(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 â 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 âneonicotinoids. A new report released by Friends of the Earth, analyzes plants purchased at  Home Depot,  Loweâs, 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, 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 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, âNeonicotinoid-contaminated pollinator strips adjacent to cropland reduce honey bee nutritional status,â 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. âThe 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,â said Charles Hatt, staff lawyer at Ecojustice. Under Canadaâs Pest Control Products Act, PMRA must have âreasonable certaintyâ 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, June 23, 2016) A truck full of dead bees made its final stop yesterday at a rally outside the headquarters of the U.S. Environmental Protection Agency (EPA), culminating a coast-to-coast tour to raise awareness about recent massive declines in pollinators. While the millions of dead bees stayed on the truck, advocates and beekeepers, including Beyond Pesticides, delivered over 4 million signatures urging an immediate ban on bee-killing pesticides. âIn the five years since I started keeping bees, Iâve seen many hives killed by pesticides,â said James Cook, a Minnesota-based beekeeper who has been driving the truck across the country since last Monday. âIf some fundamental things donât change, itâs going to be really hard for beekeepers to adapt to the environment around us.â Bees pollinate most of the worldâs most common crops, including summer favorites like peaches and watermelon. But over 40 percent of U.S. honeybee hives die each year, costing the farming and beekeeping industry more than $2 billion annually. The most significant culprit in the bee die-off is the widely-used class of pesticides called neonicotinoids, or neonics. Last spring EPA began a process to assess four types of neonics and their impacts on pollinators. In January […]

(Beyond Pesticides June 20, 2016) As the end of the school year approaches, two first grade classrooms at local District of Columbia Public Schools (DCPS) got to learn about the importance of pollinators firsthand when DC-based nonprofit Beyond Pesticides visited their school. In a lead up to National Pollinator Week, Beyond Pesticides teamed up with owner and founder of The Bees Waggle, Jessica Goldstrohm, to provide a fun, hands-on lesson about pollination, and why it is important to our food system. Students were given a lesson on biodiversity, soil health, and the negative effects of pesticides on pollinators before building some pollinator-friendly habitat for their schools and homes. The day of learning kicked off at Brightwood Education Campus, located in Northwest DC, where students listened to a lesson developed by Ms. Goldstrohm, who donned a set of bee wings for the event. After receiving some background on the role of pollinators in our food system, the children participated in several hands on activities that reiterated the key points within the curriculum. Six volunteers stepped to the front of the class to demonstrate the interconnectedness of all living organisms by participating in a biodiversity web simulation. Here, the scholars learned that […]

(Beyond Pesticides, June 17, 2016) The pesticide industry has weakened and delayed pesticide reforms and is shaping new state pollinator âprotectionâ plans nationwide that do little to protect bees, according to a new Friends of the Earth report.  The report is being released in advance of  Pollinator Week (June 20-26, 2016), as people assemble to ask for improved protection for pollinators. The investigation, Buzz Kill: How the Pesticide Industry is Clipping the Wings of Bee Protection Efforts Across the U.S., reveals an array of pesticide industry tactics to slow urgently needed pollinator protection measures at federal and state levels. The report details how new state pollinator protection plans, many still unfinished, have been heavily influenced by pesticide industry interests. According to the report, industry is spending hundreds of thousands of dollars on lobbying to delay state and federal action on the chemicals they manufacture. As a result, state pollinator protection plans across the U.S. are falling short in several ways, including: State pollinator protection plans currently provide more protections for pesticides and pesticide users than for bee keepers and bee colonies. Pesticide industry influence is pervasive throughout statesâ legislative and regulatory planning efforts. Plans lack metrics to measure effectiveness, improvement […]

