(Beyond Pesticides, October 7, 2016) For the first time in U.S. history, the U.S. Fish and Wildlife Service (FWS) has added a group of bees to the list of Endangered Species. FWS published a final rule last Friday that  declares seven species of yellow-faced bees (genus Hylaeus) that are native to Hawaii as endangered. This announcement immediately follows last week’s news that FWS has proposed listing the rusty patched bumble bee as an endangered species under the Endangered Species Act (ESA). While the decision is great news for these bees and the environmental groups who have fought to protect them, there is still much work that needs to be done, and FWS says that it needs additional time to identify specific areas to be designated as critical habitat for the endangered bees. Further, though FWS has identified many threats to bees, including habitat loss and degradation due to urbanization, and other human activities, the final rule does not specifically point to pesticides. However, there is an overwhelming amount of research demonstrating that neonicotinoid insecticides, working either individually or synergistically, play a critical role in the ongoing decline of bees and other pollinators. Neonicotinoids have been linked to a range of […]

(Beyond Pesticides September 28, 2016) This summer, Beyond Pesticides teamed up with The Bees Waggle to develop pollinator curriculum with the intent of making it widely available for public use. The goal of the curriculum is to provide a fun, hands-on lesson about pollinators and their importance to food production. Through the lesson, students learn about biodiversity, soil health, and the negative effects of pesticides on pollinators, while participating in a variety of activities on these issues. In addition, Beyond Pesticides  will offer small grant opportunities for teachers in school districts that serve low-income students in order to offset the cost of materials and supplies required to conduct the pollinator lesson plan. The launch of this educational  program is an expansion  of the classroom lessons  that Beyond Pesticides’ staff and Jessica  Goldstrohm, owner and head educator of The Bees Waggle, brought to District of Columbia Public Schools (DCPS) this  June as part of the lead up to  National Pollinator Week. The education team visited two first-grade DCPS classrooms, where students participated in lessons outlined in  Beyond Pesticides’ pollinator curriculum. Students gained a deeper understanding of the issues facing honey bees and other pollinators, and learned about ways they and their […]

(Beyond Pesticides, September 23, 2016) The U.S. Fish and Wildlife Service (FWS) has proposed listing the rusty patched bumble bee as an endangered species under the Endangered Species Act (ESA). This is a victory for environmental groups who have fought to protect the rusty patched bumble bee from widespread threats such as habitat loss and pesticide use. The FWS proposal opens a 60-day public comment to allow agencies, groups and interested people to comment and provide new information. The public comment period is open through November 21, 2016. You can submit comments soon by visiting the docket, here. According to FWS, the rusty patched bumble bee was once widespread across the United States and parts of Canada, but declined dramatically in the 1990s. Their populations dwindled and have declined by 91 percent. FWS acknowledged  that the bumble bee populations considered for this proposal have not been reconfirmed since the early 2000s, meaning that currently there may be even less of the species left. Threats to the rusty patched bumble bee include diseases introduced by commercial bumble bees that are not free of pathogens and are released near wild populations. Climate change plays a part, along with habitat loss from industrial […]

(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 […]

(Beyond Pesticides,  September 19, 2016) Last week, a  proposed Bayer-Monsanto merger was announced, as 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. It is the merger of two companies that have been tied to past atrocities against humanity, one whose chemical product was  used  to kill  concentration camp victims under Adolf Hitler and the other a producer of the  deadly defoliant, Agent Orange, which was sprayed by the U.S. government over Vietnam and left a legacy of health damage to the Vietnamese people and U.S. veterans of the armed forces. At the same time, these companies are currently embroiled in controversy on  some of the most hazardous pesticides, including glyphosate (RoundupTM) and neonicotinoids, used in food production and in communities and home gardens    —continuing a history of profiting from a technology that has adverse effects on human life and the environment, but has been shown to be unnecessary and unsustainable in food production and the management of lawns, landscapes, playing fields, and parks. In 1995, the Associated Press reported that the then-CEO of Bayer,  Helge Wehmeier, apologized to Elie Wiesel, Ph.D., holocaust […]

(Beyond Pesticides, September 13, 2016) Land suitable for commercial beekeepers in the U.S. Northern Great Plains (NGP) is declining rapidly, according to a new study released earlier this month by the U.S. Geological Service (USGS). The region, which supports over 40% of managed honey bee colonies, is quickly replacing suitable pollinator habitat with more and more pesticide-intensive biofuel crops, particularly corn and soybean, as a result of increased crop prices and federal subsidies for biofuels. The concerning trend adds another layer of stress not only to honey bee colonies, but beekeepers whose livelihood depends on the health of their commercial livestock. From early summer to mid-fall, roughly one million honey bee colonies make their way through the Northern Great Plains of North and South Dakota. The area is not usually a stop for pollination services, but a place where beekeepers go to generate a honey crop and improve the health of their colonies. Most of the colonies that summer in the NGP are trucked across the country to pollinate fruiting crops like apples, cherries, melons, and almonds during the winter, or are otherwise moved south to produce packaged bee colonies or queens. According to the USGS study, published in the […]

