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.

Fungicides account for more than 35% of the global pesticide market and their use is predicted to increase in future. While fungicides are commonly applied during bloom when bees likely foraging on crops, whether real-world exposure these chemicals - alone or combination with other stressors constitutes a threat health still subject great uncertainty. The first step estimating risks understand how what extent exposed active ingredients.

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.

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

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.

Advances and knowledge gaps on climate change impacts on honey bees and beekeeping: A systematic review

Global Change Biology, Journal Year: 2024, Volume and Issue: 30(3)

Published: March 1, 2024

Abstract The Western honey bee Apis mellifera is a managed species that provides diverse hive products and contributing to wild plant pollination, as well being critical component of crop pollination systems worldwide. High mortality rates have been reported in different continents attributed factors, including pesticides, pests, diseases, lack floral resources. Furthermore, climate change has identified potential driver negatively impacting pollinators, but it still unclear how could affect populations. In this context, we carried out systematic review synthesize the effects on bees beekeeping activities. A total 90 articles were identified, providing insight into impacts (negative, neutral, positive) beekeeping. Interest change's impact increased last decade, with studies mainly focusing individuals, using empirical experimental approaches, performed at short‐spatial (<10 km) temporal (<5 years) scales. Moreover, environmental analyses based short‐term data (weather) concentrated only few countries. Environmental variables such temperature, precipitation, wind widely studied had generalized negative biological ecological aspects bees. Food reserves, plant‐pollinator networks, mortality, gene expression, metabolism impacted. Knowledge gaps included apiary beekeeper level, limited number predictive perception studies, poor representation large‐spatial mid‐term scales, analysis, understanding pests diseases. Finally, global are an emergent issue. This due their necessity implementing adaptation measures sustain activity under complex scenarios.

Do novel insecticides pose a threat to beneficial insects?

Proceedings of the Royal Society B Biological Sciences, Journal Year: 2020, Volume and Issue: 287(1935), P. 20201265 - 20201265

Published: Sept. 30, 2020

Systemic insecticides, such as neonicotinoids, are a major contributor towards beneficial insect declines. This has led to bans and restrictions on neonicotinoid use globally, most noticeably in the European Union, where four commonly used neonicotinoids (imidacloprid, thiamethoxam, clothianidin thiacloprid) banned from outside agricultural use. While this might seem like victory for conservation, will only benefit populations if newly emerging insecticides do not have similar negative impacts insects.
