(Beyond Pesticides, November 28, 2018)Â Recent research out of Harvard University and published in the journal Science has demonstrated some of the mechanisms through which exposures to neonicotinoid pesticides harm bumblebee populations. The study found that exposure to imidacloprid, a neonicotinoid â the most widely used category of pesticides worldwide â directly impacts social behaviors in bumblebees. These behaviors have serious effects on the functioning and viability of bee colonies. In the research experiment, worker bees exposed to imidacloprid exhibited reduced general and nurturant activity, and a tendency to locate themselves at the periphery of the nest. The study noted decreased caretaking and nursing behaviors, which in turn harms productivity and thermal regulation in the colony. These tasks are important to colony development; impaired thermoregulation negatively affected the beesâ typical construction of an insulating wax canopy for the nest, and poor caretaking can affect brood growth. Investigators noted that, âNeonicotinoids induce widespread disruption of within-nest worker behavior that may conribute to impaired growth. . . . These changes in behavior acted together to decrease colony viability, even when exposure was nonlethal.â The authors also observed that many of these dysregulated behaviors were more pronounced at night than during sunlight hours, and […]

(Beyond Pesticides, November 27, 2018) The U.S. Environmental Protection Agency (EPA) ignored the input of an expert weed scientist on the controversial herbicide dicamba, bending to Bayerâs Monsanto and the pesticide industry, according to emails obtained by the Arkansas Democrat and Chronicle (ADC) through a Freedom of Information Act request. The scandal centers on the recent re-approval of the pesticide, a highly volatile and drift-prone herbicide that has become a serious problem for many farmers and state regulators. As top-level EPA officials continue to work with industry to subvert their own agencyâs scientific findings, more and more consumers are moving to organic products in order avoid the pesticide risks government regulators ask consumers to accept. Emails ADC received indicate that Jason Norsworthy, PhD, a weed scientist with the University of Arkansas, worked closely with Bayerâs Monsanto in conducting field trials this past summer, but found high volatility and drift of the companyâs new dicamba-based herbicide XtendiMax. The product was developed in the face of widespread resistance to glyphosate-based herbicides in genetically engineered (GE) farm fields. However, recent accounts from farmers in the south and midwest indicate that, not only is the switch to dicamba unhelpful in eliminating drift and reversing escalating weed resistance, its […]

(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. â[Considering] all the threats facing bees,â says study lead author Lewis Bartlett of the […]

(Beyond Pesticides, November 15, 2018) Neonicotinoids are widely known for their link to declining pollinator populations, but new research finds that the ill effects of these chemicals also extends to amphibian populations. In a study published late last month, scientists from the National Wildlife Research Center in Ottawa, Canada found that chronic exposure to real-world levels of the neonicotinoid imidacloprid limits the ability of juvenile wood frogs to escape a predator attack. This research adds additional evidence that neonicotinoids are harming aquatic food chains, and reinforces calls for U.S. regulators to follow the science and adequately restrict these toxic pesticides. Researchers investigated the impact of neonicotinoids on the post-tadpole life stage of wood frogs, which has been identified as critical to sustaining viable populations of the species. Rather than determine acute impacts that assess how lethal a pesticide is, scientists opted to observe how wood frog behavior changes as a result of chronic, real-world exposure scenarios. In particular, scientists sought to figure out whether exposure resulted in an altered behavioral response to the presence of a predator. As tadpoles, wood frogs were chronically exposed to real world levels of imidacloprid (1, 10, and 100 micrograms/liter), while others were left unexposed […]

(Beyond Pesticides, November 14, 2018) Monarch butterflies are in the midst of a staggering decades-long population decline that has rapidly accelerated since 2005, research published by an international team of scientists and the University of Florida last month indicates. According to data meticulously collected by researchers, monarchs making their way to central Florida after emerging from their breeding grounds in Mexico have declined by 80% over the last decade and a half. This is roughly the same time frame at which beekeepers began to see precipitous declines in managed honey bee colonies. Researchers point to industrial development and increasing pesticide use as factors that have accelerated the decline of this iconic species. “A broad pattern is that 95 percent of corn and soybean products grown in the U.S. are Roundup Ready crops that resist glyphosate,” said study coauthor Earnest Williams, PhD, of New Yorkâs Hamilton College in a press release. “That has a national impact. What’s really needed are patches of native vegetation and nectar sources without pesticides. It’s not just for monarchs but all pollinators.” Beginning in 1985, renowned monarch expert Lincoln Brower, PhD and his team monitored monarch populations at a pesticide-free cattle pasture south of Gainesville, FL.

