Pesticide Exposure and Effects on Non-Apis Bees

Bees are essential pollinators of many crops and wild plants, pesticide exposure is one the key environmental stressors affecting their health in anthropogenically modified landscapes. Until recently, almost all information on routes impacts came from honey bees, at least partially because they were only model species required for risk assessments (ERAs) insect pollinators. Recently, there has been a surge research activity focusing effects non- Apis including other social bees (bumble stingless bees) solitary bees. These taxa vary substantially another several important ecological traits, spatial temporal patterns, foraging nesting requirements, degree sociality. In this article, we review current evidence base about pathways consequences We find that insights into bee resulting across biological organizations, landscapes, mixtures, multiple still infancy. The good news promising approaches could be used to advance our understanding, with priority given informing pathways, extrapolating effects, determining how well (limited very few mostly neonicotinoid insecticides under unrealistic conditions) can generalized diversity lifestyles global community. conclude future expand knowledge would also beneficial ERAs wider policy decisions concerning pollinator conservation regulation.

Environmental Sources of Possible Associated Pathogens and Contaminants of Stingless Bees in the Neotropics

Insects, Journal Year: 2025, Volume and Issue: 16(4), P. 350 - 350

Published: March 27, 2025

Stingless bees are crucial for pollination and support diverse ecological relationships, offering economic benefits contributing to enhanced crop yields. Their tropical pollinator status makes them highly sensitive environmental changes disruptions, which could affect their survival, as well pathogens that threaten health. The lack of comprehensive research the scattering reports make it difficult identify contaminants. This review aims provide an overview diseases in stingless bees, examine chemical contaminants products, explore threatened sources. Using PRISMA flowchart, a total 30 articles from 2009 2024 concerning were retrieved. A 15 26 pollutants life expectancy survival rate (mainly genera Melipona Tetragonisca) identified five major areas Neotropics, including Brazil, Mexico, Costa Rica, Australia, Asia. Studies indicated bacterial Pseudomonas, Melissococcus, Lysinibacillus affecting particularly brood, annual colony deaths. Heavy metals, polycyclic aromatic hydrocarbons (PAHs), microplastics have been detected by-products especially honey.

Risk assessment requires several bee species to address species-specific sensitivity to insecticides at field-realistic concentrations

Scientific Reports, Journal Year: 2023, Volume and Issue: 13(1)

Published: Dec. 18, 2023

Abstract In the European registration process, pesticides are currently mainly tested on honey bee. Since sensitivity data for other bee species lacking majority of xenobiotics, it is unclear if and to which extent this model can adequately serve as surrogate all wild bees. Here, we investigated effects field-realistic contact exposure a pyrethroid insecticide, containing lambda-cyhalothrin, seven ( Andrena vaga , Bombus terrestris Colletes cunicularius Osmia bicornis cornuta, Megachile rotundata, Apis mellifera ) with different life history characteristics in series laboratory trials over two years. Our results showed significant species-specific responses pesticide at application rate (i.e., 7.5 g a.s./ha). Species did not group into distinct classes high low mortality. Bumble mason survival was least affected by M. rotundata most individuals dead 48 h after application. medium mortality compared species. Most sublethal effects, i.e. behavioral abnormalities, were observed within first hours some solitary species, example O. A. vaga, higher percentage performed abnormal behavior longer until end observation period. While individual weight explained patterns, differences likely linked additional ecological, phylogenetic or toxicogenomic parameters well. support idea that be substitute species’ may justify usage safety factors. To cover more sensitive larger set should considered risk assessment.

Ecotoxicity of Pesticides Approved for Use in European Conventional or Organic Agriculture for Honeybees, Birds, and Earthworms

Pesticides affect biota inside and outside agricultural fields due to their intrinsic mode of action. This study investigated whether pesticide active substances (AS) approved for conventional agriculture in Europe differ ecotoxicity from AS organic agriculture. The evaluation was based on official ecotoxicological data surrogate honeybee, bird, earthworm species, which also serve as a reference environmental risk assessments the authorization process. In October 2022, 268 chemical-synthetic 179 nature-based were listed EU Pesticide Database. Ecotoxicological only available 254 use 110 results showed higher AS: 79% (201 AS), 64% (163 AS) 91% (230 moderately acutely toxic honeybees, birds, earthworms, respectively, compared 44% (48 14% (15 36% (39 We have considered potential ecotoxicities individual this assessment; actual exposure field, where multiple formulations with other chemicals (including impurities) are applied, will be different.

Insects play an essential role as pollinators of wild flowers and crops. At the same time, in agricultural environments are commonly exposed to pesticides, compromising their survival provision pollination services. Although include a wide range species from several insect orders, information on pesticide sensitivity is mostly restricted bees. In addition, disparity methodological procedures used for different groups hinders comparison toxicity data between bees other pollinators. Dipterans highly diverse order that includes some important Therefore, this study, we assessed two hoverflies (Sphaerophoria rueppellii, Eristalinus aeneus) one tachinid fly (Exorista larvarum) neonicotinoid insecticide (Confidor®, imidacloprid) following comparative approach. We adapted standardized methodology acute contact exposure honey build dose–response curves calculate median lethal doses (LD50) three species. The consisted applying 1 µL test solution thorax each insect. Sphaerophoria rueppelli was most sensitive (LD50 = 10.23 ng/insect), E. aeneus 18,176 ng/insect) least. then compared our results with those available literature pollinator using distribution (SSD).
