Neonicotinoid Use, Bee Toxicity, And Actions For California Landscapes, Kendra Mann

Master's Projects and Capstones

Neonicotinoid insecticides are toxic to bees and enhance biodiversity loss due to decreased pollination. Despite the toxicity of neonicotinoids to bees, they are being applied in increasing amounts across California landscapes. To determine what measures can mitigate neonicotinoid effects on bees, I conducted a comparative analysis of toxicity for honey bees (Apis mellifera) vs. wild bees (e.g., Bombus spp. and Osmia spp.) in agriculture and urban landscapes. Then I analyzed alternative actions and current pesticide policies. While more studies are conducted in agricultural landscapes, neonicotinoids are also found at high levels (10 ng/g per bee; 11.2 ng/g in …
