(Beyond Pesticides, August 18, 2015) Research looking at corn production  across the Northern Great Plains finds that fields with lower insect biodiversity are at greater risk for pest problems, showing that insect diversity can reduce the need for pesticides, yet again highlighting the critical need for biodiversity in a resilient and sustainable food production system. The research article, Trading Biodiversity for Pest Problems, is published in the July 31 issue of Science Advances, and explores how current chemical-intensive  practices have resulted in altered pesticide use patterns, land use intensification, and landscape simplification, all of which threaten biodiversity in and near farms. The findings suggest that farming practices that promote insect biodiversity is  an effective way to control pests without the use of harmful pesticides. Scientists Jonathan Lundgren, PhD, an entomologist at the U.S. Department of Agriculture—Agricultural Research Service (USDA-ARS), and Scott Fausti, PhD, an economics professor at South Dakota State University looked at insect diversity in cornfields on 53 different eastern South Dakota farms. The researchers evaluate fields that do not use insecticides or crops that are genetically engineered (GE), which may  influence corn insect communities. They also specifically identify insect species during the time in the corn’s life cycle […]

(Beyond Pesticides, August 12 2015) Last week, the City of Plattsburgh, New York, unanimously approved a policy that encourages city departments and city residents to reduce and eventually eliminate their use of toxic pesticides, such as neonicotinoids and glyphosate. In the same resolution, city residents and department heads are also encouraged to refrain from genetically modified organism (GMO) cultivation, though they recognize there is very little of that taking place within Plattsburgh city limits. While this policy can only be used to discourage the use of pesticides and GMOs, not implement an outright ban, due to preemptive New York state law that occupies the field of pesticide regulation, city officials are hopeful that they will be able to use their influence to implore the state of New York and U.S. legislators to take statewide and nationwide measures on the production of GMO crops and to curb the use of toxic pesticides. The language of the resolution, sponsored by Councilman Mike Kelly, cites the health of honey bees and other insects as one of the main reasons for encouraging citizens to refrain from the use of pesticides in the practice of lawn care and beautification. It also specifically names neonicotinoids as […]

(Beyond Pesticides, August 5, 2015) The United Kingdom (UK) is poised to harvest higher than expected yields of winter oilseed rape (canola) in its first neonicotinoid-free growing season since the European moratorium on neonicotinoids went into place in 2013. This bumper harvest comes amid the recent approval of an emergency exemption for neonicotinoid use on the crop in certain areas of the UK, and disproves the industry argument  that  the crop would falter without the use of neonicotinoids. Activists argue that these findings show there is ”˜no emergency’ for neonicotinoid use and that the current moratorium should remain in effect. The first harvest results of winter oilseed rape (canola) planted without neonicotinoid seed treatments have come in – and farmers are experiencing a better than usual crop. Figures for the first oilseed rape harvest since the European-wide ban on neonicotinoid pesticides was introduced show that the yield so far is higher than the average for the previous decade, when the chemicals were used on the majority of oilseed rape grown in the UK. Farmers Weekly, a leading multimedia information service for farmers and agricultural businesses, has reported that yields are up by as much as eight percent. The European Union […]

(Beyond Pesticides, August 4, 2015) Nearly every food available for purchase at the U.S. Congressional Dining Hall contains detectable levels of neonicotinoids (neonics), chemical insecticides implicated in the global decline of wild and managed pollinators. The results of a new study, performed by the American Bird Conservancy (ABC) and the Harvard T.H. Chan School of Public Health, reveals how reliance on these toxic chemicals can both directly and indirectly affect  our food supply. Authors of the study hope the results will build Congressional support for the Saving America’s Pollinators Act of 2015, which would suspend the use of neonics while an independent review analyzes the chemical’s effects to birds, pollinators, and other wildlife. Researchers for the study conducted two rounds of food testing, the first in January, and the second in May 2015. Approximately half of samples were taken from the House Longworth Cafeteria and half from Senate Dirksen Cafeteria in Washington, D.C. In total, 66 food samples were tested for the presence of neonicotinoids. Of that, 60, or 91% of samples tested positive for one neonic, and 47, or 71% of samples had two or more neonics present. “We were surprised to find that most foods contained multiple neonicotinoids, […]

