(Beyond Pesticides, June 26, 2025) A review article in Nature Reviews Earth & Environment highlights how the pesticides used in global crop production pose risks to ecosystems and human health through multiple pathways. As the authors note, âOnce applied to crops, pesticides are transported through surface and groundwater flows, atmospheric dispersion and wildlife migration.â Residues in food products, such as fruits and vegetables, as well as bioaccumulation within animals that are consumed as food, also threaten consumers around the world, particularly those relying on international trade. The researchers note: âIn this Review, we summarize the pathways through which synthetic pesticides transcend boundaries, focusing on the impacts of their use in food production… First, we explain how environmental flows contribute to transporting pesticides to regions far from their original source. Next, we examine the role of international food trade in causing transboundary exposure and impact of pesticide use.â As a result, the study calls for prioritizing biodiversity and human health through sustainable methods while maintaining yield to support the growing population. The use of pesticides in chemical-intensive agriculture has exponentially increased since their first synthesis in the late 1930s. âGlobally, pesticides were applied on agricultural land at an average rate of […]

(Beyond Pesticides, June 23, 2025) At the close of National Pollinator week, Beyond Pesticides says in an action that all speciesâand their ecosystemâare threatened by the failure of the U.S. Environmental Protection Agency (EPA) to perform its statutory duties under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and the Endangered Species Act (ESA). Under FIFRA, EPA is required to register pesticides only when they pose no âunreasonable risk to man [sic] or the environment, taking into account the economic, social, and environmental costs and benefits.â Under ESA, EPA must, like all federal agencies, âseek to conserve endangered species and threatened species and shall utilize their authorities in furtherance of the purposesâ of the ESAâwhich are âto provide a means whereby the ecosystems upon which endangered species and threatened species depend may be conserved, to provide a program for the conservation of such endangered species and threatened species, and to take such steps as may be appropriate to achieve the purposes of the treaties and conventionsâ through which âthe United States has pledged itself as a sovereign state in the international community to conserve to the extent practicable the various species of fish or wildlife and plants facing extinction.â In this context, Beyond Pesticides […]

Image: Art Page submission from Sara Grantham, âPollen Song.â (Beyond Pesticides, June 20, 2025) A study in Conservation Genetics, entitled âOrganic farming fosters arthropod diversity of specific insect guilds â evidence from metabarcoding,â showcases the negative effect of chemical-intensive, conventional farm management on insect populations when compared to organically managed meadows. The researchers find that the diversity and biomass of flying insects are higher with organic land management by 11% and 75%, respectively. âWe report a higher diversity on organic meadows in comparison with conventional ones, all over the diversity of flying insects and not only based solely on a few species-poor groups as in previous studies,â the authors state. They continue: âWe found significant richness differences between management types and increased functionality on organic meadows. Our results imply the superiority of organic farming in comparison to conventional farming in the conservation of insect diversity.â The topic of insect biodiversity and the decline of insect populations over the last few decades, also referred to as the insect apocalypse, has been extensively covered by Beyond Pesticides. As previously reported in the Daily News, âContinued Decline in Insect Species Biodiversity with Agricultural Pesticide Use Documented,â insects provide many important services, such as […]

***Featured Art Page submissions for National Pollinator Week, highlighted with the gratitude of Beyond Pesticides: Jesse from Livermore, CA: “Honeybee Pollinating Citrus Blossom”; Yumi from New York, NY: “Birds and the Bees”; Gretchen from Helena, MT: “Butterflies”; Janet from Concord, MA: “Beneath the Big Dipper”; and Trix from Petersburg, NY: “Downy Woodpecker.” (Beyond Pesticides, June 16, 2025) Every year, Beyond Pesticides announces National Pollinator Week to remind eaters of food, gardeners, farmers, communities (including park districts to school districts), civic organizations, responsible corporations, policy makers, and legislators that there are actions that can be taken that are transformative. All the opportunities for action to protect pollinators, and the ecosystems that are critical to their survival, can collectively be transformational in eliminating toxic pesticides that are major contributors to the collapse of biodiversity. This is why Beyond Pesticides starts most discussions and strategic actions for meaningful pollinator and biodiversity protection with the transition to practicing and supporting organic. In launching National Pollinator Week, Beyond Pesticides makes suggestions for individual actions to increase efforts to think and act holistically to protect the environment that supports pollinators. The impact that people have starts with grocery store purchases and the management of gardens, parks, […]

