(Beyond Pesticides, May 2, 2016) A study published online last week has examined the effects of three neonicotinoids (neonics) on bumblebee colonies, from live bee kills to changed sex ratios. Neonics have been widely cited as contributing to  the demise of both managed and wild bee and pollinator populations. They can cause  changes in bee reproduction, navigation, foraging, and even the suppression of bee immune systems. The study, published in Scientific Reports, looked at field-relevant levels (2.5 parts per billion) of imidacloprid, thiamethoxam, and clothianidin, and found compound-specific effects at all levels, including within individual bee cells, individual bees, and whole colonies in semi-field conditions. Given the limitations of laboratory studies and field studies, researchers conducted a semi-field study to try to recreate and represent real world exposure patterns. The neonics were provided to the bees as an optional supply of sugar syrup, but were free to forage and did need to gather pollen in order to grow and raise offspring. Researchers found that imidacloprid and clothianidin displayed abilities to affect neuronal Kenyon cells, which help with learning, memory and multisensory integration. At the whole colony level, thiamethoxam altered the sex ratio, leaving more males than females. Both imidacloprid and […]

(Beyond Pesticides, April 29, 2016) Traces of pesticides, including the long-banned organochlorine chemical DDT, have been found in Western pond turtles, insects, and soil sediment at Sequoia National Park, according to a study.  The study, entitled Organic contaminants in western pond turtles in remote habitat in California  and published in the journal Chemosphere, surveys a suite of 57 current- and historic-use pesticides, polychlorinated biphenyls (PCBs), and polycyclic aromatic hydrocarbons (PAHs) in the western pond turtle, along with their potential prey items and habitat. California study sites include Sequoia National Park, Whiskeytown National Recreation Area, and Six Rivers National Forest, all of which are downstream of undeveloped watersheds and varied in distance from agricultural and urban pollution sources. Researchers found that organic pollutants are widespread in the western pond turtle, which has conservation status; that pesticides are prominent in Sequoia National Park, which is downwind of heavy agriculture; and that the legacy  pesticides and PCB concentrations indicate that bioaccumulation is occurring. Brian Todd, Ph.D., an associate professor of wildlife, fish, and conservation biology at University of California Davis, co-authored the study. Dr. Todd said controlling the flow of pesticides into national parks is pretty much impossible. “Sequoia National Park is very […]

(Beyond Pesticides, April 28, 2016) This week, Antioch College in Yellow Springs, Ohio,  became the third university to become a neonicotinoid-free campus.  Antioch College gains recognition from the Beyond Pesticides’ and Center for Food Safety’s  BEE Protective  Campaign, which seeks to protect honey bees and other pollinators from harmful pesticides. Signing the  BEE Protective  resolution, Antioch signaled its continued commitment to using neonicotinoid-free insecticides on campus, making them one of the leading higher education institutions committed to the protection of pollinator species. In addition to joining the Bee Protective Campaign, the Village of Yellow Springs, where Antioch is located,  is  considering an organic land care policy, and Beyond Pesticides is working with the Village to assist with a transition to organic turf care. “At Antioch College, we have an opportunity, and an urgency, to be change leaders in turning around pollinator decline, exposing misleading research and recognizing the importance of inter-species cooperation. To paraphrase our president Thomas Manley, ”˜If we are not leaders in discovering and implementing  new and better ways of living  , then what is the point?’” said Beth Bridgeman, the faculty member who drove the effort to ban neonicotinoids from campus. Antioch students and staff maintain about […]

(Beyond Pesticides, April 21, 2016) A report released Tuesday by the Alliance for Natural Health (ANH) shows that glyphosate residues are widely distributed in common breakfast foods, such as bagels, cereals, creamers, and eggs. Glyphosate is a pervasive and toxic chemical found in Monsanto’s Roundup weedkiller and was classified by the International Agency for Research on Cancer (IARC) as a probable human carcinogen in 2015. The report looks at conventional and organic-certified versions of 12  popular breakfast foods and ingredients (a total of 24 items) and finds that many of the sample foods or ingredients contain detectable levels of glyphosate. Testing was done by an independent laboratory using the ELISA (enzyme-linked immunosorbent assay) method. Categories tested were: flour, corn flakes, instant oatmeal, bagels, yogurt, bread, frozen hash browns, potatoes, cream of wheat, eggs, non-dairy creamers, and dairy based coffee creamers. Of note is the finding that a sample of organic cage-free eggs contain more glyphosate than the allowable tolerance level. The lab found glyphosate residue levels of 169 parts per billion (ppb), while the allowable tolerance level is only 50ppb. The report acknowledges that the effects of other chemical ingredients in glyphosate formulations have not been evaluated, and the consequences […]