(Beyond Pesticides, June 14, 2016) To celebrate National Pollinator Week, June 20-26, 2016, several Washington, DC restaurants have teamed up with Beyond Pesticides and the Center for Food Safety to launch a campaign, âMade by Pollinators,â to protect pollinators suffering steep declines. With one out of every three bites of food reliant on bees, the participating restaurantsâ patrons will be treated to a special menu featuring pollinator-friendly food and provided with information on what they can do to help pollinators. The restaurants hope to increase public awareness on the importance of pollinators and steps that can be taken to reverse the decline. Participating  restaurants include Busboys and Poets, Founding Farmers, Lavagna, the Tabard Inn and Restaurant Nora. Of the 100 crop varieties that provide 90% of the worldâs food, 71 are pollinated by bees. Honey bees alone pollinate 95 kinds of fruits, nuts and vegetables, such as apples, avocados, almonds, and cranberries. The value of pollination services to U.S. agriculture alone amounts to nearly $30 billion and about 80% of flowering plants require animal pollination. A recent government survey reports that U.S. beekeepers lost 44 percent of their colonies between spring 2015 and 2016 âthe second highest loss to date. […]

(Beyond Pesticides, June 10, 2016) A proposal for a temporary ‘technical extension’ of the EU approval of the herbicide glyphosate failed to secure the support of a majority of EU governments at a meeting of the EU standing committee on plants, animals, food and feed on Monday. This action may force the withdrawal of the herbicide, widely sold as Monsantoâs Roundup, from shelves if no decision is reached by the end of the month, when its license expires. After a proposal to renew the license for glyphosate for up to 15 years failed to win support in two meetings earlier this year, the EU executive offered a limited 12 to 18 month extension to allow time for further scientific study. Yet, despite this compromise, the proposal failed to win the support of member states representing at least 65% of the EUâs population, which is needed for adoption, an EU official told The Guardian. Seven member states abstained from Mondayâs vote, 20 backed the proposal and one voted against, a German environment ministry spokeswoman said. According to the news source, Germany was among those that abstained from Mondayâs vote. Of note is that Bayer, the German chemical company, recently offered to […]

(Beyond Pesticides, June 3, 2016) Despite recent reports of continuing bee losses across the U.S., the U.S. Environmental Protection Agency (EPA) has announced plans to reevaluate the use of the bee-toxic insecticide sulfoxaflor, and is proposing an amended registration. Sulfoxaflorâs initial 2013 registration was challenged by beekeepers and subsequently vacated by the Ninth Circuit Court of Appeals due to overwhelming risks to bees and EPAâs inadequate review of the data. Last September, the  Ninth Circuit Court of Appeals unequivocally rejected  EPAâs registration of sulfoxaflor. The Court concluded that EPA violated federal law when it approved sulfoxaflor without reliable studies regarding the impact that the insecticide may  have on honey bee colonies. The Court vacated EPAâs unconditional registration of the chemical, meaning that sulfoxaflor could no longer be used in the U.S. This decision was in response to a suit filed by beekeepers challenging EPAâs initial registration of sulfoxaflor, which cited the insecticideâs threat to bees and beekeeping. The case:  Pollinator Stewardship Council, American Honey Producers Association, National Honey Bee Advisory Board, American Beekeeping Federation, Thomas Smith, Bret Adee, Jeff Anderson v. U.S. EPA  (9th Circuit U.S. Court of Appeals,âÂŻNo. 13-7234) According to the court decision, EPA skirted its own regulations […]

(Beyond Pesticides June 2, 2016) United States Department of Agriculture (USDA) Secretary Tom Vilsack recently released a Proclamation for National Pollinator Week, which is set to take place from June 20-26, 2016. National Pollinator Week began ten years ago when the U.S. Senate unanimously approved the designation of a week in June to address the urgent issue of declining pollinator populations. Pollinator week has since grown to be an international celebration of the valuable ecosystem services provided by bees, birds, butterflies, bats and all other pollinator species. While much remains to be done to combat contributing factors to pollinator declines, such as the use of neonicotinoid pesticides and disappearing pollinator habitat, National Pollinator Week is a chance to reflect and celebrate the achievements of the past year, while simultaneously raising awareness of the important role pollinators play in our daily lives. This year, to help increase education and bring awareness to the issue of pollinator declines, Beyond Pesticides and the Center for Food Safety are teaming up with several Washington, DC area restaurants to launch a âMade by Pollinatorsâ campaign. Participating  restaurants, which include Founding Farmers, Lavagna, Tabard Inn and Restaurant Nora, will  educate the public on the importance of […]

