Queen bumblebees exposed to thiamethoxam, a commonly used insecticide, are less likely to lay eggs or build colonies, which according to researchers could lead to extinction. Thiamethoxam or the name brand Syngenta is a broad-spectrum insecticide, which means it is absorbed quickly by plants and transported to all of its parts, including pollen, where it acts to deter insect feeding, including bees and bumblebees. Then the insect (bee) absorb it in its stomach after feeding, or through direct contact. Thiamethoxam can greatly affect how many eggs are laid by queen bees. Researchers found queen bees were less likely to feed, and their eggs developed more slowly after just a two-week exposure to thiamethoxam. Bee lifespan shortened by exposure to neonicotinoids.
