Monitoring the environment for pollution, pesticides, and pathogens is crucial protecting human, agriculture, overall ecosystem health. Diverse strategies ranging from physical sensors to sentinel species have been used environmental monitoring. The European honey bee, Apis mellifera, a globally managed pollinator that can serve as continuous biomonitoring species. During foraging, bees are exposed contaminants carry them their hives where they be detected quantified. Although individual vulnerable stressors, bee colony whole more resilient accumulate or respond without collapsing.

Nicotinic acetylcholine receptor modulator insecticides act on diverse receptor subtypes with distinct subunit compositions

PLoS Genetics, Journal Year: 2022, Volume and Issue: 18(1), P. e1009920 - e1009920

Insect nicotinic acetylcholine receptors (nAChRs) are pentameric ligand-gated ion channels mainly expressed in the central nervous system of insects. They directed targets many insecticides, including neonicotinoids, which most widely used insecticides world. However, development resistance pests and negative impacts on bee pollinators affect application have created a demand for alternatives. Thus, it is very important to understand mode action these not fully understood at molecular level. In this study, we systematically examined susceptibility ten Drosophila melanogaster nAChR subunit mutants eleven acting nAChRs. Our results showed that there several subtypes nAChRs with distinct compositions responsible toxicity different insecticides. At least three them major seven structurally similar neonicotinoids vivo. Moreover, spinosyns may act exclusively α6 homomeric pentamers but any other Behavioral assays using thermogenetic tools further confirmed bioassay supported idea receptor activation rather than inhibition leads insecticidal effects neonicotinoids.

Ecological traits interact with landscape context to determine bees’ pesticide risk

Nature Ecology & Evolution, Journal Year: 2023, Volume and Issue: 7(4), P. 547 - 556

Published: Feb. 27, 2023

Widespread contamination of ecosystems with pesticides threatens non-target organisms. However, the extent to which life-history traits affect pesticide exposure and resulting risk in different landscape contexts remains poorly understood. We address this for bees across an agricultural land-use gradient based on assays pollen nectar collected by Apis mellifera, Bombus terrestris Osmia bicornis, representing extensive, intermediate limited foraging traits. found that extensive foragers (A. mellifera) experienced highest risk-additive toxicity-weighted concentrations. only (B. terrestris) (O. bicornis) responded context-experiencing lower less land.

Interaction of Insecticides and Fungicides in Bees

Frontiers in Insect Science, Journal Year: 2022, Volume and Issue: 1

Honeybees and wild bees are among the most important pollinators of both cultivated landscapes. In recent years, however, a significant decline in these has been recorded. This decrease can have many causes including heavy use biocidal plant protection products agriculture. The frequent residues bee originate from fungicides, while neonicotinoids and, to lesser extent, pyrethroids popular insecticides detected products. There is abundant evidence toxic side effects on honeybees produced by neonicotinoids, but only few studies investigated because they generally regarded as not being harmful for bees. field, variety substances taken up mixtures their combinations be lethal pollinators, depending specific group insecticide or fungicide. review discusses different major fungicide classes Fungicides inhibiting sterol biosynthesis pathway strongly increase toxicity pyrethroids.

Single and combined exposure to ‘bee safe’ pesticides alter behaviour and offspring production in a ground-nesting solitary bee ( Xenoglossa pruinosa )

Mounting evidence supporting the negative impacts of exposure to neonicotinoids on bees has prompted registration novel ‘bee-friendly’ insecticides for agricultural use. Flupyradifurone (FPF) is a butenolide insecticide that shares same mode action as and been assessed be ‘practically non-toxic adult honeybees' using current risk assessment procedures. However, these assessments overlook some routes specific wild bees, such contact with residues in soil ground-nesters. Co-exposure other pesticides may also lead detrimental synergistic effects. In fully crossed experiment, we possible lethal sublethal effects chronic two used Cucurbita crops, Sivanto Prime fungicide Quadris Top (azoxystrobin difenoconazole), alone or combined, solitary ground-nesting squash ( Xenoglossa pruinosa ). Squash exposed collected less pollen per flower visit, while Sivanto-exposed produced larger offspring.

The European Parliament requested EFSA to develop a holistic risk assessment of multiple stressors in honey bees. To this end, systems-based approach that is composed two core components: monitoring system and modelling are put forward with bees taken as showcase. Key developments the current scientific opinion (including systematic data collection from sentinel beehives an agent-based simulation) have potential substantially contribute future development environmental assessments at larger spatial temporal scales. For monitoring, hives would be placed across representative climatic zones landscapes EU connected platform for storage analysis.
