(Beyond Pesticides, September 6, 2011) Scientists in France have discovered that honey bees are at a higher risk of dying from infection by Nosema ceranae (N. ceranae) when they are exposed to low doses of insecticides. The results, presented in the journal PLoS ONE, support the theory that combining more N. ceranae with high pesticide content in beehives could contribute to colony depopulation. The French study, “Exposure to Sublethal Doses of Fipronil and Thiacloprid Highly Increases Mortality of Honeybees Previously Infected by Nosema ceranae,” brought together researchers from the Laboratoire Microorganismes: GĂ©nome et Environnment and the Laboratoire de Toxicologie Environnment who utilized their respective skills in parasitology and toxicology to assess the effect of pathogen/toxin interactions on bee health. In the laboratory, the researchers chronically exposed newly emerged honey bees, some healthy and others infected with Nosema ceranae, to low doses of insecticides: fipronil and thiacloprid. They found that the infected bees died when they were chronically exposed to insecticides, even at sublethal doses, unlike the healthy bees. This combined effect on honeybee mortality was observed with daily exposure to extremely low doses (over 100 times less than the LD50 or dose needed to kill 50% of the sample population, […]

(Beyond Pesticides, August 1, 2011) After sighting three Japanese beetles in the vicinity of Greenback Lane and Fair Oaks Boulevard in Sacramento County, California, state officials are scheduled to spray pesticides linked to cancer, reproductive and neurological effects. On August 2, the California Department of Food and Agriculture (CDFA) is scheduled to begin ground applications of carbaryl on fruit-bearing trees, and cyfluthrin on non-fruit-bearing trees and landscape plants in attempts to stave of attacks from the voracious Japanese beetle. Japanese beetles, a threat to turf grass as well as ornamental plants such as roses and cut flowers, have been detected in the Fair Oaks area, state officials said, but the ”˜infestation’ appears to be localized. To keep the ”˜infestation’ from spreading countywide, Juli Jensen, Acting Agricultural Commissioner, is urging residents in the area not to move plants or plant parts. The initial treatments will be directed at adult beetles and begins August 2 with applications of carbaryl on fruit-bearing trees, and cyfluthrin on non-fruit-bearing trees and landscape plants. Two weeks later, a second treatment will be applied and augmented by a granular imidacloprid to target grubs. The applications, to occur on approximately 100 properties, will be carried out by the […]

(Beyond Pesticides, July 1, 2011) The U.S. Environmental Protection Agency (EPA) has granted emergency approval for the use of the neonicotinoid pesticide dinotefuran to control brown marmorated stink bugs in seven eastern states. Dinotefuran is a member of the neonicotinoid family of systemic pesticides that is known to be highly toxic to bees and associated with Colony Collapse Disorder. The states of Delaware, Maryland, New Jersey, North Carolina, Pennsylvania, Virginia, and West Virginia had previously asked EPA for emergency approval of the pesticide due to a ballooning stink bug population. The short term emergency measure became effective June 24 and will expire on October 15 of this year. Dinotefuran is already approved by EPA for use on other crops, such as grapes, cotton, and some vegetables. The emergency approval relates to the pesticide’s use on orchard crops such as apples, pears, peaches, and nectarines, for which it has not previously been allowed. Growers of those crops will now be able to apply dinotefuran from the ground twice per season. The agency will allow a total of 29,000 orchard acres to be treated, which does not include applications to the previously approved crops. Under a controversial stipulation known as a Section […]

(Beyond Pesticides, June 15, 2011) This week’s release of the new Shopper’s Guide to Pesticides in Produce (Dirty Dozen/Clean 15) by the Environmental Working Group (EWG), which focuses on pesticide residues on conventional produce, highlights the importance of eating organic fruits and vegetables to minimize personal exposure to toxic pesticides. Beyond Pesticides’ Eating with a Conscience guide complements the EWG list, going beyond residues on food to examine the impacts of the pesticides used to grow conventional produce on the health of farmworkers and rural communities, water quality, honey bees and wildlife poisoning, and more. Both Beyond Pesticides and EWG encourage shoppers to choose organic food whenever possible. To create their seventh edition of the Shopper’s Guide, analysts at EWG synthesized data collected from the U.S. Department of Agriculture (USDA) and the Food and Drug Administration (FDA). Most samples are washed and peeled prior to being tested, so the rankings reflect the amounts of the chemicals likely present on the food when is it eaten. Apples, celery and strawberries top this year’s “Dirty Dozen” list. Making an appearance in the guide for the first time is the herb cilantro, which had never been tested by USDA until now. The data […]