(Beyond Pesticides, November 8, 2018) Two months after publishing its first series of tests, part two of an Environmental Working Group (EWG) study finds residues of Roundupâs active ingredient, glyphosate, in all General Millsâ Cheerios and PepsiCoâs Quaker Oats products sampled. Health advocates are expressing concern about the consequences of chronic glyphosate exposure, and say U.S. federal agencies must limit the herbicideâs use on oat-based breakfast foods regularly marketed to children. In addition, organic itself is under threat, as chemical-intensive management practices undermine the future of the growing organic movement. In this second round of testing, EWG scientists purchased products around San Francisco and Washington DC. 28 samples of conventional and 16 samples of organic oat products were collected. Approximately 300 grams of each General Mills and PepsiCo product were packaged and shipped to Anresco Laboratories, in San Francisco. Detected glyphosate residues were compared to EWGâs own health benchmark of 160 parts per billion (ppb). This benchmark is based on risks of lifetime exposure and what EWG scientists consider allowable and protective of childrenâs health with an adequate margin of safety. EWGâs results detected glyphosate residues in all 28 samples of conventionally grown oat products. The vast majority (all but two) […]

(Beyond Pesticides, November 6, 2018) Scientists working for USDAâs Agricultural Research Service in Lincoln, Nebraska have discovered natural compounds derived from coconut oil that are more effective than DEET at repelling mosquitoes, ticks, biting flies, bed bugs and other insects. Given the long-lasting efficacy of the compounds researchers tested, commercialization could make the regular use of toxic insect repellents, like DEET, obsolete. Advocates are praising USDA researchers for the results, indicating that this is exactly the type of research government agencies should be funding and promoting. It is important to note that USDA scientists did not find coconut oil itself to be an effective repellent. Lab equipment was used to analyze and isolate medium chain fatty acids within coconut oil for their repellent properties. Scientists zeroed in on a blend of C8 (caprylic acid), C10 (capric acid), and C12 (lauric acid) fatty acids as the most effective repellent mixture. Individually, only C12 exhibited anywhere near the same efficacy as the specific blend identified. The study indicates that more research is needed to understand why coconut oil itself was ineffective, and how the synergy between the fatty acid combinations resulted in such effective repellency. To verify their hypothesis on the efficacy […]

(Beyond Pesticides, November 2, 2018)Â A group of leading toxics experts, who published a paper in the journal PLOS Medicine on their research on organophosphate exposure during pregnancy and impacts on child development, are calling for a ban on organophosphate pesticides. The study evaluates current science on the risks of this class of compounds, produced by Corteva Agriscience (formerly Dow AgroSciences); its conclusions warn of the multitude of dangers of organophosphates for children, and makes recommendations for addressing these risks. The experts conclude that: (1) widespread use of organophosphate (OP) pesticides to control insects has resulted in ubiquitous human exposures; (2) acute exposures to OPs is responsible for poisonings and deaths, particularly in developing countries; and (3) evidence demonstrates that prenatal exposures, even at low levels, put children at risk for cognitive and behavioral deficits, and for neurodevelopmental disorders. Among the authorsâ recommendations are these: Governments and subsidiary agencies, including the Environmental Protection Agency (EPA), should phase out chlorpyrifos and other organophosphate pesticides; ban non-agricultural uses of OP pesticides (including in household products); monitor watersheds and drinking water sources of human exposure; promote the use of integrated pest management (IPM) through incentives and training; and establish pesticide use and illness reporting […]

(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 âreproducers,â 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 studyâs 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 25, 2018) A study published last month in Scientific Reports finds that eating sunflower pollen significantly reduces protozoan infection in bumblebees. Studying ecosystem services and what she calls âfloral rewards,â evolutionary ecologist Lynn Adler, Ph.D. at the University of Massachusetts Amherst says sunflowers may provide a long sought after solution for improving beesâ immune system response to both disease and parasites. The researchers studied the protozoan Crithidia bombi, a common parasitic infection of bumble bees, known to impair learning and foraging, shorten lifespan and destabilize colony hierarchies by impacting queen bee behavior. From the outset of the study, Dr. Adler says, âthe more sunflowers were grown at the farm, the lower the Crithidia load for the bees at that farm.â Knowing pollinators eat pollen as a source of protein and healthy fats, Dr. Adler hypothesized that both pollen and nectar might have medicinal effects against disease and parasites. However, her experiment did not show consistent results with nectar. After bees in the lab were starved for 4-6 hours, researchers fed individual worker bees from small colonies a drop of fructose fluid containing 6,000 Crithidia cells, being the approximate concentration bees may encounter in the wild while foraging. After […]

