(Beyond Pesticides, October 15, 2015) A new study, published in Environmental Science & Technology, has found that wildflowers bordering fields that are treated with neonicotinoids contain a higher concentration of the bee-toxic pesticides than the actual treated fields, pointing out an often overlooked avenue of exposure for bees. Widely-used neonicotinoids, which as systemic chemicals move through a plant’s vascular system and express poison through pollen, nectar, and guttation droplets, have been identified in multiple  peer-reviewed studies  and by beekeepers  as the major contributing factor in bee decline. The study, titled Neonicotinoid Residues in Wildflowers, A Potential Route of Chronic Exposure for Bees, discovered neonicotinoid insecticides in wildflowers, including Hogweed and Poppy pollen (up to 86ppb and 64ppb, respectively). The study’s authors  found higher concentrations of neonicotinoids in wild flowers in field margins than in Oilseed rape flowers in the adjacent neonicotinoid treated crop — on average 15ppb vs. 3ppb.   They also found that more than 97% of the neonicotinoids being brought into the hive by honey bees are from wildflowers, while only 3% are  from the crop. Researchers have found  that chronic exposure to neonicotinoids increases neuronal vulnerability to mitochondrial dysfunction in the bumblebee. In other words, these pesticides […]

(Beyond Pesticides, September 18, 2015) Glyphosate’s harmful effects continue to accumulate, this time with evidence pointing to toxic and sublethal effects on bees. According to a new study conducted by German and Argentinian researchers, honey bees exposed to low levels of glyphosate have a hard time returning home. Glyphosate, the  controversial and toxic active ingredient in Monsanto’s Roundup, is an herbicide widely used on genetically-engineered (GE) crops as well as on parks and golf courses, for control of weeds and grasses. Along with neonicotinoids, which have been linked to worldwide bee decline by a growing body of science, glyphosate is just another chemical in the toxic mixture that bees and other non-target organisms are constantly exposed to in the environment. In the study, titled “Effects of sublethal doses of glyphosate on honeybee navigation” and published in the Journal of Experimental Biology, researchers evaluate the effects of recommended concentrations of glyphosate used in agricultural settings on honey bee navigation and found that a single exposure to a concentration of glyphosate within this range delays the return of the foraging honey bee to the hive. Flight trajectories were also affected after successive exposure to the herbicide, suggesting that the spatial learning process […]

(Beyond Pesticides, September 10, 2015) Last week, California Environmental Protection Agency’s Office of Environmental Health Hazard Assessment (OEHHA) announced that it intended to list glyphosate (Roundup) and three other chemicals as cancer-causing chemicals under California’s  Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65). Glyphosate  is a phosphanoglycine herbicide that inhibits an enzyme essential to plant growth. Under California law, Proposition 65 requires that certain substances identified by the International View postAgency for Research on Cancer (IARC) be listed as known cancer-causing chemicals. In March, a study by the IARC classified glyphosate as a Group 2A material, which means that the chemical is carcinogenic based on sufficient evidence of carcinogenicity in experimental animals. The agency considered the findings from an EPA Scientific Advisory Panel report, along with several recent studies in making its conclusion. However, industry supporters of glyphosate all over the globe are conducting their own studies to attempt to prove that it is not a carcinogen. These studies, like one by German Federal Institute for Risk Assessments (BfR), are based almost solely on industry science and classified industry reports, each of which might not consider critical variables. With more glyphosate-focused studies being released, the growing evidence […]

(Beyond Pesticides, September 1, 2015) A  research study published in the journal Environmental Health  links chronic, ultra-low dose exposure to glyphosate in drinking water to adverse impacts on the health of liver and kidneys. The study, Transcriptome profile analysis reflects rat liver and kidney damage following chronic ultra-low dose Roundup exposure, is the latest in a string of data showing unacceptable risks resulting from exposure to glyphosate and products formulated with the chemical, like Monsanto’s Roundup. Researchers conducted the study by exposing rats to minute (0.1 parts per billion) doses of Roundup in drinking water for a period of 2 years. After noting tissue damage and biochemical changes in the blood and urine of exposed animals that was indicative of organ damage, the authors attempted to confirm their findings by analyzing changes in gene expression within liver and kidneys. Of 4,447 gene transcript clusters analyzed by scientists, 4,224 showed some alteration. Compared to non-exposed rats, “[t]here were more than 4,000 genes in the liver and kidneys whose levels of expression had changed,” said Michael Antoniou, PhD, senior author of the study to Environmental Health News. Authors indicate that the changes in gene expression observed in the study are associated with […]

