(Beyond Pesticides, June 21, 2017) More than 200 international scientists and medical professionals have signed the Florence Statement on Triclosan and Triclocarban, which states that triclosan and its chemical cousin triclocarban pose a risk to human health, and urges the international community to limit use of these antimicrobials, which are associated with bacterial resistance and no more effective than soap and water. In 2016 after manufacturers failed to prove efficacy, the U.S. Food and Drug Administration (FDA), which regulates cosmetic triclosan products, announced that manufacturers must, by September 2017, remove triclosan from over the counter hand soaps. The agency still allows the chemical in toothpastes and other products, such as hand wipes. The Environmental Protection Agency (EPA), which regulates triclosan in household items, textiles and plastics, still permits wide use of the chemical in a range of products. The Florence Statement on Triclosan and Triclocarban is âbased on extensive peer-reviewed research,â and âconcludes that triclosan and triclocarban are environmentally persistent endocrine disruptors that bioaccumulate in and are toxic to aquatic and other organisms.â The statement includes evidence of human health threats, and provides recommendations intended to mitigate harm from triclosan, triclocarban, and other similar antimicrobials. The recommendations are listed below: âAvoid […]

(Beyond Pesticides, June 13, 2017) Prenatal exposure to commonly used mosquito and agricultural insecticides is associated with decreased motor function in infants, according to a study published in Environment International by a team of Chinese and U.S. researchers. The results of the study should give pause to insecticide-heavy efforts to control mosquitoes as the season ramps up this summer and fall. Frequent spraying as part of efforts to control Zika in Southern Florida last year resulted in large protests and calls for a preventive management approach not dependent on toxic chemicals. For the current study, over 350 pregnant Chinese mothers were tested for the presence of organophosphate pesticides in their umbilical cord blood. Researchers looked at exposure to the insecticides naled, methamidophos, trichlorfon, chlorpyrifos, and phorate. After giving birth, their childrenâs motor function was tested at both six and nine months of age. Tests included an analysis of the infantâs reflexes, locomotion, grasping, stationary and visual-motor integration abilities. Scores were categorized based on gross, fine, and total motor skills, and standardized quotients were created for each of the categories. Of the over 300 mothers, roughly 240 had detectable levels of one of the insecticides in their samples. Although no differences […]

(Beyond Pesticides, June 6, 2017) Last week, the U .S. Court of Appeals for the Ninth Circuit concluded that the U.S. Environmental Protection Agency (EPA) failed to show that its conditional registration of the antimicrobial, nano-silver pesticide product âNSPW-L30SSâ (previously âNanosilvaâ) is in the public interest and revoked its registration. The case, brought by the Natural Resources Defense Council (NRDC) and the Center for Food Safety (CFS), challenged the approval of the novel nanotechnology which was marketed for use in an unknown number of textiles and plastics. The decision underscores the need for EPA to ensure pesticide products, including nanomaterials, meet the standards of federal pesticide law. According to the Center for Food Safety, the Courtâs decision is the first of its kind to address EPAâs responsibilities in issuing conditional registrations of new pesticide products like NSPW-L30SS. In its ruling, the Court ruled that EPA had failed to show that âconditional approvalâ of NSPW-L30SS as a new pesticide supported a public interest finding by the EPA with substantial evidence. EPA had conditionally registered the controversial pesticide back in 2015. Under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), EPA can only conditionally register new active ingredients, such nanosilver particles, if EPA […]

(Beyond Pesticides, May 26, 2017) On Wednesday, the U.S. House of Representatives voted to pass a bill that would reverse an Environmental Protection Agency (EPA) requirement to obtain a permit before spraying pesticides on or near waterways. The passage of HR 953, The Reducing Regulatory Burdens Act (known by environmentalists as the âPoison Our Waters Actâ), is the latest update in a multi-year string of attempts to rollback commonsense protections for the public waterways all Americans use for swimming, fishing, and other forms of recreation. It will now move forward to be considered by the Republican-majority Senate, where it will most likely pass and be signed into law. HR 953, if signed into law, would reverse a 2009 decision issued by the 6th Circuit Court of Appeals, in the case of National Cotton Council et al. v. EPA, which held that pesticides applied to waterways should be considered pollutants under federal law and regulated under the Clean Water Act (CWA), through National Pollutant Discharge Elimination System (NPDES) permits. Prior to the decision, the EPA, under the Bush Administration, had allowed the weaker and more generalized standards under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) to be followed. This allowed pesticides to be discharged […]

