(Beyond Pesticides, February 13, 2026) In a novel, continent-wide study of soil biodiversity throughout Europe published in Nature, researchers find 70% of the sampled sites contain pesticide residues, which “emerged as the second strongest driver of soil biodiversity patterns after soil properties,†particularly in croplands. As soil biodiversity is key for ecosystem functioning, agricultural and land management practices that safeguard biodiversity are imperative. This study, however, highlights how pesticides alter microbial functions, including phosphorus and nitrogen cycling, and suppress beneficial taxa, such as arbuscular mycorrhizal fungi and bacterivore nematodes, and adds to a wide body of science that links pesticide residues in soil to adverse effects on biodiversity. In analyzing 373 sites across woodlands, grasslands, and croplands in 26 European countries, and examining the effects of 63 pesticides on soil archaea, bacteria, fungi, protists, nematodes, arthropods, and key functional gene groups, the data reveals “organism- and function-specific patterns, emphasizing complex and widespread non-target effects on soil biodiversity.†As the authors state, “[T]o our knowledge, ours is the first study to demonstrate the relative importance of pesticides in comparison to soil properties, ecosystem type and climate at a continental scale.†Study Importance As Kristin Ohlson describes in her book The Soil […]

(Beyond Pesticides, February 10, 2026) Species that are integral to pest management allow for crucial ecosystem services that negate the need for pesticides in agricultural or land management practices. In a study published in Agriculture, Ecosystems & Environment, researchers from France find pesticide-free fields promote carabid beetles and spiders, generalist arthropod predators that consume slugs, aphids, and mites, that in turn support healthy, organic systems. The study findings highlight the importance of utilizing farming practices that promote biodiversity and foster natural enemy populations as a pest management strategy.  “In this study, we assessed the assemblages of emerging and circulating ground-dwelling carabids and spiders during four months in a continuous mosaic of pesticide-free winter-sown crops under contrasted tillage regimes (minimum vs. conventional tillage) and sown flower strips bordering fields,†the authors describe. They continue: “We detected clear patterns, with high in-field carabid and spider overwintering densities than in adjacent flower strips… Our results also demonstrate the key role of pesticide-free fields under minimum tillage, acting both as a high-quality overwintering site for some dominant carabid species and as a source habitat, as several predator species activity-density responded positively to the increased area of minimum tillage fields in the surroundings.†Background […]

(Beyond Pesticides, February 9, 2026) Every year during the lead-up to Valentine’s Day, the story of pesticide-intensive practices in the flower industry is told. The hazards of pesticides used in flower production and their resulting residues are well-documented. At the same time, the benefits of flowers to one’s psychological well-being have been studied, with findings that suggest flowers are a positive stimulus for emotional well-being, beyond the beauty that they bring to a home, wedding, office, or hospital room. One scientific study shows that flowers perform a socio-emotional function, while a survey done by the American Society for Horticultural Science finds that, “Consumers consistently reported positive effects of cut flowers on mood, morale, and stress reduction.†People want to share this positivity through the giving of flowers, especially on Valentine’s Day. Despite these benefits, the few studies that have been conducted show elevated pesticide exposure for florists through inhalation and dermal absorption. Beyond Pesticides’ network, recognizing that flowers can be grown with organic practices, is asking EPA and Congress to eliminate pesticide use in flower production and resulting residues, while supporting the transition to organic management practices. Similar to food production, the organization says that health and the environment do not […]