(Beyond Pesticides, July 30, 2015) Despite concerns for human and environmental contamination, the U.S. Department of Agriculture (USDA) adds 2,4-D-tolerant cotton, a genetically engineered (GE) crop, to the list of unregulated GE crops, joining 2,4-D resistant corn and soybeans. Last week, the Animal and Plant Health Inspection Service (APHIS) division of USDA released its decision on Dow AgroSciences’ petition to deregulate the 2,4-D resistant GE cotton. The decision was signed off by Michael J. Firko, the Deputy Administrator of Biotechnology Regulatory Services. In September of last year, Deputy Firko also signed the determination paperwork that deregulated GE corn and soybean. The deregulation essentially releases the GE organism from the regulatory requirements of 7 CFR part 340 or the plant pest provisions of the Plant Protection Act. Dow’s GE cotton, part of the Enlist Weed Control System, is resistant to 2,4-D choline, glufosinate, and glyphosate. Growers in the cotton industry have been vying for the GE cotton to enter the market in order to combat herbicide-resistant weeds due to the broad scale use of Monsanto’s RoundUp (glyphosate), which continues to fail across the agricultural industry due to weed resistance. Glyphosate is a phosphanoglycine herbicide that inhibits an enzyme essential to plant […]

(Beyond Pesticides, June 30, 2015) As the Monarch butterfly suffers serious decline, the U.S. Environmental Protection Agency (EPA) is considering  the role of  herbicides in killing the iconic species’ food source, milkweed, and developing an action plan that may fall short. The agency identified possible action that it may take to slow the Monarchs’ decline in a document released last week entitled Risk Management Approach to Identifying Options for Protecting the Monarch Butterfly (Monarch Approach document). EPA’s approach to Monarch conservation comes shortly after the White House released its National Pollinator Health Strategy, intended to “reverse pollinator losses and help restore populations to healthy levels.” The U.S. Fish and Wildlife Service is also in the midst of conducting a review of the Monarch butterfly to determine whether the species is eligible for protection under the Endangered Species Act. The number of Monarchs reaching their winter breeding grounds in Mexico has fallen by 90% in less than 20 years. This year’s population was the second lowest since surveys began two decades ago. The critical driver of this decline has been linked to the loss of milkweed, the only plant on which Monarchs will lay their eggs, along their migration route, which […]

(Beyond Pesticides March 18, 2015) Fifty-two members of Congress penned a letter to the White House, calling for the protection of the Monarch butterfly, which has declined by 90 percent in the last 20 years, and for listing as a ”˜threatened’ species under the Endangered Species Act (ESA). This comes on the heels of a formal  notice  of intent to sue submitted to the U.S. Environmental Protection Agency (EPA) for failing to protect threatened and endangered species, including butterflies, amphibians and birds, from flupyradifurone, a newly approved systemic insecticide. The letter sent to President Obama on Tuesday was spearheaded by Representative Chellie Pingree (D-ME), a long-time advocate for protecting monarch butterflies. In her press release, Rep. Pingree notes that the annual migration of monarchs from North America to Mexico has plummeted because of the use of herbicides on genetically engineered (GE) crops in the U.S.   The herbicides have wiped out milkweed, the main food for monarchs.  According to the letter, efforts by farmers, local, state and federal agencies to boost habitat are laudable, but without changes in how the federal government addresses the use of herbicides, especially as applied to herbicide-resistant crops, vital monarch habitats will simply continue to […]

(Beyond Pesticides, February 27, 2015) New research from the University of Minnesota presents some of the first evidence linking the bee-killing insecticides known as neonicotinoids to monarch butterfly deaths. The study finds that milkweed plants, which monarch butterflies need to survive, may also retain neonicotinoids from nearby plants, making milkweed toxic to monarchs. Monarch population numbers have fallen by 90% in less than 20 years. This year’s population was the second lowest since careful surveys began two decades ago. The critical driver of monarch decline  is the loss of larval host plants in their main breeding habitat, the midwestern Corn Belt. Monarchs lay eggs exclusively on plants in the milkweed family, the only food their larvae will eat. University of Minnesota entomologist Vera Krischik, Ph.D. fed butterflies milkweed plants treated with the neonicotinoid insecticide known as imidacloprid in amounts that might typically be found on backyard plants. While adult monarchs and painted lady butterflies were not affected, which, according to Dr. Krischik, indicates the ability of the adults to detoxify, the larvae of both species of butterflies died. During the course of the study, larvae fed on the treated plants for seven days. “For the monarch, nobody was left that […]

