(Beyond Pesticides, January 27, 2021) Lowest ever recorded! That’s the result of a yearly winter monarch count along the California coast, overseen each year by the conservation group Xerces Society. In 2020, citizen scientists counted only 2,000 butterflies. The findings indicate that many on the planet today are likely to experience, within their lifetimes, a world where western monarchs are extinct—unless the federal government acts now. Western monarchs migrate from the Pacific Northwest to overwintering grounds along the California coast, where they remain in relatively stationary clusters that are easy to count.  In the 1980s, roughly 10 million monarchs overwintered along the coast. By the 1990s, that number fell into the low single digits, roughly 1.2 million. Five years ago counts were at roughly 300,000. By 2019, numbers crashed below 30,000. This year’s count saw no monarchs at iconic overwintering sites like Pacific Grove. Other locations, like Pismo State Beach Monarch Butterfly Grove and National Bridges State Park saw only a few hundred. “These sites normally host thousands of butterflies, and their absence this year was heartbreaking for volunteers and visitors flocking to these locales hoping to catch a glimpse of the awe-inspiring clusters of monarch butterflies,” said Sarina Jepsen, […]

(Beyond Pesticides, November 19, 2020) A new study by researchers at the University of California, Santa Barbara (UCSB) finds that crop diversity in commercial agriculture is just as essential to supporting a stable biological system as plant diversity on non-commercial landscapes. Furthermore, less diverse crop areas lead to higher, more intensive pesticide use, indicating a threat to environmental and human health, as well as food security. This research highlights the need to develop policies that facilitate a decrease in overall pesticide use by helping farmers and global leaders make more knowledgeable decisions about crop area size and diversity to sustain biodiversity. Researchers note, “While [crop] complexity increases stability and reduces high deviations in insecticide use, accounting for crop and farmer-specific characteristics is crucial for statistical inference and sound scientific understanding. In this study, researchers aim to understand how crop and landscape diversity impacts pest populations, using insecticide use data as a surrogate for pest populations data. Data observations are from Kern County Agricultural Commissioner (CAC), California, over the period 2005 to 2017. Crop data includes crop type, acceptable field size, field and farmer permit number, and active dates for the field. To estimate pesticide use variance, researchers summated annually and peak insecticide […]

(Beyond Pesticides, November 10, 2020) Higher rates of plant diversity can limit pest pressure and reduce the need for pesticide use, finds a new study published by the German Centre for Integrative Biodiversity Research. With rampant declines in insect biodiversity from the ongoing insect apocalypse, it is critical that farmers and ecologists better understand the natural interplay between plants and insects, and the important ecosystem services that flow from these interactions. “Our experiments show that conserving plant diversity provides multiple benefits for controlling herbivore pests, which could play a key role in reducing inputs of agrochemicals and enhancing plant productivity,” said study coauthor Andrew Barnes, PhD. Scientists investigated the importance of plant biodiversity through study of two ongoing biodiversity experiments. One known as the The Jena Experiment, based in Central Europe, and another, the Cedar Creek Biodiversity Experiment, in the state of Minnesota. Both sites established blocks of plant diversity gradients, flowing from monoculture plots to those with 16 species or more. Researchers aimed to investigate how insect food webs and feeding behavior, plant biomass, and pest predator response changes as a function of plant biodiversity. Results showed that higher plant diversity resulted in an insect (herbivore pest) feeding rate […]

(Beyond Pesticides, October 29, 2020) Natural areas around farmlands play an important role in managing pest outbreaks and therefore reducing insecticide use, a new study published in the journal Ecology Letters finds. While industrial agriculture puts pressure on farmers to grow single crops on ever larger farms to achieve economies of scale, these monoculture landscapes have significant downsides for public health and the environment. “Overall, our results suggest that simplified landscapes increase vineyard pest outbreaks and escalate insecticide spray frequencies,” said lead author Daniel Paredes, PhD, to the Daily Democrat. “In contrast, vineyards surrounded by more productive habitats and more shrubland area are less likely to apply insecticides.” To investigate the effect of nearby landscapes on farm pest pressure, the team of University of California, Davis scientists used a database created by the government of Spain. For 13 years, the government monitored 400 Spanish vineyards for the presence of the European Grapevine Moth. The moth is a notorious vineyard pest (discovered in California vineyards in 2009), laying three generations of eggs on grapes. In the first generation, the moth larvae will web and feed on flowers. In the second and third, they feed on berries, damaging harvests. Scientists developed a […]