(Beyond Pesticides, February 3, 2026) In analyzing the direct and indirect effects of pesticides that act simultaneously upon macrozoobenthos communities (invertebrates living in or on sediment) in standing small water bodies (SWBs) in Germany, researchers find high risks to biodiversity and ecosystem functioning. Published in Hydrobiologia, the experiment finds high risks to invertebrates and highlights how both direct and indirect effects are vital to comprehensive assessments of pesticides. While typically overlooked in regulatory reviews, SWBs are defined as shallow standing or running freshwaters “with a surface area of less than 50 hectares (ha),†such as lakes or ponds, including farm ponds, as well as headwater streams, springs and flushes, and ditches. SWBs are biodiversity hotspots that contribute to numerous ecosystem services and are adversely affected by agricultural land use effects such as pesticide contamination. “Holistic assessments of pesticide effects on invertebrate communities in standing small water bodies have, however, not yet been successful,†the authors note. To address this, the researchers developed an indicator for evaluating pesticide impacts on macrozoobenthos communities, populated with aquatic invertebrates, such as snails, worms, crayfish, and clams, through indirect toxic effects on aquatic plants called INPOND: INdirect Pesticide impacts ON Diversity in standing small water […]

(Beyond Pesticides, February 2 2025) With the Trump administration withdrawing from international organizations that historically advance a shared world view of global sustainability (from health and the environment, to peace and justice), people are calling on the U.S. Congress and state governors to support critical health and environmental programs that link humanity across the globe. Beyond Pesticides is collaborating on an action to: Tell Congress to support and fund international organizations critical to the global health of humans and the biosphere, AND Tell Governors/Lieutenant Governors to join (as well as thank them for joining) the Governors Public Health Alliance and to expand their support for international agencies that protect biodiversity and mitigate the climate crisis (IUCN, IPBES, and IPCC).  Will the U.S. Congress and state government step up to link across national borders when the Trump administration steps back from worldwide existential health and environmental crises? Among the 66 organizations affected by this action are the World Health Organization (WHO), the International Union for Conservation of Nature (IUCN), the Intergovernmental Science Policy Platform on Biodiversity and Ecosystem Services (IPBES), and the Intergovernmental Panel on Climate Change (IPCC). These organizations all support global health, and withdrawing from them is “contrary to the interests of the United […]

(Beyond Pesticides, January 30, 2026) In a 2025 study published by the British Ecological Society’s Animal Ecology, researchers’ findings “suggest that beaver engineering created structurally diverse habitats that supported a broader range of bat species.†It is well-established that bats perform important ecosystem services, which help to prevent and manage insect problems in balanced ecosystems. The researchers find: “By modifying both habitat structure and prey abundance, beaver engineering affected bat activity, richness, and feeding activity directly and indirectly. These changes operated across aquatic–terrestrial boundaries, highlighting the cross-ecosystem influence and ecological complexity of ecosystem engineering.†Environmental and public health advocates have long called for nature-based solutions to pest management that provide critical support to at-risk wildlife (like beavers and bats) and reduce costs for agrichemical inputs to farmers due to improved ecosystem services (such as pest suppression and management). In turn, this holistic approach leads to secondary benefits like improved climate resilience and public health protection that are associated with the elimination of petrochemical pesticide use. Background and Methodology The researchers focused their study in eight stream ecosystems in differing contexts across Switzerland, choosing a diversity of habitats, including urban, agricultural, and forested zones. An area was selected with an active […]

(Beyond Pesticides, January 29, 2026) A study of ecotoxicity risk from neonicotinoid insecticides, published in Environmental Chemistry and Ecotoxicology, finds that chemicals in this class of pesticides, particularly dinotefuron, increase the body temperature of Apis mellifera (European honey bee) and subsequently accelerate the translocation (movement) of contaminants into hives by the honey bees. The research indicates that neonicotinoids affect acetylcholine receptors in the nervous system, leading to an “elevation in octopamine titer [neurotransmitter/hormone] and subsequent increase in the body temperature of honeybees,†the authors report. They continue: “Furthermore, we observed a considerable upregulation [of] the expression of a flight gene flightin in honeybees. This gene accelerates the homing behavior of honeybees and facilitates the rapid and frequent transport of neonicotinoid pesticide-contaminated nectar to the hive.†In describing their results, the researchers state: “For the first time, we propose that neonicotinoid pesticides accelerate the homing ability of honeybees by affecting their body temperature, which leads to more neonicotinoid pesticides entering the hive and explains the prevalence of neonicotinoids and at higher concentrations in terms of their effects on the honeybee body temperature that enhances homing.†This accelerated movement of neonicotinoid pesticides into honey bee hives heightens the toxicity risks to honey […]

