(Beyond Pesticides, November 21, 2018) A study published last month in the Journal of Apicultural Research finds significant numbers of U.S. honey bees at risk after exposure to hazardous synthetic pesticides intended to control mosquitoes. With many beekeepers rarely given warning of insecticide spraying, researchers say the risk of losing colonies could increase. Advocates say fear of Zika and other mosquito-borne illnesses could result in counterproductive and reactionary insecticide spraying that will add further stress to managed and native pollinators already undergoing significant declines. Researchers aimed to determine whether neighboring honey bee colonies could be similarly affected by aerial insecticide spraying. To calculate the percentage of colonies that could be affected, density of honey bee colonies by county was compared with projections of conditions thought to be prone to regional Zika virus outbreaks. Researchers found 13 percent of U.S. beekeepers at risk of losing colonies from Zika spraying. In addition, it was determined that many regions of the U.S. best suited for beekeeping are also those with favorable conditions for Zika-prone mosquitoes to proliferate. These regions include the southeast, the Gulf Coast, and California’s Central Valley. “[Considering] all the threats facing bees,” says study lead author Lewis Bartlett of the […]

(Beyond Pesticides, November 1, 2018) A new study offers fresh evidence that wild bumblebee pollinators are particularly vulnerable to the impacts of neonicotinoid (neonic) insecticides, finding that exposure to these compounds interferes with mating success and population stability. Researchers from Worcester Polytechnic Institute in Massachusetts, measuring real-world harms of neonicotinoids, indicate that the impacts they found to bumblebee “reproducers,” namely queen and drone (male) bees, does not bode well for the array of plant species that relies on them. Though advocates warn that destabilizing managed pollinators could threaten U.S. food production and exports, with food prices increasing as cost of bringing pollinators to farms increases, the study’s authors and advocates insist that the impacts of such widespread poisoning of wild bees could be felt well beyond agriculture. Researchers in the lab compare behavioral and psychological responses of virgin queens, workers, and male Bombus impatiens from multiple colonies to field-realistic doses of the neonicotinoid clothianidin. While every bee was given a replenishing supply of pollen based on body weight and energy demands, four distinct concentrations of diluted analytical-grade (pure) clothianidin (including a control with no pesticide added) were mixed into a nectar-like solution and fed to the bumblebees orally for 5 […]

(Beyond Pesticides, October 4, 2018) According to new research from the University of Texas at Austin, glyphosate, the world’s most widely used agrichemical weed killer, may also be killing bees by impairing their gut microbiota, and subsequently, their immune systems.  The study, published in the journal Proceedings of the National Academy of Sciences, titled Glyphosate perturbs the gut microbiota of honey bees, notes these findings as evidence glyphosate could very well be contributing to the sharp decline of pollinators seen throughout the world over the past decade. Researchers began with a single hive and collected several hundred worker bees. One group of bees was fed a sterile sugar syrup, while others were exposed to levels of glyphosate equal to what is found in conventional crop fields, lawns and highway medians. To aid tracking and recapture, bees were marked with colored dots based on their grouping. Researchers sampled 15 individuals from each group of worker bees right before and three days after reintroduction back to the hive. At both times, DNA from the insects’ guts was extracted to observe whether glyphosate had significantly altered microbial diversity within their organ system. Results found relatively minimal impacts to bees tested prior to their […]

(Beyond Pesticides, August 27, 2018) Beyond the visual and audial charms of some bird species, insect-eating birds play a significant role in controlling pests that can ruin crops or ravage forests. A meta-study by Martin Nyffeler, Ph.D. of the University of Basel in Switzerland finds that globally, birds annually consume 400-plus million metric tons of various insects, including moths, aphids, beetles, grasshoppers, crickets, and other arthropods (invertebrate organisms with exoskeletons, paired and jointed appendages, and segmented bodies, such as insects, crustaceans, and spiders). This research reviews 103 studies that examine the volume of insects consumed by various birds in seven of the world’s major biomes. In consuming such volumes of insects that can inflict damage on crops, trees, and other plants on which organisms may feed or otherwise depend, birds provide significant services to ecosystems, to denizens of habitats, and to human food system and economic interests; they also keep local ecosystems in balance. Threats to birds — and thus, to those ecosystem services — include those from pesticide use. Of the 10,700 known bird species distributed across the planet, more than 6,000 are primarily insectivorous. The study indicates that forest-dwelling birds consume the majority of insects (approximately 300 million metric […]