(Beyond Pesticides, September 9, 2016) On Wednesday, City Council members of South Portland, Maine cast their final votes to pass an ordinance that bans the use of toxic lawn pesticides on private and public land. The ban, which passed 6-1, is an important public health measure in the protecting 25,000 residents,  the largest jurisdiction in the state to-date to adopt such as measure. In 2014, the Town of Ogunquit, Maine was the first jurisdiction to ban toxic lawn pesticides on both private and public land. Maine’s status as one of only seven states that does not preempt  local governments’ authority to restrict the use of pesticides on land within their jurisdiction empowers local governments to take this kind of protective action. Supporters of this ordinance, led by the local organization Protect South Portland, and supported by statewide organizations and  Beyond Pesticides, put together an effective campaign to educate council members, the public, and the media about the dangers of pesticides, and the effectiveness of organic land management practices that do not utilize toxic pesticides. Under the legislation, the provisions will be phased in, starting with city property on May 1, 2017, private property beginning May 1, 2018, and to golf […]

(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 […]

(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 […]

(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 […]

(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 […]

(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 […]

(Beyond Pesticides, August 17, 2016) In response to dramatic scientific findings, a severe decline in bee populations, and growing public demand for bee-safe plants, a new report confirms  the decision  of  major retailers to phase-out  the sale of flowers and trees treated with the pesticides most closely associated with the decline —neonicotinoids. A new report released by Friends of the Earth, analyzes plants purchased at  Home Depot,  Lowe’s, Ace Hardware,  True Value  and  Walmart. Many of these major retailers have made public commitments to stop selling bee-toxic neonicotinoids and treated plants. Additionally, the states of Maryland and Connecticut have passed legislation that stops the retail sales of neonics. The report,  Gardeners Beware 2016, released yesterday is a follow-up to previous testing that demonstrated the presence of bee-toxic neonicotinoid insecticides in more than half of bee-attractive flowers tested. The 2016 analysis found that 23 percent of flowers and trees tested contain neonicotinoid insecticides at levels that can harm or kill bees, compared to 51 percent in 2014, indicating that stores are selling far fewer plants treated with bee-killing neonics. This reduction is likely due to changes in store policies that commit retailers to eliminate neonicotinoid use on garden plants. Retailer commitments […]

(Beyond Pesticides, August 12, 2016) A new study by a team of scientists at Virginia Tech finds that commonly used in-hive pesticides result in changes to the honey bee gut microbiome. The study, Honey bee gut microbiome is altered by in-hive pesticide exposures, was led by Virginia Tech associate professor of horticulture, Mark Williams, Ph.D., and colleagues from Oregon State University and North Carolina State University. This research, published several weeks ago in the journal Frontiers in Microbiology, aimed to determine the microbiome of honey bees (Apis mellifera) after being exposed to three common pesticides. Coumaphos and tau-fluvalinate, both common miticides used in conventional beekeeping, and chlorothalonil, a fungicide commonly detected in hives, were used as pesticide treatments in the study. While this  research contributes to the already established body of science on the complexity of pesticide exposure effects, beekeepers reported the steepest, and then sustained, declines in honey bee populations after the large  increase in  neonicotinoid pesticide  use in the early 2000’s. Beekeepers nationwide suffered  their highest hive losses of 44.1% in the last national survey from April 2015-2016. While it is likely that neonicotinoids are not the sole factor in pollinator decline, they have been found to exacerbate […]

(Beyond Pesticides, August 10, 2016) New research connects 78 pesticides commonly used by farmers with many adverse respiratory effects, including both allergic and non-allergic wheeze. The study, Pesticides Are Associated with Allergic and Non-Allergic Wheeze among Male Farmers, was led by NC State environmental epidemiologist, Jane Hoppin, ScD and colleagues from the National Institute of Environmental Health Sciences (NIEHS), the National Cancer Institute, Westat and the National Institute for Occupational Safety and Health (NIOSH). This is one of the most comprehensive evaluations of pesticides in relation to wheeze that has been evaluated to date, finding that several commonly used pesticides in both agriculture and residential settings can cause adverse respiratory effects. “Fifty-one of the pesticides we tested in this study had never been analyzed in terms of their effects on respiratory outcomes. And some of them, like glyphosate, 2,4-D and permethrin, aren’t just used on farms. They’re used residentially now to kill weeds or treat fleas on pets,” said Dr. Hoppin. “We believe it’s important information that will help people make decisions about pesticides.” Researchers used interview data from the 2005-2010 Agricultural Health Study (AHS) to assess the correlation between pesticide exposure and wheeze in male farmers. 22,134 farmers were […]