(Beyond Pesticides, June 12, 2025) Thailand-based researchers, in a study published in BMC Veterinary Research, found significant documentation of the occurrence of anticoagulant rodenticide (AR)-induced toxicosis for nontarget organisms in the country. This includes the finding that âall submitted samples of suspected AR exposure in wild animals and exotic pets tested positive for ARs.â These findings signal the pervasive nature in which agrichemical products, including anticoagulant and nonanticoagulant rodenticides, encroach on broader ecosystem health. In an era of federal deregulation and increasing public scrutiny of the role of government in addressing public health, biodiversity, and the climate crisis, advocates continue to call for a wholesale transition to organically managed food and land management systems. Background and Methodology âIn this retrospective study, we investigated the occurrence of AR poisoning in animal specimens analy[z]ed at the Department of Veterinary Pharmacology, Faculty of Veterinary Science, Chulalongkorn University (DVPCU), between 2018 and 2023,â say the authors on the primary focus of this study. âThis study aims to provide a reference dataset for future research on the epidemiology of AR toxicosis in nontarget species.â The authors declared that there were “no competing interestsâ in engaging in this research. The anticoagulant rodenticides were detected through two […]

(Beyond Pesticides, June 5, 2025) A study conducted in Pennsylvania and published in Environmental Entomology highlights threats to nontarget organisms from neonicotinoid insecticide exposure. Using species of ground beetles as an example, the study documents sublethal behavioral effects as well as decreased week-long survival. This research fills a notable gap in current research, with the authors explaining, âPredatory soil arthropods are under-represented in insecticide toxicity studies, severely limiting our understanding of how insecticides affect soil-invertebrate communities in agroecosystems.â Â The researchers continue, âAs a step toward addressing this issue, we conducted novel acute oral, topical, and soil-based toxicity assays on 9 ground beetle species (Coleoptera: Carabidae) in response to the neonicotinoid insecticides clothianidin, thiamethoxam, and imidacloprid.â The nine carabid beetle species, all common to agroecosystems in central Pennsylvania, were exposed to clothianidin, while additional assays with thiamethoxam and imidacloprid were conducted on the two most abundant species. A wide body of science exists that connects neonicotinoid exposure to health effects in a variety of nontarget organisms. Neonicotinoids, a class of neurotoxic insecticides, act as agonists of nicotinic acetylcholine receptors, âpersist under field conditions, and are water soluble, enabling them to translocate into plants and provide systemic protection of seedlings,â the […]

(Beyond Pesticides, May 19, 2025) The Trump administration has removed crucial protections established under the Migratory Bird Treaty Act (MBTA), including those that protect birds from pesticide poisoning. The Migratory Bird Protection Act (MBPA), introduced in May by Rep. Jared Huffman (D-CA) and Rep. Brian Fitzpatrick (R-PA), will restore protections against an âincidental take.â Beyond Pesticides is calling for the protection of migratory birds and the restitution of funds to implement the law. This is not the first time that President Trump has reduced protection for migratory birds. In his first term (2017), the Department of the Interior issued a policy that relieved industries of the requirement to protect birds, and they will no longer be held accountable for bird deaths. In addition, the agency is expected to propose rules to make this policy change permanent. >> Tell your U.S. Representative to cosponsor the Migratory Bird Protection Act (H.R. 3188). MBTA was passed in 1918 to protect migratory birds soon after the last Passenger Pigeon died in captivity, followed by the last Carolina Parakeet. MBTA originally resulted from the loss of birds due to a number of threatsânotably at the time, the collection of bird feathers. It prohibits the take (including killing, […]

(Beyond Pesticides, April 29, 2025) A study in Environment International finds pesticide-induced alterations in the gut microbiota of a farmland raptor species. In collecting blood and cloacal samples from Montaguâs harrier (Circus pygargus) nestlings, the authors âshed light on an overlooked collateral effect of pesticides, i.e., a general modification of gut bacterial assemblages,â which can lead to an imbalance of microorganisms (dysbiosis) and the promotion of potential pathogens, as well as negatively impact the health of birds of prey. âAdditionally, our findings support the ‘One Health‘ framework, stressing the interconnectedness of wildlife, ecosystem, and human health, particularly in pesticide-affected agricultural areas,â the researchers share. âThe gut microbiota is crucial for host health and can be impacted by various environmental disruptions, yet the effects of multiple pesticide exposures on farmland organismsâ microbiomes remain largely unexplored,â the authors state. In the study, they âassessed microbiota changes in a wild apex predator exposed to multiple pesticides in agricultural landscapes,â which âprovides evidence of pesticide impacts on wildlife gut microbiota, highlighting links between pesticide exposure and changes in microbiota composition,â the researchers note. The Montaguâs harrier, as an apex predator, serves as a âbio-sentinelâ or bioindicator species for assessing ecosystem health. âAs top-level predators […]