(Beyond Pesticides, April 27, 2017) Multinational chemical companies Dow Chemical Company and Shell Chemical Company knowingly sold and marketed fumigants contaminated with a cancer-causing chemical that had a strong propensity to leach into and remain in groundwater, according to a recent report from the Environmental Working Group (EWG) and a lawsuit against the companies. The contaminant of concern, 1,2,3-trichloropropene (TCP), was a manufacturing by-product found in Dowâs Telone and Shellâs D-D fumigant pesticide products with the active ingredient 1,3-Dichloropropene. The products, used to kill soil-dwelling nematodes, are toxic in their own right, but contained TCP in their formulation from the 1940s until the mid-1980s. EWGâs report details widespread contamination of drinking water in Californiaâs agricultural regions, with detections found in 562 wells, and 94 public water systems identifying TCP above legal limits. Thirty-seven additional public water systems serving nearly 4 million U.S. residents throughout the country were also found to contain TCP. The U.S. Environmental Protection Agency has never set maximum contaminant levels for TCP in drinking water, but requires public reporting above the infinitesimally small amount of 30 parts per trillion, roughly six times higher than what the state of California requires. However, even proposed limits of 5 parts per trillion […]

(Beyond Pesticides, April 25, 2017) Past use of agricultural pesticides puts honey bees at risk across multiple growing seasons, according to research from scientists at Cornell University in New York. According to lead author Scott McArt, PhD, âOur data suggest pesticides are migrating through space and time.â Honey bees, which over the past decade have experienced unsustainable declines over 40% each year, are at great risk from exposure to a range of pesticides, chiefly the neonicotinoid class of insecticides. This new research adds to calls from beekeepers, environmental groups, and progressive farmers to transition agriculture away from pesticide-dependent practices. Cornell researchers conducted a massive study that analyzed both the pollen source and pesticide residue found therein for 120 experimental hives placed near 30 apple orchards in New York State. The landscapes surrounding each orchard were classified based on the amount of natural area or agricultural land that was present. Scientists analyzed risk to honey bees by collecting information about pesticide use during the growing season as well as the amount of pesticide contamination in âbeebread,â pollen tightly packed unto pellets by bees used as food or in the production of royal jelly. âBeekeepers are very concerned about pesticides, but thereâs […]

(Beyond Pesticides, April 13, 2017) With pesticide use rising in Southeast Asia, a new study is highlighting the importance of education and social dynamics in driving farmersâ decisions to spray. When women oversee agricultural pesticide use, according to the study, these farms use approximately 42% less pesticide than other farms. The research, published in Science of the Total Environment this month, aims to provide insight on methods that may be used to intervene and reduce pesticide dependence. The investigation comes at a critical time, as international bodies like the United Nations indicate that rampant pesticide use has the potential to negatively impact human rights, especially in developing countries. In Cambodia, Laos, and Vietnam, pesticide imports are growing at an annual rate of 61%, 55%, and 10%, respectively. These trends have international implications, as food imported from these countries is subsequently found contaminated with pesticides, with for example, 33% of crops imported to the European Union from Vietnam containing pesticide residue above maximum acceptable limits. To uncover the factors driving increased pesticide use in the region, researchers queried 900 vegetable farming households on their knowledge, attitude, and practices. Knowledge included understanding about best practices in agriculture, such as the difference between […]

(Beyond Pesticides, April 5, 2017) A new study, Occurrence of Neonicotinoid Insecticides in Finished Drinking Water and Fate during Drinking Water Treatment, has detected neonicotinoids, a class of insecticides known for their detrimental effects on bees, in treated drinking water. This marks the first time that these insecticides have been found in water sourced straight from the tap. Federal regulators have not yet addressed safe levels of neonicotinoids in drinking water, so at this point, any detection of these chemicals is cause for concern. The study authors âreport for the first time the presence of three neonicotinoids in finished drinking water and demonstrate their general persistence during conventional water treatment.â Drinking water samples “collected along the University of Iowa treatment train” over a seven week period, May through July, 2016 directly after corn and soy planting, find three neonicotinoids, clothianidin, imidacloprid, and thiamethoxam at levels ranging from 0.24 to 57.3 ng/L (nanogams per liter). The University of Iowa tap water is run through a water treatment plant that uses conventional treatment methods. In contrast, the Iowa City water treatment methods (granular activated carbon filtration) result in substantially lower levels of the neonicotinoids. Additionally, the researchers found that extensive transformation of clothianidin […]