(Beyond Pesticides, February 8, 2018) New trials are being launched in the United Kingdom (UK) to monitor fields that have long strips of wildflowers planted through croplands to boost natural predators and potentially reduce pesticide spraying. The large-scale trials are meant to determine how effective these strips can be as a tool for practitioners wishing to enhance biological pest control in the field. The field trials, carried out by the Centre for Ecology and Hydrology (CEH), are being conducted on 15 large arable farms in central and eastern England and would be monitored for five years. Until now, wildflower strips have been placed at the edge of fields as refuges. However, natural predators in these strips would be unable to access the center of large planted fields, and thereby unable to effectively target pests that are in the fields. In the new trials, six-meter wide strips of annual wild and cultivated plants – with 13 to 16 species – will be planted 100 meters apart so that predators will be able to attack aphids and other pests typically found in fields. The researchers at CEH’s ASSIST program (Achieving Sustainable Agricultural Systems) will determine whether in-field strips are feasible tools for […]

(Beyond Pesticides, December 1, 2017) Ichneumonid wasps (family Ichneumonidae), are a widely distributed parasitoid wasp family within the order Hymenoptera. The name “ichneumonid” comes from Greek words meaning “tracker” and “footprint.” And females do indeed hunt for suitable “hosts” by first identifying the organism’s food source. Once a suitable host is found, females deposit eggs onto the unsuspecting insect larvae where, within ten days to several weeks, the Ichneumonid larva kills the host by feeding on its body fluids before it emerges. They are also known as “scorpion wasps” for the extreme length and curving motion of their segmented abdomens. Note: both adult males and females are stingless, and feed on nectar. The discovery of Ichneumonidae was so troubling to many that, in 1860, Charles Darwin wrote a letter to the American naturalist Asa Gray, saying: “I own that I [should wish to] see as plainly as others do…evidence of design and beneficence on all sides of us…I cannot persuade myself that a beneficent and omnipotent God would have designedly created the Ichneumonidae with the express intention of their feeding within the living bodies of Caterpillars, or that a cat should play with mice.” The parasitic behavior of Ichneumon wasps was […]

(Beyond Pesticides, November 28, 2017) Bumblebees exposed to field-realistic levels of neonicotinoid insecticides have problems with “buzz pollination” that results in reduced pollen collection, according to new research published in Scientific Reports. This is the latest science to tease out the complex ways in which neonicotinoids interfere with these important pollinators, providing yet another reason to eliminate these highly toxic, systemic insecticides from the environment. Flowers that bumblebees pollinate require the insects to emit soundwaves, or ‘sonicate’ to release their pollen, and bumblebees must perfect their techniques over time in order to maximize the pollen they are able to collect. Researchers tested the effect of neonicotinoids on bumblebees’ sonication abilities by exposing them to field realistic doses of the insecticide thiamethoxam at rates of 2 parts per billion (ppb) and 10 ppb, and observing their ability to successfully collect pollen. A control group that never came in contact with thiamethoxam was also used to compare the progress of the exposed group. Lead author of the study, Penelope Whitehorn, PhD, indicated, “We found that control bees, who were not exposed to the pesticide, improved their pollen collection as they gained experience, which we interpreted as an ability to learn to buzz […]

(Beyond Pesticides, October 4, 2017) Beetles in the family Cantharidae are known as soldier beetles, a name that is based on the resemblance of the elyra (wing cover) to certain military uniforms. They superficially resemble fireflies (family Lampyridae), but lack light-emitting organs and the covering obscuring the head of fireflies. Like fireflies, soldier beetles are distasteful to most predators. Range There are 16 genera containing 455 species of soldier beetles native to North America, including Chauliognathus marginatus, which is commonly seen on goldenrod in late summer and early fall. Worldwide, there are about 5,100 species in 160 genera, widely distributed in all but polar regions. Most frequently active in summer and early fall, adults can be found on various flowers including sunflowers, tansy, zinnia, marigold, goldenrod, and coneflower. Females lay eggs in clusters in the soil. Larvae are mostly carnivorous, feeding on soil insects. They live through the winter under loose soil, and become active during spring. Larvae normally pupate in early summer and adults first emerge in mid-summer. Physiology The soldier beetle’s body is around ½ to ¾ inch long. Adults are black or brown, usually with red to yellow markings, an “aposematic” signal to predators, warning of an […]