(Beyond Pesticides, June 10, 2011) A report released jointly by the U.S. Department of Agriculture’s (USDA) Agricultural Research Service (ARS) and the Apiary Inspectors of America (AIA) shows that losses of honeybee populations over the 2010/2011 winter remained abnormally high, reflecting continuing damages attributed to colony collapse disorder (CCD). CCD, linked to a range of factors and agricultural chemicals, including systemic pesticides, has devastated bees and beekeepers around the country in recent years. According to the survey, 30% of managed honeybee colonies across the country were lost over the winter. Over the past five years, since the discovery of CCD, annual winter colony losses have hovered near the 30% mark. Similar loss percentages for the previous four years reflect this trend: 34% for the 2009/2010 winter, 29% for 2008/2009, 36% for 2007/2008, and 32% for 2006/2007. ARS entomologist Jeffrey Pettis, PhD, who helped to conduct the survey and has been the agency’s lead researcher on CCD heading up the USDA Bee Research Laboratory, said, “The lack of increase in losses is marginally encouraging in the sense that the problem does not appear to be getting worse for honey bees and beekeepers. But continued losses of this size put tremendous pressure […]

(Beyond Pesticides, May 5, 2011) Over 70 international organizations, including health and environmental groups, landscapers and farmers are proclaiming tomorrow, Friday, May 6, 2011, Lawn Pesticide Awareness Day in honor of Dr. June Irwin’s leading role in passage of North America’s first lawn pesticide ban in Hudson, Quebec, on May 6, 1991. “The town of Hudson, Quebec, and particularly the actions of June Irwin, M.D., have sent a clear signal to communities all across North America that the use of lawn and landscape pesticides is both harmful and unnecessary,” said Jay Feldman, the founder of Beyond Pesticides of Washington, D.C. “Chemical lawn pesticides are scientifically linked to cancer in people and pets, and are known to be toxic to the nervous and immune system, endocrine disruptors, and tied to respiratory effects such as asthma. Alternative practices that rely on maintenance techniques and soil health that prevent unwanted insect and weeds are far more effective than their chemical counterparts.” Now, for 80 percent of Canadians and a growing number of Americans, synthetic chemical lawn pesticides are becoming a habit of the past. In 1991, exactly six years from the first day she voiced her concerns at a town meeting, May 6, […]

(Beyond Pesticides, April 1, 2011) A British government scientist on Wednesday announced that he has ordered a review of a class of pesticides known as neonicotinoids, to determine what effects they may have on bee and pollinator health. Neonicotinoids, such as clothianidin and imidacloprid, have come under intense scrutiny recently due to concerns regarding their toxicity to honeybees, which are essential for a secure food supply in their role as crop pollinators. This has led some to suggest that chemicals such as these could be contributors to honeybee Colony Collapse Disorder (CCD). According to the London Daily Mail, the chief scientist at the UK Department of Environment, Food and Rural Affairs (DEFRA), Professor Robert Watson, has directed DEFRA scientists to reexamine findings on neonicotinoids and their effects on bees. The Mail suggests that Watson may have been partly motivated by a recent study done by Dr. Jeffrey Pettis of the U.S. Department of Agriculture’s Agricultural Research Service. This study was the first to show that neonicotinoids impact the survival of bees at levels below the level of detection, meaning that field studies would not have considered the role of the pesticide, because they would not have detected it. Although a […]

(Beyond Pesticides, March 14, 2011) Scientists working for the United Nations (UN) reveal in a report published March 10, 2011 that the collapse of honeybee colonies is now a global phenomenon that could have devastating consequences. Declines in managed bee colonies, seen increasingly in Europe and the US in the past decade, are now being observed in China, Japan and Egypt according to the report, “Global Bee Colony Disorders and other Threats to Insect Pollinators,” from the United Nations Environment Programme (UNEP). In the UNEP report, leading honeybee experts in the world stress that the potentially disastrous decline in bees —which are a vital pollinating element in food production for the growing global population””is likely to continue unless humans profoundly change their ways from the use of insecticides to air pollution. “The way humanity manages or mismanages its nature-based assets, including pollinators, will in part define our collective future in the 21st century,” UNEP Executive Director Achim Steiner said. “The fact is that of the 100 crop species that provide 90 per cent of the world’s food, over 70 are pollinated by bees.” “Human beings have fabricated the illusion that in the 21st century they have the technological prowess to […]