(Beyond Pesticides, March 20, 2025) An article, published by the National Audubon Society, titled âA Sweeping New Report Shows U.S. Birds Declining Sharply Across a Range of Habitatsâ reviews the latest State of the Birds 2025 report and finds concerning news for bird species across the country. As the article says: âWhether they hop around the prairie, dabble in wetlands, flit through forests, or forage along the shore, birds are suffering rapid population declines across the United States… If these habitats are struggling to support bird species, itâs a sign that theyâre not healthy for other wildlife, or even humansâbut working to restore them will have benefits across ecosystems.” The 2025 edition of the State of the Birds report, showcasing a status assessment of the health of the nationâs bird populations, was cultivated by scientists from bird conservation groups through the U.S. Committee of the North American Bird Conservation Initiative (NABCI). The report notes, âDespite ample evidence that conservation can work, the status quo approach to conservation is not turning bird populations around.â As NABCI shares, the report contains â[s]obering evidence that Americaâs birds continue to decline across the board.â They continue, saying: âBirds are telling us that the habitats […]

(Beyond Pesticides, March 18, 2025) The November 2024 press release by the U.S. Environmental Protection Agency (EPA) for its Rodenticide Strategy includes the final biological evaluation (BE) of 11 rodenticides. Prior to the finalization of the BE, Beyond Pesticides commented to EPAâs Office of Pesticide Programs in early 2024, disagreeing with the categorical no effect (NE) determinations for all freshwater and marine fish, aquatic mammals, aquatic amphibians, aquatic reptiles, and aquatic invertebrates. (See related Daily News and Action of the Week.) The latest scientific literature highlights the impacts of rodenticides on nontarget organisms, including aquatic organisms that the agency failed to evaluate due to harm that was, as EPA says, ânot reasonably certain to occur.â Many rodenticides, intended to target rats, mice, squirrels, nutria, and more, are anticoagulants and stop normal blood clotting. Active ingredients in these pesticides can include bromadiolone, chlorophacinone, difethialone, brodifacoum, and warfarin. Anticoagulant rodenticides (ARs), contrary to the agencyâs assertions, can be transported to aquatic ecosystems, including both freshwater and marine environments. As mentioned in Beyond Pesticidesâ comments, ARs have been detected in raw and treated wastewater, sewage sludge, estuarine sediments, suspended particulate matter, and liver tissues of sampled fish, demonstrating that the aquatic environment experiences […]

(Beyond Pesticides, February 19, 2025) In Global Ecology and Conservation, a study of bat species in organic desert date palm plantations highlights the invaluable ecosystem services these beneficial organisms provide. âBats are crucial in suppressing pest arthropods in agroecosystems, contributing vitally to sustainable agriculture,â the study authors share, which makes supporting bat populations important not just for biodiversity but to help enhance their roles in pest management. Â Â There are various studies connecting organic agriculture and the value it provides for bats and their ecosystem services. (See studies here, here, and here.) While many studies also recognize bat species threatened by pesticides, habitat loss, and climate change, “the importance of bats in agriculture in extreme environments, such as deserts, has received far less attention,â the researchers state. (See previous coverage on pesticide exposure and bats here and here.) They continue, âDate palm plantations represent one of the few productive systems in hyper-arid regions,â noting the studyâs novel design. The date palm, primarily grown throughout the Middle East and North Africa, is one of the earliest domesticated fruit trees. âThe date palm cultivationâs monocultural nature increases susceptibility to pest infestations due to limited plant diversity, involving 112 mite and insect species.â […]