(Beyond Pesticides, October 1, 2020) A federal judge on September 24, 2020 dismissed an  environmental lawsuit seeking to reinstate a U.S. Fish and Wildlife Service (FWS) rule, killed by the Trump Administration, which banned the use of neonicotinoid insecticides, genetically engineered (GE) crops, and adopted a precautionary approach to pest management. The decision comes on the heels of a Center for Biological Diversity (CBD) analysis that reports a 34% increase in the pesticide use on U.S. national wildlife refuge acres over a two year period from 2016-2018. This analysis is an update to CBD’s 2018 report, No Refuge, which is the first of its kind to offer comprehensive details of agricultural pesticide spraying in national wildlife refuges. Wildlife refuges act as a sanctuary, providing habitat and protection essential for the survival and recovery of species nationwide. However, pesticide spraying in or around wildlife refuges threatens the survivability and recovery of species that reside there as many of these pesticides are highly toxic to human and animal health. Analyses like these are significant, especially since the globe is currently going through the Holocene Extinction, Earth’s 6th mass extinction, with one million species of plants and animals at risk of extinction. In 2012, […]

(Beyond Pesticides, September 17, 2020) The apparel industry becomes the latest contributor to global biodiversity loss, directly linking soil degradation, natural ecosystems destruction, and environmental pollution with apparel supply chains, according to the report, “Biodiversity: The next frontier in sustainable fashion,” by McKinsey & Company. Although there are many studies on the fashion industry’s impact on climate change, much less research discusses the impact the industry has on biodiversity. The globe is currently going through the Holocene Extinction, Earth’s 6th mass extinction, with one million species of plants and animals at risk of extinction. With the increasing rate of biodiversity loss, advocates say it is essential for government agencies to hold the fashion industry accountable for the direct (i.e., excessive agrochemical use, water consumption) and indirect (i.e., water pollution from run-off) impacts on the environment, not only to protect the well-being of animals, but humans, as well. Researchers in the study note, “We expect biodiversity to become an even greater concern for consumers and investors in the coming years. Covid-19, instead of slowing the trend, has accelerated it—perhaps because people now understand more deeply that human and animal ecosystems are interdependent. It’s time for the apparel industry, which to date has contributed heavily […]

(Beyond Pesticides, July 16, 2020) Long-term exposure to sublethal (low-level) concentrations of the neonicotinoid in soil negatively affects the health and behavioral development of black garden ants (Lasius niger) colonies, according to a study published in Communications Biology by scientists at the University of Bern, Switzerland. Ants are one of the most biologically significant insects in the soil ecosystem, acting as ecosystem engineers. Their burrowing behavior aerates the soil, allowing oxygen and water to penetrate down to plant roots. Additionally, ants increase soil nutrient levels by importing and accumulating organic material like food and feces, thus enhancing nutrient cycling. Like many other insects, ants are unfortunate victims of the global insect apocalypse or population decline, and much research attributes the recent decline to several, including pesticide exposure. Broad-spectrum pesticides, like neonicotinoids, indiscriminately kill pests and nontarget organisms alike, as their ubiquitous use contaminates soils, even in untreated areas. This study highlights the necessity of rethinking chemical pest management, developing sustainable agricultural practices that reduce the use of agrochemicals, like pesticides, to prevent permanent environmental ecosystem damage. Researchers in the study note, “To prevent irreparable damages to functioning ecosystems, [we] suggest to either fully incorporate long-term effects in risk assessment schemes, or to make a shift […]