(Beyond Pesticides, April 18, 2016) Major pesticide manufacturer Scotts Miracle Gro announced on Tuesday that it will immediately being phasing out neonicotinoid insecticides, including imidacloprid, clothianidin, and dinotefuran from its outdoor-use Ortho brand by 2017. Neonicotinoids (neonics) have  consistently been implicated  as a major contributing factor in pollinator declines. They can cause  changes in bee reproduction, navigation, and foraging, and even the suppression of bee immune systems. In its press release, the Ortho brand announced that it was partnering with Pollinator Stewardship Council to help educate homeowners on the “safe and appropriate use of pesticides.” “While agencies in the United States are still evaluating the overall impact of neonics on pollinator populations, it’s time for Ortho to move on.” Tim Martin, general manager of the Ortho brand said. “As the category leader, it is our responsibility to provide consumers with effective solutions that they know are safe for their family and the environment when used as directed. We encourage other companies and brands in the consumer pest control category to follow our lead.” Neonics have emerged as the leading class of pesticides responsible for bee decline. While neonicotinoid insecticides have been responsible for high profile bee kills from high doses […]

(Beyond Pesticides, April 14, 2016) Two-thirds of Europeans support a ban on glyphosate, the  most widely used agricultural chemical in the world, according to a new poll. This as Germany plans to formally support a European Union (EU) plan to re-license the use of the chemical. Monsanto’s glyphosate, the active ingredient in the popular weedkiller, Roundup, has been classified as a probable carcinogen by the World Health Organization’s (WHO) International Agency for Research on Cancer (IARC), is detected in food, breast milk, and urine, and is increasingly used on genetically engineered (GE) crops, leading to the proliferation of resistant “superweeds” and environmental contamination. The poll conducted by Yougov, an international internet-based market research firm, surveyed more than 7,000 people across the EU’s five biggest countries and find  three-quarters of Italians, 70% of Germans, 60% of French and 56% of Britons support a ban on glyphosate. Despite this, the EU is moving forward on whether to approve a European Commission proposal to extend the authorization of glyphosate for another 15 years until 2031. The existing authorization is due to lapse in June 2016. The decision was delayed after the IARC classified glyphosate as a  Group 2a “probable” human carcinogen  based on […]

(Beyond Pesticides, April 12, 2016) Two commonly used pesticides are “likely to adversely affect” 97% of species listed under the Endangered Species Act (ESA), according to a first of its kind national assessment by the U.S. Environmental Protection Agency (EPA). The determination is part of a settlement reached by EPA and the Center for Biological Diversity, which requires the agency to complete a review of the impact of organophosphate pesticides chlorpyrifos, malathion, and diazinon by December 2017, and two carbamate class pesticides, methomyl and carbaryl, by the end of 2018. Under ESA Section 7, any agency action that it  authorizes, funds, or carries out must find that it  “is not likely to jeopardize the continued existence of any endangered species or threatened species or result in the destruction or adverse modification of habitat.” Under ESA, EPA is required to consult with the U.S. Fish and Wildlife Service (FWS) and National Marine Fisheries Service (NMFS) when registering a pesticide, in order to mitigate risks to endangered species. However, EPA routinely disregards this requirement, and has been sued numerous times for failing to ensure adequate protections for endangered species. Although CBD’s original lawsuit targeted potential pesticide impacts on California’s threatened red-legged frog, […]

(Beyond Pesticides, April 11, 2016) In a historic move, the Maryland legislature voted to become the first state in the nation to ban consumers from using products containing neonicotinoid pesticides, a class of bee-toxic chemicals that has been linked to the startling decline in bees and other pollinators around the world. The bill now heads to Governor Larry Hogan to sign or veto. The Pollinator Protection Act was approved by lawmakers on Thursday by  a 98-39 vote in the Maryland House of Delegates. While consumers will not be allowed to buy pesticide products containing neonicotinoids starting in 2018, the legislation’s  reach does not extend to farmers, veterinarians, and certified pesticide applicators, who will still be permitted to apply  the chemicals. Consumers can also buy treated plants and seedlings from stores without any labeling. Cumulatively, these present major sources of exposure for bees and other pollinators. The bill originally included a requirement that companies put labels on plants and seeds that are treated with neonicotinoids, but that provision was ultimately pulled from the bill. Hardware stores  like Home Depot and Lowe’s  had previously announced that they were voluntarily phasing out the supply of neonicotinoid-treated plants over the next two to three […]