(Beyond Pesticides, July 28, 2015) Data published from the Harvard School of Public Health reveals  neonicotinoids (neonics), a class of chemicals implicated in the global decline of honey bees and other pollinators, in over 70% of both pollen and honey samples collected throughout the state of Massachusetts during months when bees are most actively foraging. The results of this study have grave  implications for pollinator health, as even minute, near-infinitesimal doses of neonics can cause sublethal impacts that compromise the health of entire bee colonies. The Harvard study, led by Chensheng (Alex) Lu, PhD, and published in the Journal of Environmental Chemistry, took monthly honey and pollen samples from 62 volunteered bee hives between April and August 2013. The 219 pollen and 53 honey samples were then analyzed for the presence of eight neonic insecticides. Every month, in every location, researchers found neonics in the pollen and honey collected by bees. In total, 73% of pollen samples and 72% of honey samples contained at least one neonicotinoid at levels which could result in sublethal harm. While previous studies have tested the presence of neonics at a single point in time, this is the first study to show the long-term persistence […]

(Beyond Pesticides, July 24, 2015) An emergency application was approved by the UK Department for Environment, Food, and Rural Affairs (DEFRA) on Wednesday that allows  farmers to use neonicotinoid seed treatment on 5 percent of oilseed rape crop (known as canola in the U.S.) this summer to control a flea beetle infestation. The emergency use, which has been granted for 120 days, allows growers to use Bayer CropScience’s Modesto (clothianidin) and Syngenta’s Cruiser OSR (thiamethoxam). The active ingredients of these products belong to a class of toxic chemicals knowns as neonicotinoids, which have been linked to pollinator decline. The request was the second one for the National Farmers Union (NFU) after the first request for a nationwide lifting of the two-year moratorium on neonicotinoid use was rejected. The NFU said it was “frustrated” at having to put in an application for a smaller area. There have been numerous attempts to shroud the application process in secrecy. DEFRA told its expert committee on pesticides (ECP) to halt its  normal practice of publishing the minutes  of meetings at which the neonicotinoid applications were discussed, in order to avoid “provoking representations from different interest groups.” Additionally, according to the Guardian, the UK government […]

(Beyond Pesticides, July 23, 2015) A recent study looks at the detrimental effects of neonicotinoids (neonics) on molluscan herbivores and their non-target insect predators, finding that slug exposure to neonics results in the secondary poisoning of beneficial predatory beetles. The study, authored by Maggie Douglas, PhD candidate at Penn State University, was presented earlier this month at a congressional briefing, An Expert Briefing to Discuss Pollinators and Efforts to Protect Them. The briefing was organized by Center for Food Safety and attended by the sponsors of Saving America’s Pollinators Act (H.R. 2692), Representatives John Conyers (D-MI) and Earl Blumenauer (D-OR). The study specifically looks at the pest slug Deroceras reticulatum and its predator beetle, Chlaenius tricolor. Ms. Douglas and her co-researchers find that neonicotinoid seed-treated soy beans can unintentionally impact predatory, beneficial insects through a previously unexplored pathway. Here are some highlights of the study’s methods and findings: Soy beans were treated with the neonicotinoid thiamethoxam. The seed treatments had zero effect on pest slugs, and instead were bioaccumulated and then transferred through the slugs into their insect predators, impairing or killing >60%. This resulted in a loss of crop due to a decline in beneficial insect predators and an […]

(Beyond Pesticides, July 13, 2015) Many factors have been identified in bee and other pollinator decline across the globe, including loss of habitat, disease, and pesticides. A  new study from researchers in North American and Europe finds that the  changing climate also plays a vital role in decreasing bee habitat and thus reducing populations. The study reports that North American and European bumble bees are unable to colonize new warmer habitats north of their historic range, while simultaneously disappearing from the southern portions of their range. Published in Science, the study,  Climate change impacts on bumblebees converge across continents,  which is a comprehensive look at 67 bumblebee species and their territories over the last century, finds that many North American and European bumblebees have retreated from the southern edge of their historic ranges (away from the equator). While other species of animals have been able to adapt to climate change by expanding their habitats, bumblebees have not shifted to warming northern climes and are experiencing shrinking distributions in the southern ends of their range. The rusty patched bumblebee (Bombus affinis), for instance, has disappeared from parts of the southeastern U.S. Bumblebees are also retreating to higher elevations, shifting upward by […]

