinoids have been shown to also adversely affect birds, aquatic organisms and contaminate soil and waterways, and overall biodiversity. The study, Impacts of neonicotinoid use on long-term […]