(Beyond Pesticides, June 1, 2016) A study  by researchers at Purdue University has concluded  that honey bees collect most of their pollen from non-crop plants that are frequently contaminated with agricultural and urban pesticides. The researchers found this to be true even in places where croplands dominate the area.  The study, which detected neonicotinoids, pyrethroids, fungicides, and others, highlights the large number of toxic pesticides to which bees are exposed to in the environment. Researchers collected pollen from Indiana honey bee hives at three sites over 16 weeks. The hives were placed in a variety of settings, such as an open meadow with wildflowers, woody shrubs and trees present (non-agricultural), the border of a corn field that was treated with the neonicotinoid clothianidin and three fungicides, and the border of a non-treated corn field. The pollen samples that were collected by the bees represented up to 30 plant families and contained residues from pesticides spanning nine chemical classes. The researchers found 29 pesticides in pollen from the meadow site, 29 pesticides in pollen from the treated cornfield, and 31 pesticides in pollen from the untreated cornfield. The most common chemical products found in pollen from each site were fungicides and […]

(Beyond Pesticides, May 26, 2015) Marylandâs historic Pollinator Protection Act, (SB 198 and HB 211) may be in danger. Last month, lawmakers approved the bill by a 98-39 vote in the Maryland House of Delegates, however it faces the possibility of a veto by Governor Larry Hogan (R). While the governorâs office says that the bill is currently under review, according to local news source WBAL, the governor is prepared to veto the bill, which he has until tomorrow, Friday, May 27, to do. If the governor does veto the bill, Marylandâs Pollinator Protection Act will go back to the legislature for an override vote, which will take place in early 2017. Meanwhile, beekeepers continue to lose their bees at unprecedented rates. Last week, we reported results of 2015-16 Colony Loss Survey, which show no sign that the crisis of abating. According to the survey, beekeepers lost 28.1% of their colonies over this past winter, and a total of 44% of their colonies over the last year. This marks the second year in a row that summer declines (28.1%) were on par with declines experienced during winter. WBAL reports that the governor is likely to veto the bill because of […]

(Beyond Pesticides, May 17, 2016) It was 10 years ago that commercial beekeepers first reported widespread, unsustainable winter losses of their honey bee colonies. A decade after the alarm was first sounded on pollinator declines, results of 2015-16 Colony Loss Survey show no sign the crisis of abating. According to the Bee Informed Partnership survey, beekeepers lost 28.1% of their colonies over this past winter, and a total of 44% of their colonies over the last year. This marks the second year in a row that summer declines (28.1%) were on par with declines experienced during winter. Beekeepers factor in that a small percentage, <15% of their colonies, will be lost each winter, but do not expect to lose colonies during the summer, when there is amble forage and nectar for bees. The costs beekeepers must incur to keep their hives alive continue to increase. More time and money is spent to maintain their hives, yet losses continue to be staggering ââ and unsustainable. As colony collapse disorder (CCD), the cryptic loss of honey bee colonies with no sign of dead bees in or around the hive, has faded from public discussion, concerns over pollinator declines in general, from bees […]

(Beyond Pesticides, May 11, 2016) Another campus, Macalester College in St. Paul, Minnesota has pledged to become a designated BEE Protective campus. This recognition comes from Beyond Pesticidesâ and Center for Food Safetyâs BEE Protective Campaign, which aims to protect bees and other pollinators from harmful pesticides like neonicotinoids. As part of its  commitment, Macalester College will  no longer use neonicotinoids on its  campus grounds. Neonicotinoids are a class of pesticides known to have severe impacts on bee populations. Macalester is now one of several campuses around the country that have pledged to protect pollinators and move away from using harmful pesticides that are toxic to these beneficial creatures. Just last month,  Antioch College in Yellow Springs, Ohio pledged to become a BEE Protective campus. In addition to these campuses, several local communities and states are also taking a stand for pollinators by passing policies that restrict the use of bee-toxic pesticides. For more on how your campus or student group can support pollinators and become BEE Protective, visit the BEE Protective Ambassadors webpage. âMacalesterâs new resolution to help protect pollinators fits well with our Sustainability Plan and Sustainable Landscaping Master Plan.