(Beyond Pesticides, February 11, 2025) In a Science of The Total Environment study, scientists test over 100 blue tit (Cyanistes caeruleus) and great tit (Parus major) birdsâ nests for pesticide residues in comparison with the number of dead offspring and unhatched eggs within the nest. Fur-lined nests, from animals treated with ectoparasitic chemicals, expose birds to compounds that can impact reproductive success. The authors found fipronil, a phenyl pyrazole insecticide, in all nests, with the majority also containing the neonicotinoid insecticide imidacloprid and synthetic pyrethroid insecticide permethrin. The data shows higher insecticide levels are linked to increased offspring mortality and threaten biodiversity. This study highlights an important exposure route that is overlooked. âAlthough not all bird species use fur for nest building, a substantial number do, especially cavity-nesting species,â the researchers share. âPrevious research found that 74% of studied woodland bird species in central Europe incorporated fur into their nests.â Many bird species in the U.S. also line their nests with fur, such as black-capped chickadees, tufted titmice, and chipping sparrows. While there is a wide body of science showing reproductive effects from pesticides, the researchers highlight the studyâs novel design, saying, âTo the best of our knowledge, no previous […]

(Beyond Pesticides, February 5, 2025) A study in PLOS One finds acute and chronic impacts of nontarget toxicity on the American burying beetle, Nicrophorus americanus, with neonicotinoid insecticide exposure. In assessing environmentally relevant concentrations of the neonicotinoid insecticide imidacloprid with N. americanus, the researchers note both mortality and behavioral effects that leave the species at high risk of predation. These effects mean the American burying beetle âmay be at greater risk to insecticide exposure than previously thought and vulnerable to episodic, low-dose neonicotinoid exposure,â the authors say. This data sheds important light on a species that has been listed by the U.S. Fish and Wildlife Service (USFWS) as threatened. Burying beetles provide important ecosystem services within the environment such as âburying carrion, increasing available nutrients in soil, and expediting carrion decomposition, while acting as a food source for secondary consumers,â the researchers state. (See more on ecosystem services and beneficial insects here, here, and here.) The N. americanus species are habitat generalists and can be found in grasslands, wet meadows, and forested areas that neighbor agricultural lands and introduce the beetles to pesticide drift and soil residues. While acute and chronic effects vary in duration and severity, pesticide exposure resulting […]

(Beyond Pesticides, January 27, 2025) A public comment period ends today, January 27, 2025, on the U.S. Fish and Wildlife Service’s (FWS) proposed critical habitat rule to protect the rusty patched bumble bee under the Endangered Species Act (ESA). This proposal is responsive to the agency’s 2024 stipulated settlement agreement resulting from years of advocacy and government review and a 2023 court order (NRDC et al. v. U.S. Fish and Wildlife Service, et al.). The proposal follows a 2017 determination by the agency that lists the bumble bee as an endangered species. (See previous Daily News here, here, here, here, and here.) >> Tell the U.S. Fish and Wildlife Service to fully protect the endangered rusty patched bumble bee by finalizing its proposed critical habitat rule with strengthening provisions. The FWS proposal grows out of a species status assessment (SSA) conducted by â15 scientists with expertise in bumble bee biology, habitat management, and stressors (factors negatively affecting the species).â University of Illinois Urbana-Champaign insect ecologist Jason Robinson, PhD concludes in his paper, âProject-specific bumble bee habitat quality assessment,â âAs the first social insect listed under the ESA, the listing of RPBB has required new methods for biological assessment. This species has a complex life cycle requiring a mosaic of different habitat types, […]

(Beyond Pesticides, January 7, 2025)Â A report, released in December 2024 from the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), confronts the problem of âsiloingâ environmental elementsâfood, health, water, biodiversity and climate changeâwhen they instead intersect at a nexus from which each element affects all the others. The problem is essentially that all the elements are part of the same crisis, yet actions to address issues within eachâand, importantly, to resist addressing themâare dealt with in isolation. A proper perspective, gleaned from the report, is to view each element from the center where all parts meet, thus addressing the issues in coordination. According to the IPBES report, â[F]ragmented governance of biodiversity, water, food, health and climate change with different institutions and actors often working on disconnected and siloed policy agendas, resulting in conflicting objectives and duplication of efforts.â The IPBES is an independent body analogous to the Intergovernmental Panel on Climate Change (IPCC) but structured similarly and in close contact with the United Nations (UN). The new report comes at the behest of IPBESâs 147 member countriesâ75 percent of the UNâs membershipâto address the interconnections among the five global crises. The report strongly demonstrates that a holistic, globe-spanning frame […]