(Beyond Pesticides, July 21, 2017) A March 2017 review of studies on the agricultural use of glyphosate (the active ingredient in “Roundup” and other formulated herbicides) points to widespread persistence in soils subject to long-term, intensive glyphosate use, and myriad resulting concerns about impacts on soil and environmental health. The review, by Robert J. Kremer, PhD, of the University of Missouri School of Natural Resources, cites concerns that include: reduction of nutrient availability for plants and organisms; disruption to organism diversity, especially in the areas around plant roots; reductions of beneficial soil bacteria; increases in plant root pathogens; disturbed earthworm activity; reduced nitrogen fixing at plant roots; and compromised growth and reproduction in some soil and aquatic organisms. Globally, glyphosate is the most widely used herbicide compound: in 2017, worldwide use is estimated to be approximately 1.35 million metric tons. Use in the U.S. has risen dramatically — from 2.72–3.62 million kg in 1987 to approximately 108 million kg in 2014, and 15-fold since 1996, when genetically engineered (GE) glyphosate-tolerant crops were introduced. Use has grown for a number of reasons, including more-intensive use as resistance to the herbicide grows. Researchers have found that, after years of consistent application to […]

(Beyond Pesticides, March 24, 2017) On March 21, the rusty patched bumblebee’s path to protection cleared political hurdles this week. The Fish and Wildlife Service (FWS) on March 21 officially listed the rusty patched bumblebee under the Endangered Species Act (ESA), after months of turmoil due to the Trump Administration’s temporary freeze on federal regulations adopted at the end of the Obama Administration. This listing stands as a landmark decision, marking the rusty patched bumblebee the first bumblebee species, and first bee overall in the continental U.S., to officially be declared endangered by FWS. In October 2016, FWS listed seven species of bees as endangered in Hawaii. The initial decision to list the rusty patched bumblebee as an endangered species came at the very end of President Obama’s term, on January 11, to take effect in February. FWS said in its news release, “Causes of the decline in rusty patched bumble bee populations are believed to be loss of habitat; disease and parasites; use of pesticides that directly or indirectly kill the bees; climate change, which can affect the availability of the flowers they depend on; and extremely small population size. Most likely, a combination of these factors has caused the decline in rusty patched […]

(Beyond Pesticides, March 1, 2017) The Fig wasp is the pollinator of the month for March. A highly evolved pollinator crucial to the life cycle of the fig tree, the fig wasp is part of the chalcidoid family. Within this classification, it is a member of the agaonidae sub family, which consists of both mutualistic pollinating, and parasitic, non-pollinating, fig wasps. Fig wasps have a mutually beneficially relationship with fig trees, as both the tree and the wasp rely on each other for reproduction. According to the Encyclopedia Britannica, there are about 900 species of pollinating fig wasps that are responsible for pollinating 900 different fig tree species. The relationship between fig trees and fig wasps is so evolved that each type of fig wasp pollinates only one specific type of fig tree, creating a beautiful and interdependent evolutionary partnership. Range The range of the fig wasp is dependent on the range of fig trees, which, according to the Encyclopedia of Life, are mainly found in the tropical and subtropical areas of the southern hemisphere. The most widely known fig tree, the common fig tree, or Ficus carica, is native to southwest Asia and the Mediterranean, and range anywhere from […]

(Beyond Pesticides, February 14, 2017) Less than one month after the Rusty Patched Bumblebee’s listing as ‘threatened’ under the Endangered Species Act (ESA) by the U.S. Fish and Wildlife Service (FWS), the Trump Administration has reversed the order. On his first day in office, President Trump issued a memo instructing federal agencies to postpone the effective date of any regulations that had been published in the Federal Register, but not yet in effect. This order means that despite FWS’ determination that without federal action the species will likely become endangered, the Trump administration has 60 days to evaluate the decision for the purpose of “reviewing questions of fact, law, and policy.” Advocates for the imperiled species are urging the administration to allow the Rusty Patched Bumblebee to officially become the first bumblebee federally recognized under ESA. Although the Rusty Patched was once widespread throughout the United States and parts of Canada, it declined dramatically in the 1990’s, and now their populations are estimated to be less than 10% of what they once were.  On its website, FWS lists a number of threats to the Rusty Patched, including pesticides, habitat loss, disease, climate change, and intensive farming practices. Insecticides known as neonicotinoids, […]