(Beyond Pesticides, January 15, 2026) “Birds and bats consumed over 87 rice pest species in West African lowland rice fields,†according to a recent study published in Agriculture, Ecosystems & Environment. The authors continue, “Our findings highlight the importance of maintaining and managing a diverse community of bats and birds for network resilience.†In this context, the research distinguishes the “predator-prey†as established through the ecological balance of diverse organisms in nature from a “predator-pest†orientation that views some organisms as unwanted and targets for control and more subject to human manipulation.  The authors describe the predator-pest network as a means to quantify the “ecosystem services†impact, with the researchers noting that they “investigated the role of predator and prey species in the predator–prey network and compared those roles with that of the predator–pest network, to further explore their potential as pest suppressors.†Communities across the United States and globally are looking for opportunities to transition to alternative pest management strategies given decades-long increasing reliance on synthetic pesticides and fertilizers, which contribute significantly to looming existential crises of biodiversity collapse, public health decline, and planetary instability of ecosystems, climate, and geopolitics. As evidenced in a recent report by Farm Action […]

(Beyond Pesticides, January 2, 2026) Texas-based pecan orchard Swift River Pecans is collaborating with local conservation nonprofit Merlin Tuttle’s Bat Conservation “so they could collect more information on the species that visit his 266-acre property, and to show off the bats’ value to his operation,†according to recent coverage by NPR affiliate KCUR. “Bats love to munch on insects like stink bugs and moths. Some farmers are now relying on the mammals for pest control – and ditching chemicals,†says Michael Marks, reporter for NPR (Harvest Public Media) and Texas Standard. The orchard operator and nonprofit have been collaborating since 2004, after Troy Swift (orchard owner) employed a chemical-intensive approach since purchasing the land in 1988. Merlin Tuttle, “an ecologist and conservationist who has spent 65 years studying bats around the globe,†has been setting up bat boxes using cypress trees from a lumber mill on-site—the researcher has opted for this wood type because it is porous and regulates temperature appropriately. “Our job is to work with Mother Nature instead of against her to make the best pecans money can buy. That’s the way we see it,†says Mr. Swift, who also serves as the president of the Texas Pecan […]

(Beyond Pesticides, December 16, 2025) Through a literature review and data analysis of almost 2,000 soil samples, the authors of a recent study find negative effects on the presence of plant-beneficial bacteria (PBB) in soil with pesticide exposure, particularly bacteria with plant growth-promoting traits that are essential for crop productivity. The study, published in Nature Communications, by researchers at China’s Shaoxing University and Zhejiang University of Technology, adds to scientific literature documenting the effects of pesticides on soil health. “Pesticides not only reduce PBB diversity as individual factors, but they also exert synergistic negative effects with other anthropogenic factors… further accelerating the decline in PBB diversity,†the researchers state. They continue, “Increased pesticide risk also leads to a loss of functional gene diversity in PBB about carbon and nitrogen cycling within essential nutrient cycles, and a reduction in specific amino acid and vitamin synthesis.†In elucidating these impacts, this study reinforces previous research that connects pesticide use with deteriorating soil health, further stressing the urgent need for adopting a systems-wide transition to organic agricultural and land management practices. Soil Microbiome Health As the authors discuss, plant–soil–microbe interactions play a critical role in the growth, development, and overall health of plants, […]