(Beyond Pesticides, May 10, 2016) Following an apparent accidental release of documents relating to the safety of the herbicide glyphosate, late last month the U.S. Environmental Protection Agency (EPA) also released and then retracted a preliminary ecological risk assessment of another toxic herbicide, atrazine. Under federal law, every pesticide registered in the United States is required to undergo a 15-year registration review to analyze human health and environmental impacts and determine whether the chemicalâs use should continue another 15 years. The last decade and a half have seen plethora of studies underscoring that atrazine is harmful to human health, and poses unreasonable adverse risks to ecological health, despite attempts by its major manufacturer, Syngenta, to silence and discredit its critics. EPAâs preliminary ecological risk assessment finds that for current uses at prescribed label rates, atrazine may pose a chronic risk to fish, amphibians, and aquatic vertebrate animals. Where use is heavy, the agency indicates that chronic exposure through built-up concentrations in waterways is likely to adversely impact aquatic plant communities. Â Levels of concern, a wonky equation that EPA produces to measure risk, were exceeded for birds by 22x, fish by 62x, and mammals by 198x. Even reduced label rates were […]

(Beyond Pesticides, May 3, 2016) In a bipartisan victory for bees, last week the Connecticut House of Representatives unanimously (147-0) passed a wide-ranging bill aimed at protecting declining pollinator populations within the state from toxic neonicotinoid (neonic) pesticides. Bill No. 231, An Act Concerning Pollinator Health, was also passed unanimously (36-0) through the Connecticut State Senate on April 21, and now goes to Governor Dannel P Malloy for his signature. Earlier in April, both houses of the Maryland legislature passed the Maryland Pollinator Protection Act, which is currently awaiting action by Governor Larry Hogan (R). Connecticutâs bill addresses a broad range of concerns relating to pollinator health, from pesticides to parasites and habitat remediation, within both residential and agricultural settings. In summary, the bill does the following: Prohibits applying neonicotinoid insecticide (a) to linden or basswood trees or (b) labeled for treating plants, to any plants when such plant bears  blossoms; Bee health experts identified the application of systemic neonicotinoids to Tilia trees as a significant concern for pollinator health after a spate of massive bee-kill incidents on the west coast. In June 2013, over 50,000 bumblebees were killed after a neonic was applied to a linden trees in […]

(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 […]

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. âAt 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, âËIf we are not leaders in discovering and implementing  new and better ways of living  , then what is the point?ââ said Beth Bridgeman, the faculty member who drove the effort to ban neonicotinoids from campus.

(Beyond Pesticides, April 25, 2016) Last week, the City Council of Milwaukie, Oregon passed a resolution that halts the use of bee-toxic neonicotinoid insecticides on city government and public property,  joining the growing number of local governments protecting pollinators.  Neonicotinoids  (neonics) have been widely cited in the demise of both managed and wild bee and pollinator populations.  The resolution specifically  restricts city government agencies from purchasing plants and seeds that have been treated with neonicotinoids and other systemic insecticides and urges public and private landscapers and homeowners to plant bee-friendly habitats.  Clackamas County will join with the Mayor’s office and City Council of Milwaukie to adopt an Integrated Pest Management Plan that mirrors the resolution. In addition to these stipulations, the City of Milwaukie is using this resolution to: urge all businesses, homeowners, and homeowner’s associations operating within the City ensure no plants, seeds, or products containing neonicotinoids are purchased, sold, or used within the City; and to clearly and accurately label any plants or materials that have been treated with a neonicotinoid or neonicotinoid-like insecticide; require that commercial pest service providers performing services on behalf of the City provide landscape services that encourage pollinator populations and support pollinator services; […]
