: These findings highlight that current regulatory assessments may underestimate the risk of systemic insecticides by failing to account for chronic, season-long exposure. Drafting the Long Paper
The paper investigates how long-term exposure to neonicotinoid insecticides affects bumblebee colonies, specifically focusing on queen mortality and reduced foraging efficiency.

: While low doses (less than 10 ppb) typical of seed-treated crops did not immediately kill queens, higher doses (20 ppb to 100 ppb) commonly found in ornamental plants and certain spray-treated crops significantly increased queen mortality by the end of the study.