(Beyond Pesticides, June 29, 2015) A recent study has provided supporting evidence to previous work showing that sublethal doses of imidicloprid, a toxic neonicotinoid insecticide, impairs olfactory learning in exposed honey bee workers. Since 2006, honey bees and other pollinators in the U.S. and throughout the world have experienced ongoing and rapid population declines. The science has become increasingly clear that pesticides (especially the neonicotinoid class of insecticides), either acting individually or synergistically, play a critical role in the ongoing decline of honey bees and wild pollinators. Neonicotinoids can be persistent in the environment, and have the ability to translocate into the pollen and nectar of treated plants. “Honeybees need to learn to associate nectar reward with floral odor. One of the main reasons why flowers produce odor is so that this odor can be learned by pollinators and used to repeatedly visit the same flower species. Without this repeat visitation, pollination does not occur. We showed that a neonicotinoid pesticide, at sublethal doses, harms this odor memory formation,”  Chinese Academy of Science’s Ken Tan, who led the study, told CBS News in an email interview. Published in Nature on June 18, 2015, the study finds that “adults that ingested […]

(Beyond Pesticides, June 22, 2015) Two new studies raise concerns over the connection between the use of fungicides and the declining overall health of bee colonies. While  the use of neonicotinoid insecticides has been established as a  primary contributor  to declining pollinator populations, these new studies shine a light on the use of fungicides and the negative impacts their use has on overall bee health. The first study was performed after a group of local farmers asked researchers at the University of Wisconsin to assess whether it was safe to spray fungicides on crops while they are in bloom and bees are foraging. Because insecticides, like neonicotinoids, are meant to kill insects, researchers have performed numerous studies on how the use of these insecticides may harm beneficial insects as well as those they are intended to target. Fungicides, however, are not meant to kill insects, so the relationship between their use and effects on bee populations is relatively unstudied. Researcher Hannah Gaines Day, Ph.D., an entomologist at the University of Wisconsin, cautions that her team’s study, which involved five bumblebee colonies kept in field enclosures where flowers were sprayed with field-realistic doses of chlorothalonil, a  common fungicide, was small and […]

(Beyond Pesticides, June 11, 2015) On July 1, Ontario will become the first jurisdiction in North America to officially begin reducing the number of acres planted with neonicotinoid-coated corn and soybean seeds, an action that has been in the making since 2014. The new rules should curb the acreage planted with such seeds by 80 percent by 2017. The new rules will be put in place to track the sale and use of neonicotinoid-treated seeds. Additionally, for the upcoming farming season, farmers will only be allowed to use the seeds on up to 50 percent of their corn and soybean fields. Exemptions are granted only to those who can provide evidence of pest problems. In 2017, any farmer who wants to use neonicotinoid-treated seeds will have to prove the presence of  pests. “Farmers are environmental stewards of their land and this regulation will enable our province’s farmers to strengthen their approach to protecting their crops,” Agricultural Minister Jeff Leal said in a statement Tuesday. Environment and Climate Change Minister Glen Murray said the government must take “necessary action to protect these vitally important species and the ecosystems they support from the effects of neurotoxic neonicotinoids.” Tibor Szabo, president of the […]

(Beyond Pesticides, June 9, 2015) Agricultural pesticides are sprayed intensively throughout the growing season in New York’s conventional apple orchards. Researchers at Cornell University found that as the use of pesticides on these farms increased, the abundance of wild bees declined significantly. The study, published in the Proceedings of the Royal Society B, focuses on the effects of conventional pesticide use on wild bees, which have often been overlooked in the midst of an ongoing crisis with managed honey bee colonies. “Because production of our most nutritious foods, including many fruits, vegetables and even oils, rely on animal pollination, there is an intimate tie between pollinator and human well-being,” said Mia Park, an assistant professor at the University of North Dakota and the paper’s first author, who worked on the study as a Cornell entomology PhD graduate student. Ms. Park and her colleagues analyzed wild bee populations on 19 apples orchards across the state of New York between 2011 and 2012. Data was broken down by class of pesticide (fungicide, insecticide, herbicides), and timing of applications (before, during, and after flower bloom). Researchers also analyzed the percentage of natural areas within the surrounding landscape. The study uncovered a number of […]