(Beyond Pesticides, May 26, 2020) Across the pond, the European Commission (EC) has announced plans to protect biodiversity and build a more sustainable food system, and identified the reduction of pesticide use  and the expansion of organic agriculture as pillars of the scheme. The EC expects that the initiative, which will require EU member states’ endorsement, will advance progress on the EU goal of eliminating greenhouse gas emissions by 2050, given that 10% of emissions arise from the agricultural sector. The EC’s goals are important and laudable, but Beyond Pesticides is clear: reduction of pesticide use in service of them is not an adequate strategy to ensure long-term success. Genuine success requires the elimination of the use of synthetic chemical pesticides, fertilizers, and other toxic inputs, and the transition to agricultural and land management systems that work with nature, rather than fight against it. Regenerative, organic practices are the path to a livable future, according to Beyond Pesticides. The EC, which is the executive branch of the EU, expects its plan to reduce use of pesticides by 50% by 2030; reduce use of antimicrobial chemicals, including antibiotics, in fish and animal farming by 50%; dedicate a minimum of 25% of arable […]

(Beyond Pesticides, May 18, 2020) On May 15, 2020, Beyond Pesticides sued Exxon Mobil Corporation (Exxon) for “false and deceptive marketing,” misrepresenting to consumers that it “has invested significantly in the production and use of “clean” energy and environmentally beneficial technology.” The truth, according to the complaint (Beyond Pesticides v. Exxon Mobil Corporation) filed in DC Superior Court, is that the vast majority of Exxon’s business continues to be in the production and use of petroleum, natural gas, and petrochemicals, including pesticides. These activities are significant contributors to the climate crisis and the decline of pollinators and biodiversity, threatening the viability of biological systems that sustain life, according to Beyond Pesticides. “ExxonMobil’s advertising and marketing mislead the public by presenting ExxonMobil’s clean energy activities as a significant proportion of its overall business,” according the lawsuit. In an age where consumers are looking to support responsible companies that are supporting and transitioning away from fossil fuel-based energy and chemical products, “ExxonMobil is able to capture the growing market of consumers,” according to the complaint. Surveys have found that consumers are more likely to buy products and services based on corporate image. For example, a 2015 Nielsen survey finds that the majority […]

(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 […]

(Beyond Pesticides, April 28, 2020) Roughly a quarter of the global insect population has been wiped out since 1990, according to new research published in the journal Science. Billed as one of the most comprehensive assessments to date, the study finds significant overall insect declines, but notes of some specific bright spots. While variation in the ongoing crisis is to be expected, ultimately the trends in the data show the need for immediate policy and regulatory action to protect the insect world as the foundation of global food webs. The team of European scientists behind the research analyzed 166 studies spread out over 41 countries, and consisting of over 1,600 sites, with data beginning in the mid-1920s. Overall trends found declines in terrestrial insect biomass to be nearly 1% each year (~9% each decade). However, contrasting this data was a bright spot – freshwater insects were found to be increasing at an annual rate just over 1% (~11% each decade). The authors caution, however, that because fresh water covers only 2.4% of the earth’s surface, the increase may not be a good spatial representative of broader trends. While North America appeared to show more significant declines when compared to Europe, […]

(Beyond Pesticides, March 17, 2020) The number of monarch butterflies overwintering in Mexico is down 53% from last year, according to a count conducted by World Wildlife Fund (WWF) Mexico. While WWF indicates the decline was expected due to unfavorable weather conditions during the species southward migration, other environmental groups are raising red flags. “Scientists were expecting the count to be down slightly, but this level of decrease is heartbreaking,” said Tierra Curry, a senior scientist at the Center for Biological Diversity. “Monarchs unite us, and more protections are clearly needed for these migratory wonders and their habitat.” WWF’s count found that monarchs occupied seven acres this winter, down from 15 acres last year. Reports indicate that 15 acres is a minimum threshold needed to prevent a collapse of the butterfly’s migration and possible extinction. This was the goal stated by the 2015 White House Pollinator Task Force, which the current administration is failing to see through. While weather conditions play an important role in monarch migration from the U.S. and Canada south to Mexico, the species is under threat from a range of environmental factors. Monarchs depend on milkweed plants to lay eggs, and monarch caterpillars feed solely on […]

