Impact of pesticide use on wild bee distributions across the United States

The decline of many wild bee species has major consequences for pollination in natural and agro-ecosystems. One hypothesized cause the declines is pesticide use; neonicotinoids pyrethroids particular have been shown to pernicious effects laboratory field experiments, linked population a few focal species. We used aggregated museum records, ecological surveys community science data from across contiguous United States, including 178,589 unique observations 1,081 (33% with records States) six families, model occupancy 1995 2015 land use data. While there are numerous causes declines, we discovered that negative pesticides widespread; increase neonicotinoid pyrethroid driver changes hundreds In some groups, high contributes 43.3% decrease probability occurs at site. These results suggest mechanisms reduce (such as integrative pest management) can potentially facilitate conservation. Bees provide important ecosystem services agricultural landscapes, but extent which they affected by on continental scale yet be explored. This study evaluates impact populations States.

Pesticide Risk Assessment in a Changing World

Global Change Biology, Journal Year: 2025, Volume and Issue: 31(4)

Published: April 1, 2025

ABSTRACT Pesticide risk assessments currently rely on surrogate species and focus primarily acute lethality metrics, failing to capture the broader impacts non‐target organisms thus biodiversity. Under directives of regulatory agencies worldwide, this traditional approach overlooks complex interactions between multiple stressors, including climate change, land‐use shifts, pesticide transformation products. must therefore undergo a paradigm shift account for these interactions, which disproportionately affect insect pollinators, other species, biodiversity at large. While prior work has highlighted need move beyond single‐species models, emerging evidence nonlinear stressor ecological consequences products highlight critical gaps in current frameworks. Here, we synthesize insights from recent research propose holistic environmental that integrates evolutionary complexities context global change.

A novel pesticide has lethal consequences for an important pollinator

The Science of The Total Environment, Journal Year: 2024, Volume and Issue: 952, P. 175935 - 175935

Wild bees pollinate crops and wildflowers where they are frequently exposed to pesticides. Neonicotinoids the most commonly used insecticide globally, but restrictions on their use rising pest resistance have increased demand for alternative Flupyradifurone is a novel that has been licenced globally bee-visited crops. Here, in semi-field experiment, we solitary (Osmia lignaria) commercial pesticide formulation (Sivanto Prime) containing flupyradifurone at label-recommended rates. We originally designed experiment examine sublethal effects, contrary our expectations, 100 % of released into pesticide-treated cages died within 3 days exposure, compared 0 control plots. Bees few after initial application survived endured prolonged including lower nesting success, impairment foraging efficiency, higher mortality. These results demonstrate exposure this poses significant threats add growing body evidence indicating can negative impacts wild field-realistic concentrations. In short-term, recommend formulations should be restricted non-flowering while reassessment its safety conducted. long-term, environmental risk assessors continue develop assessments truly holistic incorporate ecological life history traits multiple pollinator species.

Intraspecific diversity is critical to population-level risk assessments

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: Oct. 29, 2024

Environmental risk assessment (ERA) is critical for protecting life by predicting population responses to contaminants. However, routine toxicity testing often examines only one genotype from surrogate species, potentially leading inaccurate assessments, as natural populations typically consist of genetically diverse individuals. To evaluate the importance intraspecific variation in translating populations, we quantified magnitude phenotypic between 20 Daphnia magna clones exposed two levels microcystins, a cosmopolitan cyanobacterial toxin. We observed significant genetic survival, growth, and reproduction, which increased under microcystins exposure. Simulations survival showed that using single tolerance estimates on average failed produce accurate predictions within 95% confidence interval over half time. Whole genome sequencing tested correlations toxicological genomic divergence, including candidate loci prior gene expression studies. found no overall correlations, indicating clonal variation, rather than at genes, predicts population-level toxins. These results highlight incorporating broad without focusing specifically into ERAs more reliably predict how local will respond