(Beyond Pesticides, October 19, 2018) Pollinator advocates and the Center for Biological Diversity (CBD) are imploring the U.S. Environmental Protection Agency (EPA) to deny Bayer CropScienceâs application for use of âSivanto,âa pesticide product with the active ingredient flupyradifurone, a chemical the company claims is safer for bees, but poses the same risks at the notorious bee-toxic neonicotinoid insecticides. If approved, Sivanto would be sprayed in tobacco-growing states along 300,000 acres in the southeast U.S., areas home to more than three dozen species protected under the Endangered Species Act (ESA). Bayerâs proposal for expanded uses comes after EPAâs own assessment indicated risks to endangered species, and despite the fact that the agency has not undergone an ESA mandated consultation with federal wildlife agencies. For the countless flying insects, birds, and bats already under significant threat from neonicotinoids, adding another systemic insecticide to the mix will only make the situation worse. Bayer AG is characterizing flupyradifurone as being harmless to honeybees. However, flupyradifurone, being a systemic pesticide, can negatively impact many non-target species. In fact, flupyradifurone impacts honey bee brains in a similar way to neonicotinoids, as it impairs learning, memory and the honey beesâ affinity for nectar rewards. Advocates worry that growing […]

(Beyond Pesticides, October 16, 2018) Bacteria exposed to widely used herbicides like Roundup develop antibiotic resistance 100,000 times faster than average, according to new research published by New Zealand scientists in PeerJ. The results have ominous implications for the modern worldâs ability to avert a post-antibiotic era. Even if new antibiotics are discovered, or existing compounds used more judiciously, scientists say that will not be enough to prevent the ongoing crisis – the world is also confronting bacterial exposure to herbicides and other non-antibiotic agents that have the ability to rapidly induce resistance. âHerbicides are among the most widely used and dispersed manufactured products on Earth. Some form of exposure for people, pets and livestock can be routinely expected,â study author Jack Heinemann, PhD, told Newsweek. âMeanwhile, antibiotics are used at high rates particularly on people, pets and livestock. Therefore, the combination of exposures for bacteria that live on us is all but guaranteed.â This current round of research by Dr. Heinemann and his team is the outgrowth of previous studies (1, 2) that established the ability of common herbicides to induce antibiotic resistance in strains of pathogenic bacteria Salmonella eterica and Escherichia coli. Now, the scientists are drilling into […]

(Beyond Pesticides, October 15, 2018) As a leader in organic sales, it is critical that Kroger take additional expedited steps to increase the market share of organic food and eliminate the use of toxic pesticides harmful to public health and the environment. Kroger is among the major food retailers that sells food that has been grown with toxic pesticides, such as the extremely hazardous insecticide chlorpyrifos which causes neurological and brain damage in children. Kroger should immediately end its misleading and fraudulent advertising and labeling of food products as ânaturalâ and replace these with certified organic products. In fact, by misleading consumers with ânaturalâ labeling and advertising of food, Kroger supports chemical-intensive agriculture that poisons children, causes cancer, and threatens biodiversity through the use of toxic chemicals like chlorpyrifos, glyphosate, and neonicotinoids. This is unnecessary and unacceptable. Tell Kroger to stop selling food grown with toxic pesticides. Chlorpyrifos  is a highly neurotoxic organophosphate pesticide that is linked to neurologic developmental disorders in children. Exposure to even low levels of organophosphates like chlorpyrifos during pregnancy impairs learning, changes brain function, and alters thyroid levels of offspring into adulthood. EPAâs own assessment finds that children exposed to high levels of chlorpyrifos have developmental delays, attention problems, attention-deficit/hyperactivity disorder […]

