What was found is that its both parasites and pesticides which are causing the bee apocalypse. It turns out at least eight different pesticides are causing bees to become more susceptible to a specific type of parasite, called, Nosema ceranae.
Most disturbing, bees that ate pollen contaminated with fungicides were three times as likely to be infected by the parasite. Widely used, fungicides had been thought to be harmless for bees as they’re designed to kill fungus, not insects, on crops like apples.“There’s growing evidence that fungicides may be affecting the bees on their own and I think what it highlights is a need to reassess how we label these agricultural chemicals,” Dennis vanEngelsdorp, the study’s lead author, told Quartz.