(Beyond Pesticides, August 9, 2016) Farmers in Missouri, Arkansas, and Tennessee are confronting widespread crop damage and bracing for lower yields as a result of agrichemical giant Monsanto’s botched roll-out of new genetically engineered soybean and cotton crops. The company, whose current line of glyphosate-tolerant crops are failing to control weeds throughout the U.S. and across the globe, developed a new line of soybean and cotton with traits that make it tolerate applications of an older herbicide dicamba. However, while its seeds are available for purchase on the market, and Monsanto is encouraging farmers to grow them, the company has yet to receive EPA regulatory approval for the dicamba herbicide meant to be used with the plants. A spate of news reports over the past two  months in southern soybean growing regions finds that many farmers are illegally applying off-label dicamba-based herbicides to Monsanto’s new GE crops in an effort to control weeds resistant to glyphosate. Use of this highly volatile herbicide is causing widespread crop damage not only to soybeans that don’t carry the resistance trait, but other crops in the region, including peaches, melons, and tomatoes. Dicamba has a strong propensity to volatilize small particles of the herbicide […]

(Beyond Pesticides, August 5, 2016) Concerned health officials in Miami, Florida are investigating suspicions that Zika-spreading mosquitoes have become resistant to the pesticides commonly used synthetic pyrethroid insecticides used in mosquito control. As the region works to contain a Zika outbreak in northern Miami, officials are beginning to recognize that broadcast pesticide applications are not effective at controlling populations, and are looking into cases in the U.S.  and in other parts of the world of mosquitoes developing resistance to chemical controls, or whether other factors are at work. At the same, the broadcasting of the pesticides by truck and plane and the resulting exposure to people and the environment also raise serious health issues. The Aedes aegypti mosquito, which has the ability to live indoors and reproduce even in tiny pools of water, is the primary way the Zika virus is spread, although there are reports that the disease can also be transmitted through sexual contact. Zika virus has been linked to cases of microcephaly, in which babies are born with underdeveloped brains. The virus has been detected in several Latin American countries, including Brazil where the outbreak was first observed and linked to increased cases of microcephaly. However, locally […]

(Beyond Pesticides, July 28, 2016)   Led by the Institute of Bee Health at the University of Bern, new research finds evidence that two commonly used neonicotinoid (neonic) insecticides have a significant adverse effect on the reproductive ability of male honey bees (drones) and queen bees in managed and wild colonies. The study,  Neonicotinoid insecticides can serve as inadvertent insect contraceptives, published in  Royal Society Journal Proceedings B, focuses on the differences in lifespan and viability of sperm throughout exposed and unexposed drones. Since 2006, honey bees and other pollinators in the U.S. and throughout the world have incurred ongoing and rapid population declines from hive abandonment and bee die-off in a phenomenon known as colony collapse disorder (CCD).  Neonicotinoids, such as imidacloprid, thiamethoxam and clothianidin, have been found by  a growing body of scientific literature  to be linked to the CCD phenomenon and  pollinator decline in general. While science has become increasingly clear that these  pesticides  play a critical role in contributing to  the ongoing decline of bee health, this is one of the first to look at how these chemicals specifically effect the fertility of male honeybees. In the study, scientists randomly assigned honeybee colonies consisting of drones […]

(Beyond Pesticides, July 21, 2016) An investigative report released yesterday by Center for Biological Diversity (CBD) concludes  that, over the past six years, the U.S. Environmental Protection Agency (EPA) has approved nearly 100 pesticide products with chemical mixtures that elevate the formulations’  toxicity, but are not specifically evaluated  by the agency. CBD finds that these formulations add  more stress to already-jeopardized pollinators and rare plants. The report Toxic Concoctions: How the EPA Ignores the Dangers of Pesticide Cocktails, highlights a long-running blind spot within EPA’s pesticide evaluation program, which Beyond Pesticides has long sounded the alarm on: the risk associated with combining mixtures of different pesticide active ingredients, which independent science shows may be more toxic than a single active ingredient by itself, also known as pesticide synergism. The mixtures occur as a result of multiple ingredients in individual products or  because of exposure to multiple pesticide product residues in food, air, water, and land areas, such as lawns, playing fields, and parks. “It’s alarming to see just how common it’s been for the EPA to ignore how these chemical mixtures might endanger the health of our environment,” said Nathan Donley, Ph.D., a scientist with the CBD, and author of […]