(Beyond Pesticides, March 28, 2017) The U.S. Department of Agriculture (USDA) has abandoned its plans to test the U.S. food supply for the presence of glyphosate residues, according to a story from veteran reporter Carrey Gillam in The Huffington Post. The decision comes amid heated controversy over the carcinogenicity of glyphosate, which was cleared by a California judge for listing under Californiaâs Prop 65 earlier this year. The federal governmentâs pesticide monitoring program, which is run jointly by USDA, the Food and Drug Administration (FDA), and the Environmental Protection Agency (EPA), was criticized by the Government Accountability Office (GAO) in 2014 for its failure to test for the widely used herbicide. In early 2016, Beyond Pesticides met with EPA regulators to discuss testing for glyphosate residues in the U.S. food supply. At the time, officials said that FDA was testing honey, and USDA would be conducting more extensive food testing beginning in 2017. USDA had tested soybeans for glyphosate residue in 2011, finding that 90% of samples contained residues between .26 ppm and 18.5 ppm, barely under the allowed food tolerance level of 20ppm. A 2014 Boston University study had indicated that both organic and conventional honey contained glyphosate concentrations despite […]

(Beyond Pesticides, March 7, 2017) Another study, published by a team of French scientists in the journal Occupational and Environmental Medicine, links childhood behavioral problems to pyrethroid insecticide exposure. Synthetic pyrethroids are a class of insecticides that have increased in use over the past decade due to assumptions that they pose fewer risks to human health than older pesticide chemistries, such as organophosphates. However, this latest study is part of a growing body of research showing that pyrethroids share similar neurocognitive health concerns as these older pesticides. . In this research, scientists investigate the interplay between pyrethroid exposure and behavioral problems through a longitudinal cohort study, which tracks levels of pyrethroid metabolites, or breakdown products, in the urine of mothers beginning between six and 19 gestational weeks and then in their children up through six years of age. Childrenâs behavior is measured through a screening questionnaire known as the Strengths and Difficulties Questionnaire (SDQ). SDQ measures how social a child is (altruism), whether the child has difficulty sharing problems or asking for help (internalizing disorders), as well as how defiant or disruptive a child is (externalizing disorders). The study controlled for a number of confounding factors, such as weight, education, location (rural or […]

(Beyond Pesticides, February 21, 2016) The Agriculture Committee in the U.S. House of Representatives approved a bill last week that will eliminate protections from toxic pesticides for the nationâs waterways. The bill now moves on to the full House for a vote and the public has an opportunity to let Representatives hear the concerns about weakening local protection of waterways from toxic pesticides. HR 953, The Reducing Regulatory Burdens Act (code for the sponsors and supporters as legislation to eliminate environmental protection of water quality), is the committeeâs latest effort in a multi-year string of attempts to rollback common sense protections for the public waterways all Americans use for swimming, fishing, and other forms of recreation. The bill would repeal the Clean Water Act requirement that those who apply pesticides to waterways, with an exemption for farm use pesticides not directly deposited into waterways, obtain a National Pollutant Discharge Elimination System (NPDES) permit. Last May, at the height of fears over the Zika epidemic, the same Committee ushered through the same bill under another misleading name, The Zika Vector Control Act. Pensive lawmakers and the public saw through the ruse, and the bill was defeated. But, like previous iterations, including the 2015 Sensible Environmental […]

(Beyond Pesticides, February 13, 2017) A study by the World Wildlife Fund (WWF) and others  attributes the reduced number of overwintering monarch butterflies âa reduction of 27% from last yearâto herbicide use and other factors. The World Wildlife Fund (WWF), in conjunction with U.S. and Mexican environmental groups, has been leading the effort in tracking monarch butterflies. Their recently released 2016-2017 study concluded that the population of monarch butterflies decreased 27 percent from last yearâs population, which had marked an increase from dangerously low levels over the previous three years. Overall, this marks an 80 percent decline in monarch population from the 1990âs. Researchers have estimated that within 20 years the monarch butterfly migration could collapse altogether. The study was conducted in December of 2016 when the colonies of monarchs are expected to be at their peak population in Mexico. Monarch populations are gauged by the area of land they inhabit, rather than counts of butterflies.   Thirteen butterfly colonies were observed, recorded and tracked using geographic information systems software. The researchers found that the butterflies occupied 2.91 hectares of forest, which re presents a 27.43 percent decrease in population compared to the 4.01 hectares of forest they inhabited during the […]