(Beyond Pesticides April 6, 2016) Hot off the heels of the NCAA basketball tournament, a national title is not the only thing Villanova University has to celebrate this week. The campus, located near Philadelphia, PA, recently became the second school in the nation to receive recognition from the Beyond Pesticides’ and Center for Food Safety’s BEE Protective Campaign, which seeks to protect honey bees and other pollinators from harmful pesticides. Signing the BEE Protective pledge, Villanova signaled its continued commitment to using neonicotinoid-free insecticides on campus, making them one of the leading higher education institutions committed to the protection of pollinator species. “For Villanova, sustainability is not just about energy and recycling,” said Liesel Schwarz, Villanova’s Sustainability Manager. “We look to make all aspects of campus life sustainable, including how we treat our campus grounds. This recognition only further solidifies the wonderful work our grounds department has done to not only make the campus beautiful and inviting for people, but also for pollinators.” Villanova maintains more than fifty pollinator-friendly plants on campus, including aster, black-eyed Susans, milkweed and mint. Along with planting pollinator-friendly habitat, the elimination of neonicotinoid pesticides on campus is an exemplary move by Villanova to protect pollinators. […]

(Beyond Pesticides, April 4, 2016) Pesticides widely used in rice paddies in Japan are harming  dragonflies. The study, conducted by researchers at Japan’s National Institute for Environmental Studies, finds that the insecticide fipronil significantly reduces the population of adult dragonflies, more so than any other pesticide treatment. The study, titled Fipronil application on rice paddy fields reduces densities of common skimmer and scarlet skimmer  and published in the journal Scientific Reports, investigated the impact of neonicotinoids, which have been linked to bee die-offs around the world, and chlorantraniliprole, which, like neonicotinoids and fipronil, is a systemic pesticide that is taken up by the plant and subsequently expressed in pollen, nectar, and guttation droplets. Plankton species were adversely  affected by clothianidin, a neonicotinoid, and chlorantraniliprole, but they recovered after concentrations of the chemicals decreased. Koichi Goka, Ph.D., a senior researcher at the institute, said nymphs living near the soil are particularly vulnerable to toxic chemicals, according to The Asahi Shimbun. “The density of insecticidal components in the water drops quickly after they are dissolved,” Goka said. “But such components long remain in the soil. Nymphs at the bottom of water could have been affected.” Dr. Goka is calling for more testing […]

(Beyond Pesticides, March 31, 2016) On Tuesday, Terminix International LP and its U.S. Virgin Islands (USVI) operation agreed to a $10 million plea agreement after being  charged by the U.S. Justice Department and Environmental Protection Agency (EPA)  in U.S. District Court with multiple violations of the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) for “illegally applying fumigants containing methyl bromide in multiple residential locations in the U.S. Virgin Islands.” This decision by Terminix to pay criminal fines comes just one year after a Delaware family of four was poisoned with the neurotoxic pesticide at a resort in St. John, resulting in hospitalization and serious injury. The agreement, which is still subject to District Court approval, requires Terminix USVI to pay $6 million in fines and restitution to EPA for response and clean-up costs, and Terminix LP to pay $3 million in fines and fund a $1 million community service project, and a probation period of three years. In addition, Terminix LP is also responsible for resolving past and future medical expenses for the family through separate civil proceedings. Last March, a family from Delaware was vacationing at a  luxury condo in the U.S. Virgin Islands when they were exposed to […]

