Pyrethroid pesticide use linked with reduced size of worker bumble bees

from Nature World News

Royal Holloway University of London researchers have found that worker bumblebees are getting smaller and hatching earlier than they should, thanks to increased use of pyrethroid pesticide. The chemical is used to prevent bugs from damaging flowering plants. For the study, researchers exposed half of a bumblebee population to the pesticide. The team then tracked the growth of these bees over a four-month period. Microscales were used to measure the weight of a bee. more
