(Beyond Pesticides, September 16, 2024) After the release of a hard-hitting study last week published in Science that pinpoints the cycle of increasing pesticide use with ecosystem and bat decline, resulting in higher infant mortality, Beyond Pesticides is calling for state and local action to transition public land to organic practices. Without a healthy ecosystem, the study documents increased pesticide use with dramatic adverse health effects. To take corrective action, Beyond Pesticides’ action asks governors and mayors to do the following: Eliminate the use of pesticides that imperil bats by adopting biodiversity conservation goals including— (1) ecological mosquito management with measures that recognize the benefit of preventive strategies, establish source reduction programs to manage breeding sites on public lands, educate on the management of private lands, employ programs for larval management with biological controls, and eliminate the use of toxic pesticides; (2) prohibition of systemic insecticides and treated seeds, including neonicotinoids; and (3) land management on public lands—including hospitals, higher education institutions, schools, and parks—using regenerative organic principles and organic certified practices and products, to transition to a viable organic system that prioritizes long-term health of the public, ecology, and economy. The new research connects declines in bat populations with increased […]

(Beyond Pesticides, September 10, 2024) Results from a natural experiment, published in Science, shows ecosystem disruption of bat populations with cascading impacts on human health. Eyal Frank, PhD, an assistant professor of the Harris School of Public Policy at the University of Chicago, links increased insecticide use in croplands in the absence of bat species to a rise in infant mortality. As Dr. Frank says in an article in Science Daily, “[B]ats do add value to society in their role as natural pesticides, and this study shows that their decline can be harmful to humans.” Many farmers rely on bats as alternatives to pesticides to protect their crops from insects, but White-Nose Syndrome (WNS) has greatly impacted bat populations since 2006. With the collapse of many bat populations in counties in North America, these farmers turn to toxic chemicals to replace the ecosystem services bats usually provide. These chemicals, however, lead to ripples through the ecosystem and endanger human health. WNS is an invasive fungus (Pseudogymnoascus destructans) found in caves that affects bats during hibernation. As highlighted in an article in the New York Times, three species of bats in North America have been decimated by this syndrome, and bats […]

(Beyond Pesticides, September 9, 2024)  Comments are due by 11:59 PM EDT on September 30, 2024. With the opening of the public comment period on organic standards that determine the integrity, strength, and growth of the organic agricultural sector, a study was released last week that shows degradation of the ecosystem linked to increased infant mortality associated with higher pesticide use by chemical-intensive farmers compensating for losses in bat populations. It is well known that bats, among other wildlife including birds and bees, provide important ecosystem services to farmers by helping to manage pest populations and increase plant resilience and productivity. While degradation of ecosystems is attributable to many factors, pesticide use accounts for an important element in harm to bats and biodiversity. The study, “The economic impacts of ecosystem disruptions: Costs from substituting biological pest control,” published in Science, concludes with a finding that “insect-eating bat population levels induce farmers to substitute with insecticides, consequently resulting in a negative health shock to infant mortality.” Daily News will cover this study in depth in an upcoming edition. According to research published in the Journal of the Association of Environmental and Resource Economists (2022), bat population declines cost American farmers as much as […]

(Beyond Pesticides, June 20, 2023) Welcome to National Pollinator Week, during which time we recognize—and take action to protect—this important ecosystem link. Pollinators—bees, butterflies, birds, bats, and other organisms—make a critical contribution to plant health, crop productivity, and the preservation of natural resources, but their existence is threatened by their pesticide-contaminated habitat.  Check out this week’s calendar of activities and actions below! On social media, we will be featuring Pollinator Artwork submitted by the community, as well as the numerous cute (and “not so cute!”) pollinators that live in the world around us!  Also, check out our live Pollinator Poll! Follow us and like our page on Facebook, Twitter, Instagram and LinkedIn! Monday: Juneteenth and Environmental Justice As Pollinator Week launches with the celebration of Juneteenth, it is time to renew our commitment to environmental justice while seeking the adoption of transformational policies and practices that recognize the urgency to address disproportionate harm inflicted by toxic pesticide use.  Those fighting for environmental justice understand that the harms inflicted by toxic chemical production and use cause disproportionate adverse effects on people of color—from fenceline communities near chemical production plants to the hazardous and inhumane working conditions in agricultural fields, to […]

(Beyond Pesticides, May 18, 2022) Bat population declines are costing American farmers as much as $495 million each year, finds research published this month in the Journal of the Association of Environmental and Resource Economists. Since 2006, a devastating fungal pathogen known as  Pseudogymnoascus destructans has torn through U.S. bat populations, causing a disease known as White Nose Syndrome that has killed over 90% of northern long eared, little brown, and tricolored bats. As researchers try to get a handle on the devastating and rapidly spreading disease, the effects are becoming apparent in agriculture as farmers lose their critical ecosystem services. “Lost bat populations have harmful ripple effects on food and agriculture,” says study coauthor Amy Ando, PhD. “Crop yields fall and input costs rise as farmers try to compensate for the services bats usually provide. That drives down the value of farmland and the number of acres planted, and the supply shock probably also hurts consumers as ag production becomes more costly.” White nose syndrome and its fungal pathogen were first discovered in a cave in New York in the mid-2000s, having likely traveled from Europe on the gear of a hiker or spelunker. The syndrome is characterized by […]