(Beyond Pesticides, March 28, 2016) In the first test of a landmark beekeeper compensation law that works to protect beekeepers from the effects of toxic pesticides on their hives, Minnesota has recently compensated two beekeepers for pesticide drift that killed their bees. Investigators from the Minnesota Department of Agriculture (MDA) have confirmed what beekeepers and environmentalists have been saying: Even when pesticides are used in accordance with the label and the law, they can be acutely toxic to bees in everyday circumstances. Pam Arnold, an organic farmer who manages hives on her property, and Kristy Allen, another beekeeper who shares the same bee yard, were the first two beekeepers to actually receive compensation through the beekeeper compensation law. Last spring, a farmer across their road planted neonicotinoid (neonic) coated corn seeds on a windy day, resulting in the death of their bees as toxic dust from planting drifted on to their property. Tests performed by MDA during the investigation found acute levels of clothianidin in the dead bees, even days after the incident. Nearby dandelion weeds also showed significantly higher concentrations of the toxin. According to the MDA website, the case closing letter was sent in November 2015, but they […]

(Beyond Pesticides, March 25, 2016) Glyphosate is found to contaminate California wines, according to a new report from the non-profit group Moms Across America. Glyphosate is pervasive and toxic chemical found in Monsanto’s Roundup weedkiller and was classified in 2015  as a probable carcinogen  by the International Agency for Research on Cancer (IARC). The report finds that all of the ten wines tested positive for glyphosate. The highest level of glyphosate detected was nearly 30 times higher (at 18.74 parts-per-billion, or ppb) than other wines from a 2013 Cabernet Sauvignon  sourced from a conventional, chemically farmed vineyard. The lowest level (.659 ppb) was from a biodynamic and organic vineyard, a 2013 Syrah. According to the owner, the vineyard has never been sprayed, indicating the possibility of pesticide drift from conventional agriculture, which has been a real and persistent problem for organic growers. EPA has done little to protect organic growers, who often bear the burden, both economic and otherwise, of pesticides applied to nearby conventional farmlands and vineyards. The report also points out that “the detection of glyphosate is an indicator of the presence of many other co-formulants in glyphosate-based herbicides, which have recently been shown”¦to be endocrine hormone disruptors […]

(Beyond Pesticides, March 24, 2016) This week, four major food manufacturing companies, Kellogg’s, General Mills, Mars, and ConAgra, committed to labeling food containing genetically engineered (GE) ingredients, while exclaiming the safety of GE food. Each company released statements citing the new Vermont labeling law, set to take effect this summer. The four companies joined Campbell Soup Company, which announced its  own label on GE ingredients in January. At the time,  Agri-Pulse reported, “Campbell made clear that it still supported the use of genetic engineering in agriculture, but said that there is a need for national labeling standards that would preempt state standards.” A summary of the companies’  releases are as follows: Kellogg’s Kellogg’s North America President, Paul Norman, insists upon the adoption of a “federal solution for the labeling of GMOs.” Until that happens, he says, “We will start labeling some of our products nationwide for the presence of  GMOs beginning in mid-to-late April. We chose nationwide labeling because a special label for Vermont would be logistically unmanageable and even more costly for us and our consumers.” In addition to a label, Kellogg’s launched OpenForBreakfast.com, which invites consumers to ask questions and learn more about products that include GE ingredients. […]

(Beyond Pesticides March 23, 2016) Last week, the Vermont House of Representatives passed a bill that authorizes state  regulation of pesticide-treated products,  including  telephone poles and coated seeds, that are exempt from federal pesticide regulations. H.861 is the latest in a string of laws introduced this legislative session in Vermont to address the impact of harmful neonicotinoid insecticides  on Vermont’s ecology and agriculture, and symbolizes a concentrated effort by the legislature to reverse pollinator declines within the state. If passed by the Senate and signed by the governor, the bill will  allow the Secretary of Agriculture to regulate above and beyond current federal laws, which exempt treated articles from regulation completely, and write appropriate rules in response to recommendations from a state Pollinator Protection Committee. The bill, which passed with wide support in the House, gives the Vermont Agency of Agriculture, Food and Markets the authority to regulate “treated articles,” a term coined by the Environmental Protection Agency (EPA) to denote products treated with pesticides, such as utility poles, commercial crop seeds, and lumber. Traditionally, EPA gives rulemaking authority over pesticides to states, but that authority does not extend to products pre-treated with pesticides, which, until this point, has posed […]