(Beyond Pesticides, February 9, 2017) The failure of the U.S. pesticide regulatory system to protect marijuana users was highlighted as Health Canada announced Tuesday that it would begin conducting random pesticide residue testing of marijuana products to ensure that only registered products are being used in medical marijuana production. This comes on the heels of voluntary recalls in 2016 by two licensed Canadian cannabis producers due to the presence of the prohibited pesticides bifenazate, myclobutanil, and pyrethrins in or on marijuana products. Especially concerning is the detection of myclobutanil, a powerful fungicide that, when heated, converts to the hazardous gas hydrogen cyanide. The detection of these toxic chemicals in medical marijuana products is distressing since many users have compromised immune systems or health conditions that make them more susceptible to toxic chemicals. Moves by several states in the U.S. to curb illegal pesticide use in marijuana contain significant pitfalls and loopholes that allow contaminated cannabis to enter the market, where it threatens public health. Without examination of residues in inhaled, ingested, or absorbed cannabis, the userâs health is not protected by pesticide registration addressing other uses. In addition, environmental impacts associated with growing practices are generally ignored. On January 9th, […]

(Beyond Pesticides, February 7, 2017) After years of legal battle, the Colorado Court of Appeals last week affirmed a ruling that Colorado rancher, James Hopper, must serve two days in jail and pay a $7,500 fine for spraying pesticides that drifted unto his neighborâs farm in violation of a 2012 court order protecting his neighbors. In 2012, organic farmers Rosemary Bilchak and her husband Gordon MacAlpine, were granted a permanent injunction prohibiting pesticide applications within 150 feet of the property line in order to reduce pesticide drift. Last weekâs decision bolsters a legal precedent that wafting pesticides can constitute a trespass against which adjacent landowners and people with health sensitivities are protected. The legal battle began in 2011 when Mr. Hopper obtained his Colorado pesticide applicatorâs license and applied the adulticide Fyfanon, which contains the organophosphate insecticide malathion, to kill mosquitoes on his property. However, the pesticide drifted onto Ms. Bilchak and Mr. MacAlpineâs organic vegetable farm. In 2012, a District Court Judge ruled that they have a right not to have their property invaded by other people or things, and prohibited Mr. Hopper from fogging for mosquitoes within 150 feet of his neighborâs property or allowing the pesticides to drift, […]

(Beyond Pesticides, February 2, 2017) A commonly used inert pesticide ingredient negatively affects the health of honey bees by making larvae more susceptible to a virus, according to a recently published study in the journal, Nature. One of the authors of the study, Julia Fine, PhD candidate, stated that the findings, âMirror the symptoms observed in hives following almond pollination, when bees are exposed to organosilicone adjuvant residues in pollen, and viral pathogen prevalence is known to increase. In recent years, beekeepers have reported missing, dead and dying brood in their hives following almond pollination, and exposure to agrochemicals, like adjuvants, applied during bloom, has been suggested as a cause.â The study assessed honey bee larval development after exposure to a continuous low dose of Sylgard 309, a surfactant, in their diet. This organosilicone surfactant is commonly used on agricultural crops, including tree fruits, nuts, and grapes. Their results reveal that honey bee exposure to chemical surfactants such as Sylgard 309 led to higher levels of Black Queen Cell Virus and when the bee larvae were exposed to the surfactant and virus simultaneously, âthe effect on their mortality was synergistic rather than additive.â This research comes at a time when […]