(Beyond Pesticides, December 5, 2025) A study published this month in Environmental Pollution analyzes the role of neonicotinoid insecticide exposure on bird populations, finding a significant negative effect of imidacloprid use on insectivorous bird abundance. In comparing the effects of the insecticide imidacloprid on bird abundance in France before and after the 2018 ban, the researchers show a weak recovery of bird populations after 2018. The persistent nature of imidacloprid, however, as well as the continued use of other petrochemical pesticides that have adverse effects on bird species, continues to impact populations of all types of birds and other wildlife, leading to cascading impacts on biodiversity.   “Our study shows that imidacloprid is a major covariate of the abundance of birds, in addition to other pesticides that are also negatively related to bird populations, and that these effects are not uniform across species,†the authors report. They continue in saying that the relationship between neonicotinoids and bird abundance varied across bird diets, as “the abundance of insectivorous birds was consistently lower under increasing pesticide use, in particular imidacloprid.†Background As shared in the study and on Beyond Pesticides’ Birds page, bird species can be exposed to pesticides directly through ingestion […]

(Beyond Pesticides, November 24, 2025) In his article on ecological traps, Professor Danilo Russo, PhD, explains the harm caused to wildlife from well-intentioned efforts to establish habitat on chemical-intensive farms or areas otherwise subject to chemical exposure. Dr. Russo et al., in “To improve or not to improve? The dilemma of “bat-friendly†farmland potentially becoming an ecological trap†(2024), write, “[W]hen restoring habitats for bats in conventional farmland, potential unintended outcomes must be considered, particularly if restoration actions are not accompanied by mitigation of key threats. These threats include the persistent and widespread use of pesticides. . .†(See also a study in Environmental Entomology, which shows that habitat and open space near agricultural fields become a killing field of pesticides, threatening biodiversity due to contamination from toxic drift.) As this false sense of protection persists, Beyond Pesticides is calling on governors to adopt policies that support organic land management and ecological balance. Organic practices are, by definition, a systems change that is aligned with nature and the biodiversity protection that is needed. Ecological traps are incremental steps that fail to address underlying systemic problems that allow hazards to persist. While they represent an affirmative action in an attempt to adopt restorative measures, the […]

(Beyond Pesticides, November 20, 2025) Recent scientific literature finds heightened toxicity associated with pesticide metabolites, the transformation/breakdown products of the parent compounds, that threaten the health of the soil, wildlife, and humans. This research stresses the importance of the U.S. Environmental Protection Agency (EPA) evaluating metabolites, which is currently insufficiently included in regulatory processes. In a literature review in Global Change Biology, the researchers point out multiple areas in which regulations fail to address key criteria, including metabolites, saying: “Pesticide risk assessments currently rely on surrogate species and focus primarily on acute lethality metrics, failing to capture the broader impacts on non-target organisms and thus biodiversity. Under the directives of regulatory agencies worldwide, this traditional approach overlooks the complex interactions between multiple stressors, including climate change, land-use shifts, and pesticide transformation products. Pesticide risk assessments must therefore undergo a paradigm shift to account for these complex interactions, which disproportionately affect insect pollinators, other non-target species, and biodiversity at large.†A metabolite is a breakdown product that forms when a pesticide is used in the environment and mixes with air, water, soil, or living organisms. All metabolites fall under the category of transformation products, which is the broader term for any […]

Dr. Russo’s chapter, entitled “Impact of Climate Change on Bats Involved in Biological Control,†explains one of the lost benefits of ecological balance attributable to the climate crisis. As explained in the book: “In conservation biological control, habitats surrounding and within crops are managed to favour an increase in natural enemy populations while suppressing pest populations. These agroecological systems can be complex, and are affected by climate change.†The ability of climate change to influence the effectiveness of biological control systems is explored, showing the “effects on the large diversity of macro- and microorganisms involved in biocontrol, and the possible increase or decrease in pest outbreaks following changes in characteristics (morphology, physiology, behaviour….), distribution or phenology.†Dr. Russo is a full professor of ecology at the University of Naples Federico II, an international leader in bat research, and coauthor of A Natural History […]