(Beyond Pesticides, October 11, 2018) Healthy, stable populations of bees and butterflies are best preserved in farm fields that are certified organic, according to an extensive, three-year study conducted by Swedish researchers at Lund University. The research, published last month in the journal Biological Conservation, highlights the benefits that organic farms provide pollinators by improving floral resources and forgoing the use of toxic pesticides. The data continues to support the need for a broad-scale conversion to more sustainable organic practices in the U.S. and internationally. âThis is the first large-scale study over the course of several years to show that organic farming has a consistent, stabilizing effect on pollinator diversity,â says Romain CarriĂŠ, PhD, a postdoctoral researcher at CEC. Researchers recorded observations of bumblebees, butterflies and flowering plant species at 10 organic and 9 conventional farms throughout Sweden for three years. Farms were compared across type, including cereal fields, temporary grasslands, and semi-natural grasslands. The study aimed to observe the spatio-temporal aspects (continuity of the number of different species in space and time) of pollinators and flowering species in these fields. Results of the study found that, overall, organic farms had and sustained a higher rate of floral, bee, and butterfly […]

(Beyond Pesticides, October 10, 2018) Nearly one-third of General Mills shareholders called on the company last month to improve product stewardship and eliminate pesticides like bee-toxic neonicotinoid insecticides or the probable carcinogenic weed killer glyphosate from its supply chain. The proposal was put forward by nonprofit organization As You Sow, and Green Century Equity Fund (GCEF), a mutual fund. This is the latest public shareholder action GCEF has made in regards to corporate pesticide reform, with the company previously putting pressure on the Dr. Pepper Snapple Group for its allowance of pesticides within its supply chain. While the actions are encouraging, some advocates are urging shareholder groups to go beyond increased accountability and transparency and push companies to focus on sourcing organic to ensure that no pesticides make their way into food products. The shareholder proposal ultimately garnered support from 31% of General Mills shareholders. âShareholders believe the company can, and should, do more to protect the health of their supply chain and the public from toxic pesticides,â said Christy Spees, environmental health program manager at As You Sow to the StarTribune. The proposal states, âWhile the company asserts that it is currently âdocument[ing] continuous improvementâ concerning environmental impacts from its supply […]

(Beyond Pesticides, October 5, 2018) The Oregon Department of Agriculture (ODA) is temporarily banning the use of any products containing the herbicide aminocyclopyrachlor to rights-of-way after finding widespread tree deaths along a scenic highway that cuts across the center of the state. While Oregon is the first state to ban the chemical, it is not the first instance of the pesticide killing stands of established, otherwise healthy trees. In 2014, chemical company DuPont settled a class action lawsuit totaling over $1.8 million in civil penalties after its aminocyclopyrachlor product Imprelis was cited for misbranding and failure to report adverse incidents of trees dying after applications. Oregon first encountered evidence of abnormal growths, curling, and die-backs of coniferous trees along roadsides back in 2012. A report on tree damage produced by ODA in 2015 narrowed the cause down to the use of aminocyclopyrachlor-based herbicides, including DuPontâs Imprelis, as well as Bayerâs Perspective. At the time, ODA indicated the U.S. Forest Service (USFS) had sent letters to the agency requesting the cessation of aminocyclopyrachlor use along roadsides. Oregon officials indicate that the contractor did stop spraying the chemical in areas cited in the report. An update to the first report, published in […]

(Beyond Pesticides, October 4, 2018) According to new research from the University of Texas at Austin, glyphosate, the worldâs 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 insectsâ 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, September 21, 2018) Monsanto, now an integrated unit of Bayer AG, is asking Superior Court Judge Suzanne Bolanos to reverse the verdict, reduce the award, or grant a new trial for the company after a jury determined that a California groundskeeper contracted non-Hodgkinâs lymphoma from spraying glyphosate for years. Dewayne Johnson, who maintained the grounds of a California Bay-area school district, was awarded $289 million by a jury, which found that Monsanto acted with âmalice or oppression.â Mr. Johnsonâs case was the first of its kind to go to trial â fast tracked based on the severity of his illness â but over 8,000 similar lawsuits are pending in U.S. courts. Bayerâs Monsanto claims that the verdict does not reflect the scientific data. âWhile we are sympathetic to Mr. Johnson and his family, glyphosate is not responsible for his illness, and the verdict in this case should be reversed or set aside,â Bayer said in a September 18 statement. While Bayer contends that glyphosate does not result in individual applicators contracting cancer, this view is at odds with a 2015 designation from the International Agency for Research on Cancer (IARC), which determined the chemical is a probable carcinogen, […]

