Neonictinoids: dangerous to bees and more, with negative consequences for entire ecosystems

Researchers continue to amass evidence showing the harmful effects of neonictinoids in pesticides.  National Geographic's news report for a general audience gives an overview, and many scientific papers are quickly found with a search on neonictinoids in Web of Science.  Here are a few of the most recent, beginning with two articles in the open access journal PLOS One.

Tan, K., Chen, W., Dong, S., Liu, X., Wang, Y., & Nieh, J. C. (2014). Imidacloprid alters foraging and decreases bee avoidance of predators. PLOS One, 9(7), e102725. doi:10.1371/journal.pone.0102725
Partial abstract: “Concern is growing over the effects of neonicotinoid pesticides, which can impair honey bee cognition. We provide the first demonstration that sublethal concentrations of imidacloprid can harm honey bee decision-making about danger by significantly increasing the probability of a bee visiting a dangerous food source.”
