Bumblebees are important pollinators of crops but their number are declining in the past years. In order to understand if exposure to neonicotinoid pesticides is a driver of these declines for a range of bumblebee species, a recent study examined the impacts of field-relevant doses of the neonicotinoid thiamethoxam on wild queens of four bumblebee species. The results showed that field-relevant doses of thiamethoxam can have sublethal impacts on ovary development in multiple species of wild-caught bumblebee queens. Moreover, it was shown that there is differential sensitivity among species which highlights the need of a more well-informed pesticide risk assessment and use. More info: http://bit.ly/2ryeKs5