(Beyond Pesticides, September 12, 2018) The city of Amsterdam, Netherlands is leading global bee recovery efforts by increasing its diversity of wild pollinator species, according to reporting and an analysis by NBC News. A new map published by the city identified 21 bee species not found in an earlier 1998 survey recorded by Amsterdam officials. The increase has been attributed to a range of pollinator-protective measures, including a ban on bee-toxic pesticides and the planting of native flowers, prioritized by the city government since the turn of the century. Local communities throughout the world can look to Amsterdam for policies and practices that will safeguard their own unique pollinator populations. The NBC News report notes several initiatives undertaken by the Amsterdam government. Many of these measures come out of a $38.5 million fund aimed at broadly improving environmental sustainability. “Insects are very important because theyâre the start of the food chain,” said Geert Timmermans, an Amsterdam ecologist to NBC News. “When it goes well with the insects, it also goes well with the birds and mammals.” Insect and bee hotels are often installed in conjunction with the development of green roofs, which are encouraged for all new buildings.

(Beyond Pesticides, September 5, 2018) Local Limits on Spraying Monsantoâs Toxic Weed Killer in Parks, Playgrounds, and Schoolyards. More than 50 city and county ordinances banning the use of the toxic weed killer glyphosate on local playgrounds, parks and schoolyards could be overturned by a provision championed by House Republicans in their version of the farm bill, a Beyond Pesticides and EWG analysis found. A four-page provision tucked away in the 748-page farm bill passed by the U.S. House of Representatives in June would likely preempt local governments from adopting their own pesticide regulations, including ordinances that prohibit the use of glyphosate, the active ingredient in Monsantoâs Roundup, in parks and playgrounds. Beyond Pesticides found that 58 local ordinances ban the use of glyphosate. Overall, 155 local ordinances that regulate the use of toxic chemicals in parks and playgrounds could be preempted by Sec. 9101 of the Houseâs farm bill. Glyphosate is classified by the state of California as a chemical known to cause cancer, and as a probable carcinogen by the World Health Organization. Earlier this month, a San Francisco jury ordered Monsanto to pay $289 million to a school groundskeeper who said years of working with Roundup caused his terminal cancer. […]

(Beyond Pesticides, September 4, 2018) Close on the heels of the recent landmark California decision against Monsanto, maker of the glyphosate-based pesticide Roundup, Vietnam has demanded that the company pay damages to the many victims of its Agent Orange herbicide and defoliant, which Monsanto supplied to the U.S. military during the Vietnam War. (Monsanto was not the only U.S. manufacturer of the compound; there were nine in total.) U.S. forces, in a program dubbed Operation Ranch Hand, used more than 13 million gallons of the compound in Vietnam â nearly one-third of the 20 million gallons of all herbicides used during the war in Laos, Cambodia, and Vietnam. In Vietnam alone, 4.5 million acres were impacted by Agent Orange. Nguyen Phuong Tra, a spokesperson for Vietnamâs foreign ministry, said, âThe [U.S.] verdict serves as a legal precedent which refutes previous claims that the herbicides made by Monsanto and other chemical corporations in the U.S. and provided for the U.S. army in the war are harmless. . . . Vietnam has suffered tremendous consequences from the war, especially with regard to the lasting and devastating effects of toxic chemicals, including Agent Orange.â Around the world, the U.S. case may be sparking […]

(Beyond Pesticides, August 31, 2018) Given the choice to forage on untreated or pesticide-contaminated food sources, bees will increasingly choose the pesticide, according to research published in Proceedings of the Royal Society B in late August. The data indicate that risks to pollinators grow, rather than wane, over time, making improved regulation over bee-toxic neonicotinoid pesticides even more climacteric. In essence, the study indicates that bees may be undertaking the human equivalent of chain-smoking themselves to death. Authors of the study note that numerous studies have been performed that subject bees to neonicotinoid-treated food, however this research generally allows pollinators to only forage on contaminated sources. While this provides important information on hazard criteria, it does not indicate risk of exposure. Positing the idea that pollinators may eventually seek to avoid neonicotinoid-contaminated nectar, researchers provided bumblebee colonies with a choice over the course of 10 days. At the start, the bees exhibited no discernable preference between toxic and nontoxic food. However, as time went on more and more bees fed from nectar laced with thiamethoxam, a widely used neonicotinoid. By the end of the experiment, food containing 2 parts per billion of the pesticide was eaten 10% more than in […]

(Beyond Pesticides, August 27, 2018)Â 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 worldâs 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 â and thus, to those ecosystem services â 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 […]