(Beyond Pesticides, February 10, 2017) On Wednesday, the Natural Resources Defense Council (NRDC), along with Public Citizen and the Communications Workers of America, sued the Trump administration in the U.S. District Court for the District of Columbia in an attempt to block an executive order (EO) mandating that federal agencies zero out costs to regulated entities, while ignoring benefits to the public, environment, and natural resources. The so-called “Two for One” order requires agencies to propose the repeal of two regulations for every new regulation that is proposed. The Executive Order in question mandates that new rules have a net zero cost to regulated entities in fiscal year 2017, with no mechanism for taking into account the value of benefits they provide in the form of public protection. According to the complaint, “the Executive Order directs agencies to disregard the benefits of new and existing rules—including benefits to consumers, to workers, to people exposed to pollution, and to the economy—even when the benefits far exceed costs. The Executive Order’s direction to federal agencies to zero out costs to regulated industries, while entirely ignoring benefits to the Americans whom Congress enacted these statutes to protect, will force agencies to take regulatory […]

(Beyond Pesticides, February 3, 2017) The Ruby Throated Hummingbird is the pollinator of the month for February. Hummingbirds are nature’s most nimble of birds. They are so quick and agile that most of the time all you’ll see is a flash of red and green before realizing you just encountered a Ruby Throated Hummingbird. This month’s pollinator is the most abundant species of hummingbird on the eastern half of North America. They are named after the coloration of ruby red feathers around their throat. Range The Ruby Throated Hummingbird is the most populous hummingbird found east of the Mississippi. They enjoy mild habitats such as pine and deciduous forests, and can also be found zipping around urban and suburban gardens and orchards.  Ruby Throated Hummingbirds “winter,” meaning they migrate to warmer parts of the globe during the colder winter months. They typically spend that time in parts of Central America and southern Mexico, but have been known to travel as far south as Costa Rica and the West Indies, according to Animal Diversity Web. They will often migrate without stopping, traveling distances as great as 1,600 km in one trip.  According to the Encyclopedia of Life, the hummingbird’s mating grounds are typically east of the 100th meridian in the […]

(Beyond Pesticides, February 1, 2017) Last week in North Miami, the City Council took a significant step that could reduce pesticide use in the community. The Council adopted an Integrated Pest Management (IPM) policy modeled after a plan developed by San Francisco in the mid-90’s. The plan does not ban pesticides and herbicides, but instead aims to reeducate citizens and county workers on least-toxic pest management strategies with the goal of eliminating toxic pesticide use on city property.  The IPM plan does not address pesticide use on private property, due to state preemption of local authority. With the passage of the North Miami’s resolution, city operatives will now be asked to give preference to available, safe and effective non-pesticide alternatives and cultural practices. As stated in the resolution’s Integrated Pesticide Management Program Guidelines, the goal of the policy is “to eliminate the application of all Toxicity Category I and Category II pesticide products by January 2018.” On top of eliminating certain pesticide categories, the resolution also calls for staff training and expert consultants, both of which have the potential to help ease the transition in pursuit of the 2018 goal, and priority will be given to efforts to reduce or eliminate pesticide use near […]

(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 “in danger of becoming extinct throughout all or a portion of their range.” Tom Melius, Service Midwest Regional Director for FWS, stated in a press release that, when it comes to this determination, “[FWS’s] 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.” 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 […]

(Beyond Pesticides, December 24, 2016) Beyond Pesticides thanks our members and supporters for being a part of a critical movement to advance sustainable and organic land and building management in 2016. As our Daily News takes a holiday break, returning Tuesday, January 3, 2017, we hope you will join us in reflecting on the progress made this year, and the critical challenges that lie ahead. The road ahead We are entering a period in our nation’s history with many serious concerns about the protection of public health and the environment. We have heard the President-elect’s rhetoric about the overreach of the Environmental Protection Agency (EPA), the burden of regulatory compliance, and the need to dismantle environmental programs. The nominee for EPA Administrator is on record as challenging science and the value of environmental protection. In contrast, we have learned over the last several decades that protection of the environment contributes to a productive economy and healthier people. Beyond Pesticides’ databases track the scientific literature on pesticide hazards and alternatives, which clearly document the value of healthy ecosystems in providing ecosystem services that translate to reduced costs for farmers and land managers. Whether we’re talking about bees and other pollinators or predator insects, […]