Image: Art Page submission from Carol Moyer, “Monarch Butterfly Sideways with Closed Wings.“ (Beyond Pesticides, December 20, 2024) On December 12, the U.S. Fish and Wildlife Service (FWS) opened a public comment period on its proposal to list the monarch butterfly (Danaus plexippus) as a threatened species and to designate critical habitats for the species under the Endangered Species Act of 1973. Under the proposal, the designated habitats would span approximately 4,395 acres throughout overwintering sites in coastal California. The public comment period will be open until March 12, 2025. These suggested protections call attention to the role of chemical-intensive agriculture in affecting populations of pollinators and other beneficial organisms. George Kimbrell, legal director at the Center for Food Safety, shares in a press release that the âmonarch listing decision is a landmark victory 10 years in the making. It is also a damning precedent, revealing the driving role of pesticides and industrial agriculture in the ongoing extinction crisis… But the job isnât done: Monarchs still face an onslaught of pesticides. The Service must do what science and the law require and promptly finalize protection for monarchs.â In the docket, FWS states, âUnder the Act, a species warrants listing if […]

(Beyond Pesticides, December 13, 2024) In October, the U.S. Environmental Protection Agency (EPA) approved the registration applications of BASF Corporation and Mitsui Chemicals Crop & Life Solutions, Inc. for the use of different formulations of the L-isomer of glufosinate (also known as âL-glufosinateâ and âglufosinate-Pâ) as new active herbicidal ingredients. This decision marks one of the first times that EPA has employed its new Herbicide  Strategy Framework to determine the level of mitigation necessary to protect listed species and critical habitat under the Endangered Species Act (ESA). Glufosinate is an organophosphate, with known neurotoxic, reproductive/developmental effects, toxic to aquatic life, and mobile in soils (see Beyond Pesticides Gateway). Scientists have found that formulated glufosinate is generally more toxic to aquatic and terrestrial animals than the technical grade active ingredient. Manufacturers are introducing newer glufosinate products as alternatives for glyphosate-based herbicides, like Bayer/Monsantoâs âRoundupâ and dicamba. The Center for Biological Diversity notes in comments submitted to EPA on this decision, âL-glufosinate has the potential to be used on tens of millions acres of land every year given the crops EPA has proposed to register it on. The scale of potential use is far above most new active ingredients.â This first significant application […]

(Beyond Pesticides, December 3, 2024) In an article in Science, Sabrina Rondeau, PhD reviews her research from 2022-2024 showcasing species of ground-nesting bees, often found in crop fields, that are highly vulnerable to soil pesticide residues and subsequently suffer population declines. Dr. Rondeau, a postdoctoral fellow in the Department of Biology at the University of Ottawa, points to regulatory deficiencies, specifically in environmental risk assessments (ERAs), and the detrimental effects of pesticides on pollinators that threaten food security and biodiversity. âModern intensive agriculture faces a critical paradox: The very pesticides designed to protect our crops endanger essential pollinators that sustain their productivity,â Dr. Rondeau says in the article. Her research (see here, here, here, here, here, and here) identifies important gaps overlooked in current assessments and regulations for bee species, including the common eastern bumble bee (Bombus impatiens) and the hoary squash bee (Xenoglossa pruinosa). Bumble bee queens in temperate climates hibernate for 6-9 months in the soil, while the hoary squash bee is a solitary ground-nesting species. Reference additional Daily News coverage on ground-nesting bees here and here. ââOur findings show that over 70% of wild bee species, which are crucial for pollinating our food crops, face significant risks […]

(Beyond Pesticides, November 6, 2024) An analysis in the International Journal of Research Publication and Reviews emphasizes the role of biodiversity in agriculture, adding to a wide body of science on its importance. The authors, from Western Illinois University in the United States and Rome Business School in Italy, find that biodiversity supports critical ecosystems and organisms needed for sustainable food production. Through literature reviews and case studies, the interconnectedness of agriculture with plant and animal diversity, beneficial insects, soil health, and climate change is highlighted, as well as the need to manage land organically to support biodiversity. Plant and Animal Diversity As the researchers note, âA diverse agricultural system can better absorb shocks and maintain productivity, ensuring food security in the face of uncertainty.â A wide range of species present within ecosystems protects from changing environmental conditions and improves resilience. When farmers use monocultures for their crops, this leads to reduced ecosystem services from beneficial insects and increased vulnerability to pests and diseases. âBy contrast, diverse cropping systems can enhance resilience, providing a buffer against environmental changes and fostering sustainable food production,â the authors say. Research shows that higher plant diversity disrupts pest life cycles and promotes beneficial insects, […]

