The objectives of this research were to detect and identify pollution extent by the levels of metals in honeybees (foragers) (Apis mellifera jemenatica) and beeswax, including some elements such as K, Ca, Na, Mg, Fe, Mn, Cu,…

The neonicotinoid thiamethoxam impairs male fertility in solitary bees, Osmia cornuta

Abstract The ongoing loss of global biodiversity is endangering ecosystem functioning and human food security. While environmental pollutants are well known to reduce fertility, the potential effects of common neonicotinoid insecticides on insect fertility remain poorly understood. Here, we show that field-realistic neonicotinoid exposure can drastically impact male insect fertility. In the laboratory, male and…