(Beyond Pesticides, March 9, 2020) It’s time to think about gardening! Whether you’re growing vegetables to eat or flowers for pollinators, you’ll want to be sure that your seeds and plants are free from harmful pesticides. Seeds and plants in many garden centers across the country are grown from seeds coated with toxic fungicides and bee-harming neonicotinoid pesticides, or drenched with them. Plant organic seeds and plants! As bees suffer serious declines in their populations, we urge people and communities to plant habitat that supports pollinator populations, and have provided information to facilitate this in our BEE Protective Habitat Guide. However, plants are too often grown with hazardous pesticides that either harm pollinators in their cultivation or threaten bees as they pollinate or forage on treated plants. For more information on the dangers of neonicotinoid coated seeds, see Beyond Pesticides’ short video Seeds That Poison. Beyond Pesticides has compiled a directory of companies and organizations that sell organic seeds and plants to the general public. Included in this directory are seeds for vegetables, flowers, and herbs, as well as living plants and seedlings. Specific questions on each seller’s seeds can be directed to their customer service line. You can also download a handy bi-fold brochure version of this […]

(Beyond Pesticides, March 6, 2020) Scientists from Imperial College London have just published their recent research on impacts of pesticides on larval bumblebees exposed through neonicotinoid-contaminated food sources. Many studies have looked at the devastating impacts of pesticides on adult insects, including pollinators — and bees, in particular. This research, however, examines how exposure to the neonicotinoid imidacloprid, through consumption of contaminated nectar and pollen during the larval stage, affects bumblebees (Bombus terrestris audax). It finds that these exposures cause abnormal brain growth in some parts of the bees’ brains, and significantly impairs learning ability compared to bees who were not exposed. Advocates maintain that neonicotinoid pesticides should be banned for their widespread and severe damage to insects and the environment broadly, in addition to human health concerns. Neonicotinoids (neonics) comprise a class of pesticide used intensively in many parts of the world. They may be applied to plant foliage, or directly to soils as a drench, but the predominant use is for seed treatment. These pesticides are banned or restricted in some places, including in the European Union, France, Germany, and Italy; some states have also worked to rein in their use. Previous research out of Harvard University has […]

Experimental ponds in Gault Nature Reserve. Photo credit: Vincent Fugère (Beyond Pesticides, March 5, 2020) A new study conducted by researchers at McGill University investigated phytoplankton (microscopic algae) response and resilience to Roundup exposure. “Community rescue in experimental phytoplankton communities facing severe herbicide pollution” was published in Nature Ecology & Evolution. Researchers found that algae can develop resistance to contamination, but surviving phytoplankton communities are much less diverse. Diversity loss is cause for concern as it could hinder adaptation to other potential stressors, such as climate change.  Using experimental ponds, researchers first exposed some phytoplankton communities to low levels of Roundup over time, then dosed the ponds with a lethal amount.  Groups that had been given low doses survived the lethal phase whereas unpolluted, control ponds did not. Researchers observed “community rescue,” where genetic changes avert population collapse in a lethal environment. In fact, glyphosate eventually became a fertilizer in resistant ponds as it is a significant source of phosphorus. Other studies, too, have noted that phosphorous loading is an overlooked impact of glyphosate contamination. Phytoplankton matter because their disruption can cause a trophic cascade and impact other organisms. “These tiny species at the bottom of the food chain play […]

(Beyond Pesticides, February 21, 2020) Last week in Minnesota, state Representative Jean Wagenius introduced measure H.F. 1255 that would give cities the opportunity to ban local use of bee-lethal pesticides. This is the latest in a series of attempts to fight state pesticide preemption, an industry-promoted law that prevents localities from restricting pesticide use more stringently than the state. In the face of inaction at the federal and state levels, advocates and legislators in Minnesota are attempting to regain local control to help save their declining, Midwestern pollinators. Representative Wagenius says about the measure, “Minnesotans should be able to protect pollinators if they want to. We value local control in this state, and we always have.” H.F. 1255 will allow cities to opt into a blanket ban of pesticides determined by the Environmental Protection Agency (EPA) to be hazardous to bees. Pesticides with an EPA bee-advisory box are listed on the state’s Department of Agriculture website and referred to as “bee-lethal” by Minnesota legislators. Patrick Hanlon, director of environmental programs for the city of Minneapolis, says cities would work with Department of Agriculture, businesses, and residents that might be impacted by these restrictions before enacting the bill. Local advocates have […]