(Beyond Pesticides, June 1, 2015) Last week, the Environmental Protection Agency (EPA) released a proposal intended to create “physical and temporal space” between bees and toxic pesticides. While touted as monumental progress on bee health by the agency, the reality is that the proposal will only result in modest changes to pesticide labels. EPA’s new rules contain only a temporary ban on foliar applications of acutely bee-toxic pesticide products, including neonicotinoid class insecticides, during bloom and when a beekeeper is on site and under contract. The proposal doesn’t address the widespread contamination and detrimental effects of these toxic, systemic (whole plant poisons) chemicals that will continue to occur even during the temporary prohibition. Media reports have generally overstated the implications of the proposal, applauding the “new” restrictions, and labeling the small portion of agricultural land that is affected  as “pesticide-free zones,” which couldn’t be further from the truth. The restrictions are not anything new — EPA pesticide labels already prohibit applications while in bloom where bees are foraging. Neal Bergman, a commercial beekeeper in Missouri, said in a statement to the St. Louis Post-Dispatch that the proposal is “basically enforcing label guidelines,” further highlighting the fact that EPA has failed […]

(Beyond Pesticides, May 29, 2015) A report released by the Canadian Senate’s Committee on Agriculture and Forestry this week acknowledges that neonicotinoids are harmful to bees, although it adds that more scientific data is needed before making any policies in response. The report was released exactly one week after a similar announcement by the White House, which also identifies key threats, but falls short of recommendations submitted by Beyond Pesticides, beekeepers, and others who stress that pollinator protection begins with strong regulatory action and suspension of bee-toxic pesticides. The Canadian report, titled “The Importance of Bee Health to Sustainable Food Production in Canada,” highlights different stressors that cause harm to bees, one of which includes neonicotinoids, a class of widely-used insecticides that have been linked by a growing number of studies to global bee declines. Other stressors mentioned include climate change, diseases and parasites, and lack of floral diversity. The report calls for Canada’s Pest Management Regulatory Agency (PMRA) to quickly complete its re-evaluation of neonicotinoid pesticides. Neonicotinoids have been approved for use in Canada for 10 years, but the PMRA is in the process of re-examining their use. Senator Percy Mockler, the chair of Senate’s agriculture committee, stressed waiting […]

(Beyond Pesticides, May 27, 2015) As summer approaches, local stores continue to set the pace for protecting pollinator populations from the harms of neonicotinoid pesticide use. In southern Maine, Kittery Ace Hardware joins Eldredge Lumber and Hardware in its efforts to actively seek alternatives to  pesticides that contain  neonicotinoids and other toxic pesticides by consciously stocking their shelves with organic compatible products as opposed to lawn and garden products that contain toxic chemicals. This shift by local stores like Eldredge and Kittery highlights the role retailers can play in responding to community concerns over dangerous pesticide use, and indicates their desire to be part of the solution when it comes to protecting pollinators. Local stores’ increasing  attention to local concerns over a common problem is  juxtaposed with  big box hardware stores’ response to neonicotinoid concerns that respond to public pressure with vague language, drawn out or nonexistent timelines, and failure to take a stance on overwhelming scientific evidence that neonicotinoids cause harm to pollinator populations. As more national retailers respond to public pressure to ban neonicotinoid-containing products, it becomes clear that local, small-scale efforts to stock shelves with alternative products offer a better and more concrete approach to stopping neonicotinoid […]

