neonicotinoids

A high-tech approach to monitoring bee activity inside the nest reveals how the neonicotinoid imidacloprid impairs colony growth.

The pesticides, which studies show are harmful to bees, will be prohibited in open fields by the end of 2018.

Researchers pinpoint a protein that can metabolize at least one of the insecticides, highlighting a route to identifying compounds that are friendlier to the critical pollinators.

Two large studies find that, in real-world conditions, the insecticides are detrimental to honey bees and bumblebees.

Statisticians debunk a 2013 study by scientists at a Swiss agrochemical company, which had reported that a neonicotinoid pesticide posed a low risk to honeybees.
 

Exposure to neonicotinoid pesticides is correlated with population declines of a large number of wild bee species, according to a field study conducted in the U.K.

Drones exposed to neonicotinoids have fewer viable sperm and show reduced longevity.

A new report says that neonicotinoids are poisonous to some birds at lower concentrations than previously indicated.