(Beyond Pesticides, October 25, 2024) To better understand synergistic interactions between multiple stressors, researchers from the Helmholtz Centre for Environmental Research in Leipzig, Germany, analyze exposure to the pyrethroid insecticide esfenvalerate with two nonchemical environmental factors: elevated temperature and food limitation. In their recent publication in Environmental Pollution, the authors find the greatest synergistic effects when Daphnia magna (D. magna) are subjected to esfenvalerate under conditions experienced with climate change including lower food availability and increased temperature. D. magna, also known as daphnids or water fleas, are small planktonic crustaceans that represent an essential part of the food web in lakes and ponds. Impacts on populations of daphnids can lead to effects throughout multiple trophic levels that impact overall biodiversity. As the researchers state, âGlobal biodiversity is declining at an unprecedented rate in response to multiple environmental stressors… A key challenge is understanding synergistic interactions between multiple stressors and predicting their combined effects.â To study this, a Stress Addition Model (SAM), which predicts the cumulative effects of interacting stressors, was utilized and compared to laboratory data using 24-hour-old neonates of D. magna. The organisms were subjected to various conditions, singularly and in combination, including increased temperature, lower quantities of food, […]

(Beyond Pesticides, October 23, 2024) The stark contrast of two political parties emerged around this summerâs reporting of the Project 2025 blueprintâcreated by extreme right-wing conservativesâthat proposes the gutting of environmental and public health policy and implementation. Many political observers say “Project 2025 Presidential Transition Project,” formally titled “Mandate for Leadership: The Conservative Promise,” will be embraced by a second Trump Administration, despite denials that are challenged by insiders as outright lies. While the public became aware of Project 2025 plans to gut the U.S. Environmental Protection Agency (EPA) and many other agencies, the Biden Administration was announcing the emergency ban (see also August 6 announcement), finalized yesterday, of the weed killer Dacthal, exercising an EPA authority that has not been used in 45 years since the banning of 2,4,5-T (50% of the mixture of Agent Orange). With this decision, EPA set an important precedent for proclaiming (i) an unacceptable harm, (ii) its inability to mitigate the pesticideâs hazards with typical risk mitigation measures, and (iii) the availability of alternatives that made the chemical unnecessary. In dramatic contrast, the Trump supporters behind Project 2025 are intent on politicizing science to undermine governmental structures and laws established to protect public health […]

(Beyond Pesticides, October 22, 2024) A recent study, published through the American Chemical Society, analyzes pesticide contamination in riparian soil and plants as a result of flooding from streams in Germany. The authors hypothesize, and then prove, that frequently flooded sites have higher levels of pesticides present due to the pesticides in surface waters contaminating the soil. Results show that the plant vegetation in the contaminated soil then takes up the pesticides, which bioaccumulate and lead to higher contamination that can further cascade throughout the ecosystem and affect terrestrial food webs. â[O]ur study provides evidence from the field that nontarget plant species typical for riparian stream sites receive considerable pesticide exposure via flooding events,â the authors share. This exposure, and subsequent bioaccumulation in plants, threatens the food web, as many riparian plants are a vital food source for insects. According to the authors, flooding events, and their impact on pesticide contamination within soil and plants, are rarely investigated. This study, âmeasur[ing] 98 pesticides and metabolites in plants and root-zone soils sampled at five streams situated in an area in Southwest Germany characterized by intensive agricultural land use,â highlights the differences in contamination between frequently flooded and rarely flooded areas and […]

(Beyond Pesticides, September 11, 2024) A literature review in Environments, written by researchers from South Korea and Ghana, highlights the threat to nontarget species and the biodiversity of insects that occur as a result of agricultural pesticide use. âInsects have experienced a greater species abundance decline than birds, plants, and other organisms, which could pose a significant challenge to global ecosystem management. Although other factors such as urbanisation, deforestation, monoculture, and industrialisation may have contributed to the decline in insect species, the extensive application of agro-chemicals appears to cause the most serious threat,â the authors state. The so-called âinsect apocalypseâ has been reported with one-quarter of the global insect population lost since 1990. The authors, seeking to summarize the decline in insect species richness and abundance, link reliance on petrochemical pesticides and synthetic fertilizers to cascading negative impacts. Insects provide many important services, such as maintaining healthy soil, recycling nutrients, pollinating flowers and crops, and controlling pests. These nontarget and beneficial species are at risk through pesticide exposure, both directly and indirectly, which then affects these essential functions.  âExtensive and indiscriminate pesticide application on a commercial scale affects insect species abundance and non-target organisms by interfering with their growth, […]