(Beyond Pesticides, March 16, 2016) Another study, this time from researchers at the University of Guelph, finds that at very low levels the neonicotinoid pesticide thiamethoxam affects  the foraging behavior of bumble bees, changing their floral preferences, hindering their ability to learn and extract nectar and pollen. This study is one of many that detail the negative effects of pesticides on bees’ learning behavior and ability to pollinate essential crops. Pesticides, like the neonicotinoid class of insecticides, have been implicated in the global decline of pollinator populations, while advocates call for  limiting pesticide exposures to reverse population declines. According to the authors of this Canadian study, “Chronic exposure to a neonicotinoid pesticide alters the interaction between bumblebees and wild plants, “published in  the journal Functional Ecology, it is the first to explore how pesticides may impact the ability of bumble bees to  forage from common wildflowers that have complex shapes such as white clover and bird’s foot trefoil. The researchers found that bumble bees exposed to environmental levels of thiamethoxam (10ppb) took longer to collect pollen than unexposed bees, as well as foraged from different flowers. Importantly, this study reports that bumble bees that were not exposed to thiamethoxam are […]

(Beyond Pesticides, March 15, 2016) Executive agencies are falling short in their efforts to protect honey bees and other wild pollinators from catastrophic declines, according to a new report from the U.S. Government Accountability Office (GAO). GAO, an investigative agency that works on behalf of the U.S. Congress, was tasked by the Senate to evaluate the progress the Environmental Protection Agency (EPA) and U.S. Department of Agriculture (USDA) have made in their actions to address the multiple threats contributing to declining managed and wild pollinators. Since 2006, U.S. beekeepers have experienced unsustainable colony die-offs, averaging over 30% each year. Concurrent declines in wild and native pollinators are also occurring, though data on the magnitude of these losses have not undergone comprehensive scientific evaluation. While a range of factors, from habitat loss, to climate change, diseases, viruses, and parasites are all contributing to these declines, independent science has identified that pesticides, specifically a new class of systemic insecticides called neonicotinoids, are the major drivers of the crisis for both managed and wild bees. In fact, some studies show that the widespread exposure to neonicotinoids increases bees’ vulnerability to diseases, viruses, and mites. The GAO report recommends a number of action items […]

(Beyond Pesticides, March 11, 2016)  A judge found a Colorado rancher to be in violation of a court order that protected his neighbors, organic farmers Rosemary Bilchak and her husband Gordon MacAlpine, who suffers from leukemia, from sprayed pesticides that drifted onto their property. The decision in western Colorado’s North Fork Valley sets a precedent in protecting farmers and sensitive people from pesticides.  State Judge Jeff Herron sentenced Hopper to jail for two days ””and fined him $7,500 ”” ruling that his spraying until 2015  violated a 2012 court order  that protected his neighbors. Despite this court order, records say Mr. Hopper continued spraying through August 2015. Mr. Hopper had obtained a state license to spray pesticides in 2011 after his wife was diagnosed with West Nile virus, which is spread by mosquitoes. However, Mr. Hopper’s neighbors took him to court, claiming the pesticides were harmful to Mr. MacAlpine’s health and prevented them from expanding into organic vegetable production. The presiding judge at the time of the 2012 court ruling, Charles Greenacre, determined that an application of the insecticide, Fyfanon, a form of  malathion, had drifted, and thus trespassed, onto the neighboring organic farm of Rosemary Bilchak and her husband, […]

(Beyond Pesticides, March 10, 2016) Jonathan Lundgren, Ph.D., a top U.S. Department of Agriculture (USDA) entomologist who received a prestigious national award for civic courage  for his work on neonicotinoids and pollinator decline in the face of agency attempts to suppress his work, will be speaking at Cultivating Community and Environmental Health, the 34th National Pesticide Forum, April 15-16, 2016 in Portland, ME. Dr. Lundgren will join other top scientists and leaders who have stood up to protect human and environmental health, despite facing industry backlash and scientific suppression. His story was recently featured in Sunday’s The Washington Post Magazine, Was a USDA Scientist Muzzled Because of His Bee Research, as censorship of federal scientists has grown. As a Senior Research Entomologist and Lab Supervisor for the Agricultural Research Service (ARS) in South Dakota, Dr. Lundgren had worked for USDA for eleven years with great success, with his research drawing national attention and international recognition. However, in October 2015, Dr. Lundgren, represented by Public Employees for Environmental Responsibility (PEER) filed a whistleblower complaint charging the agency with suppression of research findings that challenged the safety and efficacy of a widely used class of pesticides, neonicotinoids. In April 2015, PEER filed […]