The organic solutions to problems highlighted in the latest issue of Pesticides and You—based on the importance of healthy ecosystems and public health protection—are within reach, and the data creates an imperative for action now that phases out pesticides within a decade, while ensuring food productivity, resilient land management, and safe food, air, and water. (Beyond Pesticides, April 15, 2022) The current issue of Pesticides and You, RETROSPECTIVE 2021: A Call to Urgent Action, is a look at a year of science, policy, and advocacy that informs both the existential problems that the U.S. and the world are facing due to toxic pesticide dependency, and solutions that can be adopted now. The information in this issue captures the body of science that empowers action at the local, state, and federal level, and provides a framework for challenging toxic pesticide use and putting alternatives in place. The issue finds that 2021 was a pivotal year in both defining the problem and advancing the solution. This year in review is divided into nine sections that provide an accounting of scientific findings documenting serious pesticide-induced health and environmental effects, disproportionate risk to people of color and those with preexisting conditions, regulatory failures, at the same time […]

(Beyond Pesticides, September 29, 2021) Bats foraging in chemical-intensive banana plantations have much less gut diversity than bats foraging in organic banana fields and natural forestland, finds research published this month in the journal Frontiers in Ecology and Evolution. Although there is increasing recognition that a diet of conventional, chemically grown food leads to adverse disruptions of the gut microbiome (also known as dysbiosis), little research has been conducted on the effect of production practices on the gut of wild foraging species. According to the present study there are significant differences that regulators must begin to account for in pesticide risk assessments, and consumers should consider when making choices at the supermarket. Researchers focused their investigation on Pallas’s long-tongued bat (Glossophaga soricina), a nectar feeding bat native to Central and South America. The bat is highly adapted to human environments, sustaining populations in both conventional and organic banana plantations, as well as surrounding forest land. For the study, researchers trapped nearly 200 bats across the country of Costa Rica over a 22-month time span. After trapping, physiological characteristics, like size and body weight, were measured, and bat guano was analyzed for its microbial population. All sampled bats were released back […]

(Beyond Pesticides, March 19, 2021) As reported by VTDigger, Vermont’s Endangered Species Committee recently took action to uphold the state’s endangered species law. The committee announced that a mosquito control program in the Champlain Valley, which uses the toxic pesticides malathion and permethrin, is threatening five species of endangered bats — all of which are on Vermont’s list of threatened and endangered species. The committee voted unanimously to recommend to the state Secretary of the Agency of Natural Resources that the spraying program in the Brandon, Leicester, Salisbury, Goshen, Pittsford Insect Control District be allowed only via special permit. Learn about safer mosquito management and insect-borne diseases at Beyond Pesticides website pages. The bats inhabit the Insect Control District’s five towns, which are host to important feeding habitat for these creatures, as well as maternal roosting colonies where baby bats are born and raised during the months when the pesticides are typically sprayed. In addition, the nighttime spraying of these compounds along 190 miles of road in these communities hangs in the air for hours, putting nocturnally active bats — who fly through the toxic mist or consume insects contaminated with the chemicals — at risk. Mason Overstreet of Vermont […]

(Beyond Pesticides, December 10, 2020) A new test developed by a team of Mexican and Canadian scientists will help field researchers detect early warning signs of pesticide exposure in wild bat populations. There are relatively few studies on the effects of pesticide exposure on bat populations, the authors note in a study published in Environmental Toxicology and Chemistry, but there is considerable need to monitor the health of these important species. “Access to resources might be limited for institutions with less financial support such as conservation NGOs and researchers in developing countries,” said co-author Natalia Sandoval-Herrera, PhD. “The use of early warning biomarkers such as genotoxic effects are most needed in these regions, where the use of pesticides is extensive and there is high biodiversity.” The test in question is referred to as a micronucleus test. Although it does not measure the level of pesticide contaminating a bat’s body, it can assess genotoxicity (the effect of pesticides and other chemical agents that damage genetic information in a cell). This is done by taking blood samples of bats, and testing for the presence of micronuclei formation, which are materials in blood that contain damaged chromosomes not incorporated into a cell after […]

(Beyond Pesticides, April 29, 2020) The terrible reputation with which bats are commonly saddled — especially now, because of their association with the origins of the family of coronaviruses — is undeserved. These nocturnal insect vacuums are fascinating, flying mammals that are under-appreciated, not least for their performance of important services for ecosystems, and for human health and agriculture. Investigators from Israel’s Ben-Gurion University and the Section for Evolutionary Genomics at Copenhagen’s Natural History Museum recently published a study demonstrating that bats can be a mighty tool against pests that damage cotton crops. Bats’ pest control services — relatively invisible because they do their insect marauding at night when humans are not watching — represent an excellent, nontoxic, biological control for some agricultural pests, as well as for mosquitoes that may be human disease vectors. Advocates say that these services should be well considered before any decision to use toxic pesticides that can harm bats, as Beyond Pesticides has covered. The study, “An appetite for pests: Synanthropic insectivorous bats exploit cotton pest irruptions and consume various deleterious arthropods,” was published in Molecular Ecology. [Note: “synanthropic” species are those plants or animals that live near, and benefit from, association with humans […]