(Beyond Pesticides, February 23, 2011) In response to a request by beekeepers and environmentalists to remove a pesticide linked to Colony Collapse Disorder (CCD), the U.S. Environmental Protection Agency (EPA) in a letter, defended the pesticide clothianidin and the scientific study in question which was identified by beekeepers as a critically flawed study. EPA states that it does not intend to suspend or cancel clothianidin, even though independent studies have linked this chemical and others in its class to bee decline. Beyond Pesticides, as a part of a group of environmentalists and beekeepers, broke the news last December that a core study underpinning the registration of the insecticide clothianidin was unsound, citing leaked EPA memos which discloses the critically flawed scientific study and its reclassification as a “core” study on which clothianidin’s conditional registration was contingent on, to a “supplemental” study. Bayer CropSceicne, manufacturer of clothianidin designed and submitted to study to EPA as part of clothianidin’s registration requirement. Beekeepers claim that the initial field study guidelines, which the Bayer study failed to satisfy, were insufficiently rigorous to test whether or not clothianidin contributes to CCD in a real-world scenario: the field test evaluated the wrong crop, over an insufficient […]

(Beyond Pesticides, January 25, 2011) Research by the U.S. Department of Agriculture’s (USDA) Bee Research Laboratory and Penn State University shows that the neonicotinoid insecticide imidacloprid contribute —at extremely low levels— to bee deaths and possibly colony collapse disorder (CCD), the widespread disappearance of honey bees that has killed off more than a third of commercial honey bees in the U.S. While the study has not been published yet, the UK’s The Independent newspaper reports that honeybees exposed to imidacloprid are more susceptible to the fungal pathogen Nosema. This is the first study to show that neonicotinoids impact the survival of bees at levels below the level of detection, meaning that field studies would not have considered the role of the pesticide, because they would not have detected it. USDA researcher Jeffrey Pettis, PhD and Penn State University researcher Dennis Van Engelsdorp, PhD explained their research in the 2010 documentary, The Strange Disappearance of the Honeybees (transcript courtesy of Grist.org): [Pettis] I’ve done a recent study actually in collaboration with Dennis van Engelsdorp and some other researchers, where we exposed whole colonies to very low levels of neo-nicotinoids in this case, and then ”˜challenged’ bees from those colonies, with Nosema […]

(Beyond Pesticides, December 9, 2010) Beekeepers and environmentalists called on the U.S. Environmental Protection Agency (EPA) December 8, to remove a pesticide linked to Colony Collapse Disorder (CCD), citing a leaked EPA memo that discloses a critically flawed scientific support study. The November 2nd memo identifies a core study underpinning the registration of the insecticide clothianidin as unsound after EPA quietly re-evaluated the pesticide just as it was getting ready to allow a further expansion of its use. Clothianidin (product name “Poncho”) has been widely used as a seed treatment on many of the country’s major crops for eight growing seasons under a “conditional registration” granted while EPA waited for Bayer Crop Science, the pesticide’s maker, to conduct a field study assessing the insecticide’s threat to bee colony health. Bayer’s field study was the contingency on which clothianidin’s conditional registration was granted in 2003. As such, the groups are calling for an immediate stop-use order on the pesticide while the science is redone, and redesigned in partnership with practicing beekeepers. They claim that the initial field study guidelines, which the Bayer study failed to satisfy, were insufficiently rigorous to test whether or not clothianidin contributes to CCD in a real-world […]

(Beyond Pesticides, November 22, 2010) The British Beekeepers’ Association (BBKA) last week announced plans to end its controversial practice of endorsing pesticides for financial benefit from leading chemical manufacturers. The endorsement of four products as “bee-friendly” caused outrage among many beekeepers because one of the companies, Bayer Crop Science, makes pesticides like imidacloprid, an insecticide widely implicated in the deaths of honeybees worldwide. The 135-year-old charity endorsed pesticides used to combat the varroa mite that is linked to the collapse of colonies as “bee-friendly.” In return, for the past 12 years the association has received ÂŁ17,500 ($27,949) a year from Bayer Crop Sciences and Syngenta. This relationship angered many members and some left the association. However, the BBKA denies that it has bowed to pressure from members who have been increasingly critical of its relationship with Bayer and other chemical companies. In a statement sent out this week to the secretaries of local beekeeping associations across the UK, the BBKA’s president, Martin Smith, said: “Following discussion with the companies involved, the BBKA trustees have decided that endorsement and related product-specific payments will cease as soon as practically possible.” He added: “The four products subject to BBKA endorsement are of declining […]