(Beyond Pesticides March 9, 2016) Last week, Senators Jeff Merkley (OR), Patrick Leahy (D-VT), Jon Tester (D-MT), and Dianne Feinstein (D-CA) introduced legislation to  require  that consumer food packaging  displays genetically engineered (GE) ingredient labeling. The Senators’ legislation, the Biotechnology Food Labeling and Uniformity Act  (S.2621), presents an alternative to the primarily Republican-backed Biotechnology Labeling Solutions Bill that recently passed the Senate Agriculture Committee on a 14-6 vote. The Biotechnology Labeling Solutions Bill, which embodies several provisions of the much opposed DARK Act, will  hide ingredient information from consumers by overturning state GE labeling laws like that of Vermont’s. “Rather than blocking consumers’ access to information they want, the U.S. Senate should move forward with a solution that works for businesses and consumers alike,” said Senator Merkley. “There is a way to give consumers the information they are asking for without placing unfair or conflicting requirements on food producers. This legislation provides the common-sense pathway forward.” The  Biotechnology Food Labeling and Uniformity Act  will allow American consumers to see whether a food has been prepared with GE ingredients, while offering food manufacturers several options for including this information on or near the ingredients list. This framework meets the needs of […]

(Beyond Pesticides, March 8, 2016) A vast majority of German citizens are contaminated with the herbicide glyphosate, according to a report from the Heinrich Boll Foundation. The findings come just one week after another environmental group in Germany, the Munich Environmental Institute, found traces of the popular weed killer in popular German beers. The results of this study add concern to EU-wide deliberations regarding the renewal of glyphosate’s registration. According to the study, 99.6% of the 2,009 German citizens monitored have some level of glyphosate found in their urine. Over 75% of these individuals have  concentrations that are higher than the EU’s legal level for glyphosate in drinking water. Further, children up to age 19 are found to exhibit  higher levels of urinary glyphosate than older adults. Individuals living near agricultural areas also show elevated concentrations compared to those that did not. Given recent data finding glyphosate to be the most widely used herbicide on the globe, it is not surprising that the chemical is near ubiquitous in human bodies. Similar results are expected in the United States. A pilot study conducted by the group Moms Across America in 2014 found that glyphosate may also bioaccumulate in the human body, […]

(Beyond Pesticides, March 7, 2016) A United Nation’s report, released late last month, has warns the world that many species of wild bees, butterflies and other pollinators are on a dangerous path toward extinction, and that the  food supply will suffer if the causes of these declines, many of them human-made, are not stopped. The report is based on  many different scientific studies. The scientists who led the assessment pointed to pesticides as one of the leading causes of pollinator decline, specifically, a class of toxic chemicals called neonicotinoids, which adversely affect the nervous system of insects. According to their press release, the assessment,  Thematic Assessment of Pollinators, Pollination and Food Production, is the first ever issued by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem  Services (IPBES). IPBES was founded in 2012 with 124 member nations to “form a crucial intersection between international scientific understanding and public policy making.” Before its release, the assessment attracted some controversy for including two representatives from the agrochemical industry, including Bayer CropScience and Syngenta, as lead authors. Even though the IPBES requires all lead authors to complete conflict-of-interest statements, some scientists and environmentalists expressed concern. Given the roll of agrochemicals in pollinator decline, […]

(Beyond Pesticides, March 4, 2016) Honey bees experience a learning and memory deficit after ingesting small doses of the insecticide  chlorpyrifos, potentially threatening their success and survival, according to a study in  New Zealand. Chlorpyrifos is a highly neurotoxic organophosphate pesticide used worldwide on crops to protect against insects and mites. The study,  Measurements of Chlorpyrifos Levels in Forager Bees and Comparison with Levels that Disrupt Honey Bee Odor-Mediated Learning Under Laboratory Conditions,  published in  Ecology, examines chlorpyrifos levels in  bees collected from 17 locations in Otago, New Zealand and compared doses of the pesticide that cause sub-lethal effects on learning performance under laboratory conditions with amounts of chlorpyrifos detected in bees in the field. Researchers found chlorpyrifos in 17% of the sites sampled and 12% of the colonies examined. Honey bees are found to experience harmful effects to smell memory and learning, and reduction in specificity of memory recall. Chlorpyrifos is just one of many pesticides that have frequently been detected in honey bees. According to a study conducted last year by the U.S. Geological Survey (USGS), 72% of bees tested positive for pesticide residues, raising concerns about  unintended pesticide exposures where land uses overlap or are in proximity […]