(Beyond Pesticides, November 18, 2025) A study published in Horticultural Plant Journal provides additional evidence on the viability of organically managed farmland based on tomatoes cultivated through traditional plant breeding and regional variances. The authors of the research find that, “Despite the positive trend of the organic sector’s development in Europe, the number of tomato varieties bred for organic farming is still limited since efforts have been mainly focused on high input conditions.†They continue: “As a result, the existing cultivars may not suit to organic production [ ] as cultivars chosen for conventional [chemical-intensive] systems often respond well to chemical fertilizers to improve crop output, but they might not maximize nutrient uptake in organic systems where minor external inputs are provided.†In this context, the marketplace is not maximizing the potential productivity of organic systems due to the limited availability of seeds and plant material best suited to conditions in sync with local ecosystems. The designed methodology, as well as the findings, show that there are opportunities for public investment to support systems that cultivate agricultural products without reliance on petrochemical-based fertilizers, pesticides, and seeds treated with pesticide products and other genetically modified characteristics. For millennia, humans have worked […]

(Beyond Pesticides, November 17, 2025) Beyond Pesticides ramped up its campaign to transition parks, playing fields, and schoolyards to organic land management after the release of a study showing synergistic effects of glyphosate (Roundup) and urea fertilizers on earthworms and soil health. The organization’s network is asking Mayors nationwide to lead the transition, pointing to the inadequacy of the current system of regulating pesticides based on risk assessments of individual chemicals or individual chemical families. Chemicals interact, causing increased impacts on human, ecological health, and biodiversity. Moreover, humans, other species, and the biosphere rarely experience exposure to single chemicals or chemical families; exposure to multiple chemicals is the rule, not the exception.  Synergistic effects associated with the use of the weedkiller glyphosate have been implicated in several studies showing magnified adverse impact in soil organisms and in mixture with other chemicals: The extensive use of glyphosate is linked to effects on nontarget soil organisms, with the risks to soil ecosystems widely studied. (See here, here, here, here, and here.)  One study shows that frequent application in tropical systems of glyphosate “reduced soil macroarthropod richness by 21% and altered community composition.  “A recent global risk assessment of glyphosate further estimated that 67−93% of soils pose high risks to Collembola [springtails] and 43−67% pose medium to high risks to […]

(Beyond Pesticides, November 4, 2025) A study of earthworms published in Environmental Science & Technology highlights how chemical mixtures can have both synergistic and species-specific effects, threatening the soil microbiome and overall soil health. In exposing two species, Eisenia fetida and Metaphire guillelmi, to the weed killer glyphosate alone and in combination with urea, a form of synthetic nitrogen fertilizer, the researchers find enhanced toxicity with co-exposure as well as varying health effects between the two species. These results emphasize the need to test a wide variety of nontarget organisms for impacts from environmental contaminants, since species, even within the same genus or family, can exhibit vastly different effects. Glyphosate, as one of the most widely used herbicides worldwide, is highly researched, with a multitude of studies linking the weed killer to effects on humans, wildlife, and soil ecosystems. Since simultaneous application of glyphosate and urea frequently occurs in agriculture, the effects of this mixture on earthworms are crucial for understanding the overall impacts on soil health. In exposing the two species to the individual compounds and as a mixture, the authors report increased glyphosate residues in earthworm gut contents, reduced body weight, aggravated intestinal tissue damage, sharply decreased digestive […]

(Beyond Pesticides, October 29, 2025) The latest research on bats and beavers, ecosystem services, and biodiversity adds to a wide body of science on the importance of a balanced ecosystem. In both the Bulletin of the National Research Centre and Journal of Animal Ecology, the researchers highlight the interconnectedness not only between wildlife species but to broader ecosystem functioning and human health implications. Researchers in the Journal article add to the growing body of science connecting an abundance of bat species in areas with established beaver dams, highlighting how interconnected wildlife is. The reporting on this recent research coincides with Beyond Pesticides’ 42nd National Forum, The Pesticide Threat to Environmental Health: Advancing Holistic Solutions Aligned with Nature, scheduled for today, October 29. As the author of the article in the Bulletin of the National Research Centre, entitled “The complex web between environmental disruption, pesticide use, and human health: lessons from the bat crisis,†states: “The close relationship between environmental balance, biodiversity, and human health has long been a concern of science and public policy. Disruptions in ecosystems often trigger cascading effects that extend far beyond the original ecological imbalance, affecting agricultural practices, food security, and public health.†Bat Declines and […]