(Beyond Pesticides, February 19, 2020) The ongoing insect apocalypse isn’t sparing the iconic firefly. In an article published this month, “A Global Perspective on Firefly Extinction Threats,” experts are sounding the alarm over declines in fireflies attributed to habitat loss, light pollution, and indiscriminate pesticide use. “Our goal is to make this knowledge available for land managers, policy makers and firefly fans everywhere,” said study co-author Sonny Wong, PhD, of the Malaysian Nature Society to USA Today. “We want to keep fireflies lighting up our nights for a long, long time.” Although there is scant monitoring data on firefly populations, studies that have been conducted over the last decade, alongside anecdotal reports and expert opinion, have led to international concern. To assess conservation status and threats to firefly species, the International Union for the Conservation of Nature (IUCN) established a Firefly Specialist Group. The study, part of the specialist group’s investigation, surveyed firefly experts from around the world on what they viewed as the primary threats to firefly populations. Experts specified habitat loss, light pollution, and pesticide use as the three top concerns, though water pollution, tourism, invasive species, and climate change were also discussed as minor contributing factors. Night-time […]

(Beyond Pesticides, February 3, 2020) In more bad news from the insect world, recent research published in the Proceedings of the National Academy of Sciences reveals a precipitous decline in numbers of mayflies where they have been historically abundant. The research finds that in the Northern Mississippi River Basin, seasonal emergence of burrowing mayfly (genus Hexagenia) adults declined by 52% from 2012 to 2019; in the Western Lake Erie Basin, from 2015 to 2019, the reduction was a shocking 84%. Neonicotinoid insecticides are a significant factor in this decline because mayflies are extremely vulnerable to their impacts, even at very low exposure levels. Ask Congress to tell EPA, USDA, and the Department of Interior to develop a joint effort to ensure that its decisions and compliance with its authorizing statutes address the crisis of the threat to mayflies. Ephemeroptera to entomologists—“mayflies” to the rest of us—is an insect order comprising keystone species, on which other species in an ecosystem are very dependent, and without which, the ecosystem would undergo drastic change. The plummeting mayfly “count” is especially alarming because mayflies are a critical, primary food source in aquatic and terrestrial ecosystems, and provide an important ecological service. As the research study notes, “Seasonal animal movement […]

Photo: Beyond Pesticides’ board member Chip Osborne and student advocate Bridget Gustafson meet on a University of California organic land management pilot site, supported by Beyond Pesticides. (Beyond Pesticides, January 23, 2020) University of California (UC) President Janet Napolitano recently has approved recommendations made by the UC Herbicide Task Force, a proposal that falls short of systems change that student activists are advocating. New changes will, however, restrict the use of some toxic pesticides and increase transparency across the university’s ten campuses. While the decision represents an important step forward, advocates remain critical of integrated pest management (IPM) policy and support an overall transition to organic land management. The UC Board of Regents will meet today to discuss the decision. President Napolitano will continue the suspension of glyphosate, established last year, until a UC-wide integrated pest management (IPM) policy is implemented and all ten UC campus locations complete individual IPM plans. A system-wide “oversight committee” will guide and authorize school IPM committees. The overarching IPM policy will restrict application of highly toxic pesticides, only permitting use after a local IPM committee has reviewed and approved its specific use application following an IPM-based assessment. Other synthetic pesticides will be subject to […]