(Beyond Pesticides, January 27, 2016) Last week, farmers, environmentalists, and conservation groups filed a federal lawsuit that challenges the U.S. Environmental Protection Agency’s (EPA) approval of a new formulation of the toxic herbicide dicamba. The new formulation is called Xtendimax with Vapor Grip Technology, which is claimed to have lower volatility. The petitioners claim that EPA violated its duties under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) in issuing a conditional registration, and that it did not adhere to duties under the Endangered Species Act that require EPA to consult with the U.S. Fish and Wildlife Service to ensure registration would not harm any listed species. The organizations involved in the lawsuit are National Family Farm Coalition, Pesticide Action Network North America, Center for Food Safety, and Center for Biological Diversity, represented by legal counsel from Earthjustice and Center for Food Safety. Dicamba has caused a lot of controversy in the past. In August 2016, farmers in Missouri, Arkansas, and Tennessee confronted widespread crop damage and braced for lower yields as a result of agrichemical giant Monsantoâs botched roll-out of GE soybean and cotton crops. The company, whose current line of glyphosate-tolerant crops are failing to control weeds throughout […]

(Beyond Pesticides, January 26, 2017) In a startling move that puts independent science at odds with government, the Trump administrationâs U.S. Environmental Protection Agency (EPA) transition team stated on Wednesday that scientists will now face âan unspecified vetting process before sharing their work outside the agency.â However, this kind of review is at odds with EPA’s own scientific integrity policy, which “prohibits all EPA employees, including scientists, managers, and other Agency leadership, from suppressing, altering, or otherwise impeding the timely release of scientific findings or conclusions.” This comes on the heels of an announcement by the administration several days ago issuing scientific grant and hiring freezes at EPA nationwide, along with effectively banning science communications through social media platforms. According to ProPublica, an EPA employee stated that, âHiring freezes happen, but freezes on grants and contracts seemed extraordinary.â These grants are used for financial support to complete environmental testing, remediation and environmental improvement projects across the country. Additionally, on Friday, January 20, after Donald Trump was officially sworn in, he ordered a freeze on all pending regulations from the Obama administration. This included the listing of the rusty patched bumblebee as endangered by the U.S. Fish and Wildlife Service, which had been set […]

(Beyond Pesticides, January 25, 2017) A study conducted at the University of Buffalo recently revealed a connection between two common insecticides and an increased risk for certain metabolic diseases, including diabetes. Researchers found that by binding to and disrupting melatonin receptors that control numerous physiological functions, chemicals such as insecticides can affect melatonin levels, creating a higher risk for metabolic diseases to develop. The study, Carbamate Insecticides Target Human Melatonin Receptors, was published in Chemical Research in Toxicology and was funded by a grant from the National Institute of Environmental Health Sciences, which is part of the National Institutes of Health. The implicated chemicals in this research, carbaryl and carbofuran, are notoriously dangerous carbamate insecticides. Carbamates share structural characteristics and an ability to inhibit acetylcholinesterase (AChE), an enzyme important for the transmission of nerve impulses. When AChE is inhibited, acetylcholine accumulates leading to overstimulation of neurotransmitters, resulting in muscle weakness, confusion, and paralysis, among other symptoms. Carbaryl is said by EPA to be âone of the most widely applied insecticides in the U.S.,â since use began in 1959, with 10-15 million pounds used annually. It is a broad-spectrum insecticide used on a variety of crops, in forestry and on ornamentals, in […]

(Beyond Pesticides, January 24, 2017) An analysis conducted by scientists at the University of St. Andrews in Scotland is calling into question the conclusions reached in a study conducted by multinational chemical company Syngenta, which indicated that honey bees were not at risk from the widely used neonicotinoid insecticide thiamethoxam. The challenge to the Pilling et al 2013 study is important because while many experiments have been performed in the lab or semi-lab environment, this study was a field experiment developed to test pollinator exposure under normal agricultural conditions. The conclusions of such real-world experiments are weighed more heavily by regulators when making safety and use determinations. St. Andrewsâ scientists focus in on the Pilling et al claim that because its study did not have high levels of replication, that it would have been misleading to perform formal statistical analysis. They respond that this would indeed be the case if Pilling et al had intended on finding statistical significance and concluded that there was no effect based on those tests. However, Syngentaâs scientists instead simply graphed average values over time based on their measurements (measurements such as number of bees in a hive, hive weight, number of brood, etc.), and compared […]