(February 9, 2015, Beyond Pesticides) A report, Monarchs in Peril: Herbicide-Resistant Crops and the Decline of Monarch Butterflies in North America, released by Center for Food Safety (CFS) last week, reveals the devastating  impact of Monsanto’s and the nation’s biggest selling herbicide, Roundup (glyphosate), on the survival  of monarch butterflies. The herbicide is  used to treat  millions of acres of herbicide-tolerant  genetically engineered (GE) crops, eliminating the monarchs’ sole source  of food, milkweed, and approaching  a collapse of their population, which has plummeted over the past 20  years. The report cites findings that  glyphosate use on Roundup Ready  (glyphosate-tolerant) crops has nearly eradicated milkweed around farmland in the monarchs’ vital midwest breeding ground. At the urging of scientists and public interest groups, the U.S. Fish and Wildlife Service (FWS) is currently considering listing the monarch as a threatened species under the Endangered Species Act (ESA). “This report is a wake-up call. This iconic species is on the verge of extinction because of Monsanto’s Roundup Ready crop system,” said Andrew Kimbrell, executive director at Center for Food Safety. “To let the monarch butterfly die out in order to allow Monsanto to sell its signature herbicide for a few more years is […]

(Beyond Pesticides, January 6, 2015) At the close of 2014, the U.S. Fish and Wildlife Service (FWS) announced plans to conduct a year-long status review of the monarch butterfly to determine whether the species is eligible for protection under the Endangered Species Act (ESA). FWS is taking this action as result of an August 2014 legal petition filed by health and environmental groups that presented substantial information indicating that listing under the ESA may be warranted. In November 2014, Beyond Pesticides joined over 200 environmental groups and businesses in a letter asking for federal protection for monarch butterflies in the wake of shocking declines. The North American monarch butterfly population fell by 90 percent in the past 20 years, dropping from a high of approximately  one billion in the mid-1990s to fewer than 35 million butterflies in the winter of 2013-2014— the lowest number ever recorded. Each year monarch butterflies travel over 2,000 miles between Canada, the U.S., and Mexico, across multiple generations, to reach their winter hibernation grounds in late October. As FWS indicates, this journey has become “more perilous for many monarchs” due to threats along their migratory paths. Scientists believe the butterfly’s decline is being driven in […]

(Beyond Pesticides, November 14, 2014) In the face of staggering declines of monarch butterflies, more than 40 leading scientists and 200 organizations and businesses this week urged the Secretary of the Department of the Interior, Sally Jewell, to protect these butterflies under the Endangered Species Act (ESA). These groups and scientists are supporting the formal petition to the U.S. Fish and Wildlife Service (FWS) submitted this summer, which seeks federal protection for monarch butterflies. Forty scientists from around the U.S. and Mexico signed on to a letter requesting protected status for the butterflies and for FWS to recognize the importance of continued research by scientists and citizen scientists in understanding and conserving the monarch butterfly and its habitat. The scientists also request FWS to streamline the permitting process, so that scientific and conservation research and citizen science activities are encouraged rather than deterred by a listing. In a separate letter, over 200 environmental groups and businesses called on FWS to take swift and effective action by granting the monarch butterfly protection as a threatened species under the ESA. Both letters come in support of a formal petition to FWS seeking federal protection for monarchs. The petition was filed in August […]

(Beyond Pesticides, October 31, 2014) Without any mention of the role of pesticides in bee decline, or emphasis on organic practices to help pollinators, Agriculture Secretary Tom Vilsack announced Wednesday that more than $4 million in technical and financial assistance will be provided to help farmers and ranchers in the Midwest improve the health of honey bees. The announcement renews and expands on a $3 million pilot investment last spring to create pollinator-friendly habitat in five Midwestern states. The effort responds to the Presidential Memorandum, which directs USDA to expand the acreage and forage value in its conservation programs. The Memorandum, issued at the close of National Pollinator Week 2014, directed federal agencies to establish a Pollinator Health Task Force, and tasked agency leads at the U.S. Department of Agriculture (USDA) and U.S. Environmental Protection Agency (EPA) to develop a pollinator health strategy within 180 days that supports and fosters pollinator habitat. “The future of America’s food supply depends on honey bees, and this effort is one way USDA is helping improve the health of honey bee populations,” Vilsack said. “Significant progress has been made in understanding the factors that are associated with Colony Collapse Disorder and the overall health […]