(Beyond Pesticides, July 20, 2016) Farmers and land managers across the U.S. are being encouraged to plant pollinator habitat adjacent to farmlands to provide shelter and food for pollinator species. But according to a new study published last week, these conservation areas still put bees at risk for pesticide contamination, as they fail to provide spatial or temporal relief. This study emphasizes that meaningful solutions to reversing pollinator decline does not lie with focusing on planting pollinator habitat, but ensuring that these refuge areas are free from pesticide contamination, highly toxic to bees and other pollinators, and reducing the reliance on toxic chemical inputs in agriculture and other landscapes. The study, “Neonicotinoid-contaminated pollinator strips adjacent to cropland reduce honey bee nutritional status,” finds that pollinator habitat adjacent to agricultural areas not only becomes a source for pesticide, especially neonicotinoid, exposures, but also poses significant risk to honey bees. The authors, Christina Mogren, PhD, and former USDA entomologist, Jonathan Lundgren, PhD, initially sought to study whether increasing forage by planting pollinator habitat in an agricultural-dominated region would serve to buffer against the harmful effects of plant-incorporated pesticides. However, the authors note that it soon became apparent that the unintended consequence was […]

(Beyond Pesticides, July 12, 2016) Canadian environmental organizations sued the  Canadian Pest Management Regulatory Agency (PRMA) last week in a bid to overturn the approval of two neonicotinoid pesticides linked to the decline of honey bees and wild pollinators. The move comes amid growing awareness, action, and scientific evidence linking this widely used class of insecticides to the global decline of pollinator populations. The lawsuit, filed  by Ecojustice on behalf of  The David Suzuki Foundation, Friends of the Earth Canada, Ontario Nature, and the Wilderness Committee, argues that pesticide products containing two neonicotinoids, clothianidin and thiamethoxam, are unlawfully registered in Canada. The groups allege that PMRA failed to ensure that it had the data necessary to determine the environmental risks, particularly those concerning pollinators, posed by the chemicals. “The PMRA has taken a see-no-evil, hear-no-evil, speak-no-evil approach by repeatedly registering these neonicotinoid pesticides without important scientific information on their risks to pollinators,” said Charles Hatt, staff lawyer at Ecojustice. Under Canada’s Pest Control Products Act, PMRA must have “reasonable certainty” that a pesticide will not cause harm to the environment before it is registered. The groups also note that several thiamethoxam-based products have been registered by the agency for years […]

(Beyond Pesticides, July 5, 2016) Last week, Malibu City Councilmembers, in a unanimous decision (5-0), voted to make Malibu, California’s (CA) public spaces poison free, which means an immediate ban on all pesticides, rodenticides and herbicides. During a marathon meeting that ran into the early hours past midnight, more than 24 Malibu residents and stakeholders came to give public comments on pesticide use on public parks and city property. You can view the city council meeting here. The entire discussion and vote is included, starting at 3:29:37 (or section 6.A.). Many of the residents were with an community  group called Poison Free Malibu, which is a group that advocates for the elimination of toxic pesticide use in the area. According to the Malibu Times, Kian Schulman, RN, founder of Poison Free Malibu, gave a presentation on the effects of pesticide chemicals and their connection to diseases such as cancer and neurological issues like ADHD and Alzheimer’s. Ms. Schulman’s presentation included a picture of a city worker spraying pesticides on Legacy Park, while wearing a full hazmat suit as a child rode their bicycle close by. Several Poison Free Malibu supporters attended the meeting and gave a presentation on the adverse […]

(Beyond Pesticides July 1, 2016) Lawmakers in France approved plans to totally ban neonicotinoid pesticides by 2018, based on their link  to declining populations of pollinators, specifically bees. This new restriction would go above and beyond current European Union (EU) restrictions on neonicotinoids, which limit the use of neonicotinoids, but do not ban them. The outright ban on neonicotinoid pesticides in France was adopted by a narrow majority of the  country’s  National Assembly, as part of a bill on biodiversity. While the bill must still gain the approval of the French Senate, which rejected it in a previous reading, passage by the Assembly is significant, as France becomes the first country to join state and local movements to eliminate the use of these toxic chemicals. Neonicotinoids have been found by  a growing body of scientific literature  to be linked to honey bee and other pollinator declines. In light of these findings, in 2013 the European Commission  voted to suspend  the use of neonicotinoid pesticides for two years. The ban came several months after the European Food Safety Authority (EFSA)  released a report  identifying “high acute risk” to honey bees from uses of certain neonicotinoid chemicals.   Along with recent reports […]