(Beyond Pesticides, October 8, 2010) Scientists may have found the missing link behind the colony collapse disorder (CCD): a combination of a virus and a fungus, though more research is needed to determine the exact cause and effect that these two culprits have on CCD. Prior to this study, scientists have hypothesized that there are numerous factors, including pesticides, that depress the immune and nervous system of bees, creating a vulnerability to other factors, such as those identified in this study. Army scientists in Maryland and entomologists in Montana teamed up to find that the co-occcurrence of the viruses, the invertebrate iridescent virus (IIV) with the fungus Nosema ceranae (which was previously implicated as a culprit) consistently marked a colony collapse. The study, Iridovirus and Microsporidian Linked to Honey Bee Colony Decline was published October 6th in the online science journal PLoS One. Researchers looked at the proteins of thousands of healthy and collapsing bee colonies using mass spectrometry-based proteomics (MSP) that revealed two previously unreported RNA viruses in honey bees in North America, one of which is the IIV. Researchers say this virus is similar to a virus that was first reported in India 20 years ago, as well […]

(Beyond Pesticides, September 30, 2010) A new study finds a clear link between a decline in wild pollinators and reduced vegetable yields in India, which researchers say will harm both the nation’s GDP as well as access to a nutritional diet. Parthiba Basu, PhD, one of the researchers from the University of Calcutta’s Ecology Research Unit, says that nutritional security in India will be affected as a result of the decline, since the vegetables that rely on pollination substantially provide essential nutrients to the population. The research team, which presented its findings at a recent British Society meeting at the University of Leeds, compared the yields of pollinator-dependent crops such as pumpkins, squash and cucumbers with pollinator-independent crops, such as cereals. The data shows that while yields of pollinator-independent crops continue to increase, the crops that are dependent on pollinators have leveled off. Though the researchers would have liked to specifically compare pollinator abundance over the years, this kind of data is not currently available in India. The use of domesticated bees for pollinating crops is not widespread in India and across South Asia, according to Dr. Basu. He attributes the “political noise” in the U.S. and Europe on the […]

(Beyond Pesticides, August 26, 2010) Researchers from Indiana University have detected organochlorine pesticides and flame retardants in blood samples taken from bald eagle nestlings in the Great Lakes region. After DDT was banned, many scientists expected the bald eagle population to recover more quickly, so this study provides some evidence to explain their lackluster rebound. The researchers found not only organochlorines and PCBs (polychlorinated biphenyls), but several flame retardants commonly used in foam padding, such as pentabromoethylbenzene (PBEB), hexabromocyclododecanes (HBCDs) and Dechlorane Plus (DP). The paper, published in the August issue of the scientific journal Chemosphere was authored by Marta Venier of Indiana University. Ms. Venier and her colleagues collected blood samples by climbing trees to access the nests, carrying the nestlings carefully to the ground, and drawing a small blood sample before returning them to their nests. The statistically significant relationship between the total PBDE concentrations and total PCB concentrations suggest that these young eagles are ingesting pesticides and flame retardants through their food. Even low levels of these chemicals could be advsersely affecting the eagle population because as co-author of the study, Ronald Hites of Indiana University says, “Eagles are very vulnerable to chlorinated compounds.” Chlorinated materials are […]

(Beyond Pesticides, August 4, 2010) Several coastal towns in Maine, concerned about water contamination and the potential for the effects on aquatic life, have adopted restrictions on lawn chemicals. Pesticide opponents praise towns for cutting back on pesticide use but say that a ban on private use would make a bigger difference. Ogunquit is among the growing number of Maine towns that are restricting the use of lawn chemicals from municipal property because of environmental and public health concerns. About two dozen other communities have adopted some form of pesticide limits, including Brunswick, Castine and Harpswell. There are common traits among the towns that are limiting pesticides. They tend to have affluent residents that do more lawn care applications employing lawn care companies. Mike Horn, chair of Ogunquit’s Conservation Commission, helped to guide the pesticide restriction to passage at last year’s town meeting. Mr. Horn is worried about lawn chemicals such as phoshorous and nitrogen running downhill during rain. “What is going to happen if this level of pesticides just continues to rise and people’s lawns are just running, you’re just putting a big nail in Mother’s nature’s foot,” said Mr. Horn. He added that by protecting the environment, the […]