(Beyond Pesticides, August 29, 2014) Environmentalists issued a legal petition to the U.S. Fish and Wildlife Service on Tuesday calling for the protection of the monarch butterfly as a threatened species under the  Endangered Species Act (ESA). Monarch butterflies, a striking and familiar symbol of beauty and nature in the U.S., have had their population decline by a staggering 90 percent in the past two decades alone, most likely due to a significant loss of habitat of more than 165 million acres – an area about the size of Texas -as well as nearly a third of their summer breeding grounds. Part of the decline of monarch butterflies  stems from the loss of milkweed, a native plant where the butterflies lay their eggs and is their main food source. Although little use to farmers, milkweed is an important plant to butterflies, wasps, and bees. A recent study attributed the disappearance of milkweed plants primarily to the use of genetically-engineered (GE) corn and soybean crops. The widespread adoption of GE agriculture and the ever-growing use of herbicides are contributing extensively to the loss of milkweed areas. Scientists also point to the prolific use of herbicides in the Midwest eliminating these plants, […]

(Beyond Pesticides, January 21, 2013) Two Minnesota state agencies are creating plans they say will  address declining pollinator populations in the state. The Minnesota Department of Natural Resources (DNR) is developing best management practices for managing and increasing pollinator habitat and the Minnesota Department of Agriculture (MDA) is developing a plan to study the impacts of neonicotinoid pesticides on pollinators. Critics of the state’s plan say that there is no more need to study the effects of neonicotinoids because the negative impacts they have on pollinators has been already studied extensively.   The DNR is developing guidelines to improve habitat for pollinator insects. Recent reports show that  the planting of herbicide-resistant genetically engineered (GE) crops is responsible for habitat loss and the decline of native pollinators like the Monarch butterfly. The expansion of glyphosate tolerant GE corn and soybean cropland has allowed farmers to kill milkweed, the primary source of food for Monarchs, which historically grew between crop rows in the Midwest. A rapid expansion of farmland ””more than 25 million new acres in the U.S. since 2007”” has also eaten away grasslands and conservation reserves that supplied the Monarchs with milkweed. DNR officials have indicated this guide could change […]

(Beyond Pesticides, December 9, 2013) Unless regulators take action,  one of the gifts in the lyrics to “Twelve Days of Christmas,” the turtle dove,  may  become extinct. The dove has experienced major population decline in England over the past 20 years, due in significant part to the destruction of  turtle dove habitat and food sources from  increasing herbicide use in English agriculture. Other species, such as Monarch butterflies and other pollinators around the world, are also experiencing similar loses of habitat and food sources through an increase in herbicide use. These increasing rates of population decline in wild species underscore the problem that chemical-intensive agriculture plays in the degradation of natural habitats. According to a spokesman for the Royal Society for the Protection of Birds, “The turtle dove is the fastest declining bird in the country [England] and within ten years we could lose this icon of the British countryside completely.” Turtle doves in the United Kingdom are found in just a few areas of Southern England and migrate during the winter toward Africa. Turtle doves are obligate granivors, feeding predominantly on seeds of certain arable weeds form farm countryside, such as fumitory, clover and vetch. However, increased herbicide use […]

(Beyond Pesticides, March 20, 2013) Loss of habitat to genetically engineered (GE) cropland, as well as increasingly warm temperatures are responsible for the dramatic decline in Monarch butterfly populations, according to scientists who say populations are the lowest they have seen in two decades.  This comes as the state of pollinators continues to reach crisis levels, with honey bee colonies also experiencing alarming declines. Scientists who take the annual measure of Mexican forestland famously occupied by migrating monarch butterflies find that forestland occupied by the butterflies, once as high at 50 acres, dwindled to 2.94 acres. This is a 59 percent decline from the 7.14 acres of butterflies measured in December 2011. The survey carried out in December and January, reported nine monarch colonies wintering in central Mexico, occupying a total of 1.19 hectares, or 2.94 acres. The results were released by the World Wildlife Fund-Mexico, and Mexico’s National Commission of Natural Protected Areas (CONANP). This population is the smallest recorded since the Monarch colonies came to the attention of scientists in 1975. To explain this drastic decline, researchers point to the loss of Monarch habitat in the U.S. and Mexico to increasing cropland and the widespread use of the […]