(Beyond Pesticides, December 23, 2019) An unintended consequence of the National Organic Standards, the rules that govern certified organic agricultural production, actually provides an incentive for the conversion of critical ecosystems to organic cropland, fueling deforestation and biodiversity loss. Tell the National Organic Program to issue regulations that will prevent the conversion of native ecosystems to organic cropland. One National Organic Program (NOP) requirement for organic certification—a three-year waiting period during which land must be free of disallowed substances—encourages the conversion of critical ecosystems, which do not require the three-year waiting period. Conversions of native landscapes to working organic land to date include losses of: a California forest, Colorado prairies, a New Mexico wetland, and native sagebrush lands in Washington and Oregon. The Wild Farm Alliance, which provides critical leadership on the issue, points out, “These areas, that were once delivering critical ecosystem services and providing essential habitat for wildlife, are no longer performing the same functions and [it] would take hundreds of years to reverse the damage.” The National Organic Standards Board (NOSB), which is responsible for advising the U.S. Department of Agriculture (USDA) on implementation of the Organic Foods Production Act (OFPA), has been studying this problem since 2009, ultimately resulting […]

(Beyond Pesticides, November 7, 2018) A former employee of the Minneapolis Park and Recreation Board claims that other staff members misused and disposed of pesticides in protected areas next to Lake Harriet. The controversy comes at a pivotal moment for Minneapolis, as Minneapolis Public School District and the Park and Recreation Board are beginning a demonstration organic land management project on a number of properties. Advocates are pushing for organic land management as an alternative to chemical-intensive practices. Minneapolis gardener Angee Ohmah Siegal says she was at the Lyndale Park Peace Garden when she saw parks staff spraying herbicides on a windy day. According to Russ Henry, a local advocate who she told her story to, Siegal had to head to the hospital due to “uncontrollable vomiting.” What more, Siegal claims that the same employees would dump unused or leftover pesticides into a pond beside the Roberts Bird Sanctuary. Mr. Henry and Ms. Siegal issued their complaint with Park Board commissioners on October 2, carrying a large poster of a mutated frog with six legs that Ms. Siegal says she had photographed near the area. Commissioners are investigating further into the allegations but say they need more specific evidence. Volunteers […]

(Beyond Pesticides, September 27, 2019) The U.S. Fish and Wildlife Service (USFWS) will be required to protect the habitat of the endangered rusty patched bumblebee, per a settlement with the Natural Resources Defense Council (NRDC) reached earlier this week. The bee was listed under the Endangered Species Act (ESA) in 2017, but USFWS has yet to designate the “critical habitat” for the bee where improved protections must be made to ensure its recovery. With the decline of both wild and managed pollinators throughout the U.S., action on this issue by federal agencies is sorely needed. According to NRDC, the settlement will require FWS to propose critical habitat by July 31, 2020, unless it makes a finding that habitat protections are not prudent. The Service must then finalize any habitat protections by July 31, 2021. Under ESA, FWS is required to designate the critical habitat of a listed species within one year of its listing if not included within its listing announcement. Thus, by drawing out this process, FWS is flouting this important action that will lead to real on-the-ground protections. “The U.S. Fish and Wildlife Service has violated federal law—again—by not designating critical habitat for the rusty patched bumble bee,” […]

(Beyond Pesticides, September 24, 2019) “Over increasingly large areas of the United States, spring now comes unheralded by the return of the birds, and the early mornings are strangely silent where once they were filled with the beauty of bird song,” Rachel Carson wrote in Silent Spring in 1962. New research finds that quote has held true since it was written. Over three billion birds, or 29% of 1970s abundance have been lost in North America over the last 50 years. To make these dismal determinations, scientists drew from multiple long-term bird monitoring datasets, and a network of nearly 150 weather radars that pick up and thus have recorded the trajectory of migratory birds. Long-term surveys helped scientists determine the 3 billion bird decline, while satellite data found that migratory bird abundance has declined by 9.1% since 2007. In general, 57% of bird species are in decline, with showing the largest loss. Ninety percent of all declines were within 12 bird families: American sparrows, warblers, blackbirds, larks, Old world sparrows, swallows, nightjars, swifts, finches, flycatchers, starlings, and thrushes. Only waterfowl and wetland bird species showed any increase, 13% and 56%, respectively. Ducks, geese, and raptors all improved population levels more […]