(Beyond Pesticides, May 26, 2015) A study led by Purdue University Entomology Professor Michael Scharf, Ph.D. finds that small doses of imidacloprid, a neonicotinoid pesticide, can halt the normal functioning of termite behavior, leaving colonies vulnerable to disease and eventual death. While this effect may be celebrated by the pesticide industry as a victory for termite control, it has serious implications for the use of imidacloprid and other neonicotinoid pesticides on all eusocial insects, such as ants and bees. Eusocial insects thrive as a colony, working, living and sometimes even fighting diseases as one organism, rather than as many individuals existing together. Termites, specifically, exhibit a remarkable resistance to many diseases because they engage in social grooming, clearing pathogens off of one another. Other examples of eusociality can be found in ant and bee colonies. Ant colonies create foraging trails and engage in cooperative transport, where they create long chains of ant individuals to form a whole assembly line to transport food back to the colony and work as one to carry large prey that would not be otherwise attainable. Honeybee colonies send out foragers to report back with the location of plentiful food sources so that other bees know […]

(Beyond Pesticides, May 14, 2015) For the first time on record, summer losses of managed honey bee colonies have exceeded winter losses, according to preliminary results of the annual survey released yesterday by the Bee Informed Partnership, the U.S. Department of Agriculture (USDA) and the Apiary Inspectors of America. This is the second highest annual loss recorded to date: beekeepers lost a total of 42.1 percent of the number of colonies managed over the last year (total annual loss, between April 2014 and April 2015), which is up from 34.2 percent for the previous year. On the same day that this survey was released, the  U.S.  House Agriculture Subcommittee on Horticulture, Biotechnology and Research held a hearing on pollinator health, but failed to advance policy solutions that would protect pollinators from the unnecessary use of pesticides. “What we’re seeing with this bee problem is just a loud signal that there’s some bad things happening with our agro-ecosystems,” Keith Delaplane, PhD at the University of Georgia and one of the co-authors of the study told Phys.Org. “We just happen to notice it with the honeybee because they are so easy to count.” About two-thirds of the beekeepers responding to the survey […]

(Beyond Pesticides, May 8, 2015) A diverse group of environmentalists, beekeepers, farm workers, and advocates, along with Beyond Pesticides, sent a letter to the U.S. Department of Agriculture (USDA) Inspector General and the co-chairs of the White House Task Force on Pollinator Health this Tuesday, urging a thorough investigation into recent reports that USDA scientists are being harassed and censored. The letter expresses particular concern over the suppression of research related to bee-killing neonicotinoid insecticides and glyphosate, a key ingredient in Monsanto’s Roundup, which has been linked to cancer. The White House Task Force on Pollinator Health, co-chaired by USDA, is expected to release a plan on bee protection in the near future; the more than 25 groups, which include farmers, fisheries, and food safety advocates, are concerned that the plan will lack meaningful protections if USDA’s research has been compromised. In March, the Public Employees for Environmental Responsibility Group (PEER), an advocacy group for government researchers, filed a petition for rule-making with USDA seeking new rules to strengthen USDA’s Scientific Integrity Policy, and urging the agency to adopt best practices used in other federal agencies in order to prevent political suppression or alteration of studies. USDA adopted a new […]

(Beyond Pesticides, May 6, 2015) The City of Boulder, Colorado yesterday became the most recent locality in the U.S. to restrict the use of bee-toxic neonicotinoid (neonic) pesticides  on city property. The resolution moved forward primarily as a result of efforts by grassroots activists with the local organization Bee Safe Boulder, but also received strong support from city officials. “We at Bee Safe Boulder, along with city staff and elected city council members, believe that this resolution will become the go-to template for other local governments with similar aspirations in the near future,” said David Wheeler, co-founder of the local group. Under the new resolution, Boulder has committed to: Not applying neonicotinoid pesticides to city property; Encouraging “all related parties,” including county, state, and federal governments and private individuals to suspend their use of neonicotinoids until a thorough review is completed and a public health and environmental assessment can prove their safety; Seeking out plants and seeds not treated with neonicotinoids, and encouraging all businesses, homeowners, and HOAs within the city to make efforts to ensure no neonic-containing products are sold or used within the city; Engaging in efforts to educate the broader community about reducing neonicotinoid pesticides, and encouraging […]

