Science Bulletins: Bee Deaths Linked to Common Pesticides
everal recent studies have questioned whether exposure to common pesticides might be impairing bee performance and contributing to the observed population declines. Neonicotinoids are a family of pesticides chemically related to nicotine, and are widely used in both large-scale agriculture as well as in home gardening products. This type of pesticide circulates through flowering plants and collects in nectar and pollen. Recent studies conducted by several research groups have shown that even low doses of neonicotinoid pesticides can impair bees’ navigation abilities and reduce the growth of bee colonies. Insects, particularly bees, are the dominant pollinators in temperate regions worldwide. Declines of honey, bumble, and solitary bees may lead to serious repercussions, not only for crop plant production but for the reproductive success of wild flowering plants, as well.
