A new study on Colony Collapse Disorder describing a situation where a combination of poisons makes bees susceptible to a fatal parasite. >Levels for two chemicals were above the dose that would kill half a population within two days, according to the report. Pesticide residue was found on all the pollen samples, including those that the bees apparently collected from nearby wildflowers, according to the report. >The report highlights the diverse cocktail of agricultural chemicals to which domesticated bees are regularly exposed, some of which have been linked to weakened immune system responses in the insects crucial to the world’s food supply. Most studies of domestic honey bees have examined exposure to a single chemical at a time. latimes/news/science/sciencenow/la-sci-sn-bees-pesticides-20130723,0,1291190.story