(Beyond Pesticides, August 3, 2010) A new study shows that due to a flaw in standard risk assessments, which consider toxic effects at fixed exposure times, the risks posed by the neonicotinoid pesticides imidacloprid and thiacloprid are likely to be underestimated. The authors believe that minute quantities of imidicloprid may be playing a much larger role in killing bees over extended periods of time than previously thought. The study, “The significance of the Druckrey—KĂĽpfmĂĽller equation for risk assessment””The toxicity of neonicotinoid insecticides to arthropods is reinforced by exposure time,” was published online July 23, 2010 in the journal Toxicology. The authors believe that standard risk assessment calculations underestimate toxicity because they do not accurately account for the interplay of time and level of exposure. According the study: The essence of the Druckrey—KĂĽpfmĂĽller equation states that the total dose required to produce the same effect decreases with decreasing exposure levels, even though the exposure times required to produce the same effect increase with decreasing exposure levels. Druckrey and KĂĽpfmĂĽller inferred that if both receptor binding and the effect are irreversible, exposure time would reinforce the effect. The Druckrey—KĂĽpfmĂĽller equation explains why toxicity may occur after prolonged exposure to very low toxicant […]

(Beyond Pesticides, March 30, 2010) Searching for clues to the mysterious disappearance of bees, known as “colony collapse disorder”(CCD), Penn State University researchers have identified widespread pesticide contamination of beehives. The study, “High Levels of Miticides and Agrochemicals in North American Apiaries: Implications for Honey Bee Health,” was published March 19, 2010 in the scientific journal Public Library of Science (PLOS). The study finds 121 different types of pesticides within 887 wax, pollen, bee and hive samples from 23 states. The top 10 most frequently detected pesticides are fluvalinate, coumaphos, chlorpyrifos, chlorothalonil, amitraz, pendamethalin, endosulfan, fenpropathrin, esfenvalerate and atrazine. Miticides are the most common contaminant in the wax and bees, and fungicides are the most common contaminant of pollen. For the full results of the study, including several tables of wax, pollen and bee sample data, download the study from the PLOS website. “The pollen is not in good shape,” Chris Mullin, PhD, lead author of the study, told Discovery News. The authors state that the 98 pesticides and metabolites detected in mixtures up to 214 parts per million (ppm) in bee pollen alone represents a remarkably high level for toxicants in the brood and adult food of this primary […]

(Beyond Pesticides, March 10, 2010) A study investigating the sublethal effects of pyrethroids, bifenthrin and deltamethrin on honeybees finds that the chemicals significantly impair the pollinators’ reproduction. The researchers also point out that the concentration of each pesticide that produced adverse effects in the experiments was at or below those that bees could encounter while pollinating treated crop fields. “Effects of sublethal concentrations of bifenthrin and deltamethrin on fecundity, growth, and development of the honeybee Apis mellifera ligustica” published in the March issue of Environmental Toxicology & Chemistry, investigated the effects of the two pesticides at sublethal concentrations on fecundity, growth, and development of honeybees were examined with the feeding method for a three-year period (2006-2008). It was shown that both bifenthrin and deltamethrin significantly reduced bee fecundity, decreased the rate at which bees develop to adulthood, and increased their immature periods. Queens in the control group in 2006 laid a little more than 1,200 eggs each day, compared to not quite 900 a day in the bifenthrin group and roughly 600 per day in the deltamethrin group. In general, the hatch rate of pyrethroid-exposed eggs was also significantly depressed. The success rate of hatchlings, that is the share that […]

(Beyond Pesticides, February 3, 2010) Beyond Pesticides has confirmed exciting additions to Greening the Community, the 28th National Pesticide Forum, scheduled for April 9-10 at Case Western Reserve University in Cleveland, OH. The Forum is an important opportunity to discuss the latest information on pesticides and alternatives, meet scientists and community leaders, and network with other activists working to change policies at the local, state and national levels. David Hackenberg, the beekeeper who first discovered a mysterious disappearance of honeybees now known as colony collapse disorder (CCD), is the most recent addition to the program. Mr. Hackenberg believes that pesticides contribute to CCD and that honeybees are a barometer of the environment. Featured in several films and news investigations, he has been front and center in this important fight to protect our pollinators. Read about Mr. Hackenberg and the other Forum speakers in the highlights below. The Forum will begin Friday afternoon with a tour of the Cleveland Botanical Garden. Founded in 1930, Cleveland Botanical Garden, which is now made up of 20 specialty gardens and exotic indoor biomes, has evolved into a community treasure. The Garden’s community involvement extends beyond its 10 acres into city neighborhoods through its Green […]