(Beyond Pesticides, May 5, 2015) In a major  victory for the environment and health, the Washington state Department of Ecology (Ecology) and oyster growers association agreed to withdraw a permit allowing the use of the neonicotinoid insecticide imidacloprid to control burrowing shrimp in oyster beds in Willapa Bay and Grays Harbor. The decision was reached in large part due to vocal public outrage over the plan, as consumers, environmental organizations, and prominent local chefs spoke out against the spraying. “One of our agency’s goals is to reduce toxics in our environment,” said Ecology Director Maia Bellon in a News Release published by the agency over the weekend. “We’ve heard loud and clear from people across Washington that this permit didn’t meet their expectations, and we respect the growers’ response.” In an article published in the Seattle Times Friday, the largest shellfish producer in country, Taylor Shellfish, announced it will not treat its oyster beds with imidacloprid in response to numerous calls, emails, and social media comments made by its customers. “Our customers spoke loud and clear today, and that speaks volumes to us,” said Bill Dewey, spokesman for Taylor Shellfish. Given Taylor Shellfish’s size, it is likely that the Willapa/Grays […]

(Beyond Pesticides, May 4, 2015) Beekeepers, farmworkers, environmental and consumer groups last week  sent a letter,  signed by over 200,000 Americans, urging Michelle Obama to publicly commit to ensuring the White House gardens and grounds are free of dangerous neonicotinoid pesticides. The letter also asks that the First Lady use her influence to encourage the Obama administration’s  White House Pollinator Health Task Force (Task Force)  to take a strong stand against these bee-toxic pesticides. More specifically, the letter urges Mrs. Obama to follow the guidelines outlined by the Council on Environmental Quality in October of last year by publicly pledging to eliminate systemic insecticides from the White House gardens and grounds, including not sourcing plants pre-treated with these pesticides. In a memorandum announced in the summer of 2014, President Obama called forth the heads of executive departments to create a federal strategy promoting the health and safety of honey bees and other pollinators. The memorandum directed federal agencies to establish the Task Force to develop a pollinator health strategy within 180 days, and support and create pollinator habitat. This federal strategy included a pollinator research action plan, with a focus on preventing and recovering from pollinator losses, including studying how […]

(Beyond Pesticides, April 29, 2015) Much to the dismay of activists and concerned local residents, the Washington Department of Ecology (Ecology) approved a permit for the use of imidacloprid (a neonicotinoid) to combat a growing native population of burrowing shrimp that threatens valuable shellfish (oyster) beds in Willapa Bay and Grays Harbor in Washington state. Imidacloprid is known to be toxic to bees but is also toxic to aquatic organisms, raising questions on the impacts of its use on the long-term ecological health of the bays. The shellfish industry is important to the Pacific Northwest, injecting an estimated $270 million or more into the region’s economy, and providing jobs for many. Washington’s tidelands, especially those in Willapa Bay, have been particularly productive for more than 100 years. However, according to shellfish growers, the burrowing shrimp (ghost shrimp, Neotrypaea californiensis,  and mud shrimp, Upogebia pugettensis) undermines the industry. The creatures burrow into shellfish beds, making the beds too soft for shellfish cultivation. Their burrowing churns the tidelands into a sticky muck, smothering the oysters. After several years of deliberations and studies, Ecology identified imidacloprid as its  preferred choice for eradicating the shrimp. According to the agency, imidacloprid disrupts the burrowing shrimps’ […]

(Beyond Pesticides, April 24, 2015) Two new studies reporting on the adverse effects of neonicotinoids on bees were published Wednesday in the journal Nature, adding to a growing body of scientific literature linking the controversial class of pesticides to the global decline in bee populations. The conclusions reached by the two studies find that not only does neonicotinoid exposure result in reduced bee density, nesting, colony growth, and reproduction, but also that bees in fact prefer foods containing neonicotinoid pesticides despite their adverse effects. Neonicotinoids affect the central nervous system of insects, resulting in paralysis and eventual death. These pesticides have consistently been implicated as a key issue in pollinator declines, not only through immediate bee deaths, but also through sublethal exposure that causes  changes in bee reproduction, navigation, and foraging. The science has become increasingly clear that pesticides, either working individually or synergistically, play a critical role in the ongoing decline of honey bees. Pesticide exposure can impair both detoxification mechanisms and immune responses, rendering bees more susceptible to viruses, parasites, and other diseases, and leading to devastating bee losses. In one study, “Seed coating with a neonicotinoid insecticide negatively affects wild bees,” Swedish scientists report that wild bees […]