(Beyond Pesticides, January 23, 2017) Last week, the U.S. Environmental Protection Agency (EPA)  released its final Biological Evaluations of Three Chemicalsâ Impacts on Endangered Species, which finds that chlorpyrifos and malathion likely have detrimental effect on 97 percent of all species listed and protected under the Endangered Species Act (ESA), while diazinon adversely affects 78 percent. According to EPAâs release on the subject, this is the âfirst-ever draft biological evaluations analyzing the nation-wide effectsâ of these registered chemicals on endangered species after decades of widespread use. The evaluations stem from a legal settlement with the Center for Biological Diversity (CBD) in which CBD sued EPA in April 2014 for its failure to comply with ESA, which requires the agency to carry out consultations with federal wildlife agencies while registering pesticides. According to Nathan Donley, Ph.D., a CBD senior scientist, âWeâre now getting a much more complete picture of the risks that pesticides pose to wildlife at the brink of extinction, including birds, frogs, fish and plants. When it comes to pesticides, itâs always best to look before you leap, to understand the risks to people and wildlife before theyâre put into use. The EPA is providing a reasonable assessment of those risks, many of which can be […]

(Beyond Pesticides, January 18, 2017) Despite science affirming its hazards, the U.S. Environmental Protection Agency (EPA) has expanded the registration of the toxic herbicide mixture, Enlist Duo, which contains 2,4-D and glyphosate, for use on genetically engineered (GE) cotton and extended its use on GE corn, soybean, and cotton from 15 to 34 states. This approval late last week comes at a time when widespread chemical use is threatening public health and the environment and weed resistance continues to grow, threatening farmers’ productivity and profitability. Over 600 public comments were submitted to EPA on this issue, with many comments vehemently opposing the current uses and the proposed expansion of uses. In its decision, EPA stated that Enlist Duo âmeets the safety standard for the public, agricultural workers, and non-target plants and animal species.â However, as Beyond Pesticides stated in comments to the agency, EPA has not fully considered all the environmental costs, including the cost of tackling increased 2,4-D resistant weeds, crop and non-target damages from uncontrolled drift, as well as unanswered questions regarding synergistic chemical effects in non-plant species. Advocates predict weed resistance to Enlist Duo and have urged EPA to reject its continued use and incentive sustainable organic practices. Additionally, […]

(Beyond Pesticides, January 17, 2017) On January 12, 2017, the U.S. Environmental Protection Agency (EPA) released major risk assessment documents on  pollinator exposure to bee-toxic neonicotinoid insecticides finding no significant risks, despite the large and growing body of science identifying the pesticides’ hazards. In the documents, EPA identifies risks posed to bees by several neonicotinoid insecticides, but suggests that no restriction on uses are imminent. In another decision meant to protect bees from acutely toxic pesticides, the agency is scaling back its original proposal in deference chemical-intensive agricultural interests. EPA’s long awaited pollinator assessments for the neonicotinoids: clothianidin, thiamethoxam, and dinotefuran, much like the 2016 pollinator assessment release for imidacloprid, identifies risks to bees from the agricultural applications (foliar, soil and seed) of these chemicals, including from pesticide drift. Observed effects include decline in worker bees, and subsequent declines in brood and pollen stores in the colony. EPAâs assessments continue to focus on honey bees, with cursory mention of wild, native bees. Once again, the assessments did not consider risks from exposures to contaminated water, guttation droplets, or soil, with EPA stating that, âThe Agency lacks information to understand the relative importance of these other routes of exposures and/or to quantify potential risks […]

(Beyond Pesticides, January 12, 2017) Yesterday marked a monumental event in the fight against pollinator declines, as the rusty patched bumblebee became the first bee species to officially be declared endangered by the U.S. Fish and Wildlife Service (FWS). According to FWS, endangered species designations are made when a species is âin danger of becoming extinct throughout all or a portion of their range.â Tom Melius, Service Midwest Regional Director for FWS, stated in a press release that, when it comes to this determination, â[FWSâs] top priority is to act quickly to prevent extinction of the rusty patched bumble bee. Listing the bee as endangered will help [the agency] mobilize partners and focus resources on finding ways right now to stop the decline.â Listed yesterday in the Federal Register, the ruling will go into effect February 10, 2017. This is a victory for environmental groups who have fought to protect the rusty patched bumble bee from widespread threats, such as habitat loss and pesticide use. According to FWS, the rusty patched bumble bee was once widespread across the United States and parts of Canada, but declined dramatically in the 1990s.  Since then, their populations have dwindled and their overall decline is estimated at 91 […]