(Beyond Pesticides, October 23, 2025) A global literature review of pesticide residues in marine seaweed, published in Marine Pollution Bulletin, highlights the widespread presence of pesticides in bioindicator species. As vital coastal primary producers, seaweed acts as a key indicator for regional pesticide contamination patterns. The bioaccumulation within seaweed species also threatens consumers, including humans, as the chemicals can biomagnify as they move through the food web. Pesticide contamination in waterways allows residues to bioaccumulate in seaweed species, presenting risks to public health, biodiversity, and ecosystem functioning. In addition to the support seaweeds provide for ecosystems, they provide food sources for a multitude of organisms and are of growing socioeconomic importance. “This systematic review identifies, critically evaluates, and synthesizes recent global literature (2015–2024) on pesticide residues detected in seaweeds to delineate contamination patterns,†the authors share. The findings highlight the harmful impacts of petrochemical pesticides on multiple species. Many aquatic species rely on seaweed as a food source, including fish, sea urchins, crabs, snails, brittle stars, and marine mammals such as manatees and sea turtles. Even bacteria and filter feeders consume seaweed when it is decomposed. Birds and land mammals also consume seaweed, including humans who utilize seaweed in various […]

(Beyond Pesticides, October 8, 2025) A study, Pesticides detected in two urban areas have implications for local butterfly conservation, published in partnership with researchers at Xerces Society for Invertebrate Conservation, University of Binghamton (New York), and University of Nevada, reports widespread pesticide residues in the host plants of butterflies located in green spaces in the cities of Sacramento, California, and Albuquerque, New Mexico. Just 22 of the hundreds of collected samples had no detectable residues, with all other samples containing some combination of 47 compounds of the 94 tested pesticides in the plant tissue. Of the 47 compounds, 4 are neonicotinoid insecticides linked to adverse effects for bee and pollinator populations based on previous peer-reviewed research. The fungicide azoxystrobin and the insecticide chlorantraniliprole were detected at lethal/sublethal concentrations, according to the report authors. “Residential landscapes have high conservation potential for butterflies and other invertebrates,†says Aaron Anderson, co-lead author of the report and pesticide program specialist at Xerces Society for Invertebrate Conservation. He continues: “But, these findings show how pervasive pesticide contamination can be in towns and cities, and underscore that protecting wildlife in these areas includes addressing pesticides.†The report’s results underscore the pervasiveness of pesticide drift and dispel the myth […]

(Beyond Pesticides, September 24, 2025) A novel study of chronic toxicity of the neonicotinoid insecticide thiamethoxam to honey bees (Apis mellifera), published in Insects, finds sublethal effects that threaten the survival of bee larvae and the health of bee colonies. “We evaluated the effects of thiamethoxam on the entire larval development cycle of reproductive bees and conducted a comparative analysis, demonstrating that thiamethoxam significantly alters ecdysone [a hormone that controls molting in insects] and juvenile hormone titers [hormones for insect growth] in both queen and drone larvae, impairing metamorphosis and reproductive development,†the authors state. Risk assessments and scientific literature focus primarily on honey bee workers, rarely including how pesticides can impact queen and drone bees that are necessary for stable colonies. In focusing on this data gap, the researchers reveal that the survival rate of bee larvae decreases gradually with increasing doses of thiamethoxam, adding to the wide body of science on pesticide-related threats to honey bee health. (See Beyond Pesticides’ What the Science Shows on Biodiversity page for more information, as well as Daily News coverage on risk assessments here, here, and here.) Honey bees provide crucial ecosystem services as pollinating insects and play a vital role in […]