(Beyond Pesticides, December 23, 2016) The Environmental Agency (EPA) has finalized a proposal to ban 72 inert (or secret hazardous) ingredients from use in pesticide formulations following a long fight with environmentalists who, in 2006, asked that pesticide product labels disclose any of 371 inert ingredients that could be in products. While this finalization is a step in the right direction, ultimately the move is viewed by advocates as inadequate. The original petition, submitted by Northwest Coalition for Alternatives to Pesticides, along with Beyond Pesticides, Physicians for Social Responsibility, and nearly 20 other organizations, called on the agency to require disclosure of inerts. To put the announcement in perspective, EPA is acting on 72 inert ingredients that are no longer being used, such as turpentine oil, and nitrous oxide. An inert ingredient is defined as any ingredient that is “not active,” or specifically targeted to kill a pest. According to a 2000 report produced by the New York State Attorney General, The Secret Ingredients in Pesticides: Reducing the Risk, 72 percent of pesticide products available to consumers contain over 95 percent inert ingredients and fewer than 10 percent of pesticide products list any inert ingredients on their labels. The report also found […]

(Beyond Pesticides, May 25, 2016) New York City’s Prospect Park is bringing in a herd of goats to fight back opportunistic species that are encroaching in an area of the park after damage caused by Hurricane Sandy. Rather than spray toxic weed killers like 2,4-D, triclopyr, or glyphosate, the Prospect Park Alliance used the grant money it obtained from the National Park Service to bring in these 4-legged weed warriors as a safe and environmentally friendly way to restore storm-damaged areas. “We are pleased to welcome these goats to Prospect Park to help us further the important woodland restoration work that has always been a focus for the Alliance,” Prospect Park Alliance President Sue Donoghue said to ABC7. “These goats will provide an environmentally-friendly approach to our larger efforts, which will not only beautify the Park, but make it more resilient to future storms.” After Hurricane Sandy barreled up the east coast, a roughly 1.5 acre area of Prospect Park was seriously damaged, with 100s of trees toppled. The disturbance has allowed so-called invasive species to move into the park, supplanting the regrowth of native species in the last remaining forested area in the borough of Brooklyn. Goats act as […]

(Beyond Pesticides, March 1, 2016) Under the terms of an agreement reached lasted month, the U.S. Fish and Wildlife Service (FWS) will begin studying the effects of four commonly used herbicides on the health of 1,500 endangered species in the United States. Based on the terms of the settlement, the result of a series of lawsuits launched by the Center for Biological Diversity (CBD), FWS must develop a  plan to mitigate the effects of glyphosate, atrazine, and its chemical cousins propazine and simazine, on any threatened or endangered species. “This agreement will result in long-overdue protections for our country’s most endangered species,” said Brett Hartl, endangered species policy director at CBD. “Once the Fish and Wildlife Service completes its analysis, and the public finally learns just how toxic and deadly these pesticides are to endangered species, we hope that the government will ultimately take most of these products off the shelf.” Under the Endangered Species Act (ESA), the Environmental Protection Agency (EPA) is required to consult with FWS and the National Marine Fisheries Service (NMFS) on the impacts of pesticides on endangered species when it registers a chemical under federal pesticide law (the Federal Insecticide Fungicide and Rodenticide Act, or […]

(Beyond Pesticides, February 8, 2016) A recent study has revealed that a decrease in soil biota, resulting from an increase in arid zones due to climate change, impacts the services that soil provides, from decomposition of organic matter to nutrient cycling and carbon fixing. “As the  aridity of soils goes up, the microbial diversity and abundance is reduced,” Brajesh Singh, Ph.D., a professor at Western Sydney University and an author of the paper, said. “As the soils’ multi-functions are reduced, so there are social and economic consequences.” Unfortunately, climate change is not the only cause for concern.  Studies have shown that conventional agriculture, intrinsically linked with the dependence on  pesticides, can also reduce diversity in soil biota. The study, published in Nature Communications, used two large-scale databases with contrasting geographic coverage (from 78 global drylands and from 179 locations across Scotland) and found that soil microbial diversity  positively relates to multi-functionality in terrestrial ecosystems. Put simply, when soil diversity is high, the soil can function more efficiently and provide a multitude of ecosystem services. The researcher’s models indicate that microbial diversity was as important as or more important than other multifunctionality predictors, such as mean annual temperature and altitude in […]

(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 […]
