(Coleoptera: Anobiidae), is generally considered to be one of the most destructive insects in cigarette manufacturing. Beta-cyfluthrin, as a synthetic pyrethroid, has always been an effective insecticide to manage L. serricorne in cigarette manufacturing factories and food storage or processing factories. In this study, bioassays were conducted to assess the sensitivity of L. serricorne (LSH) collected from Hefei Cigarette Manufacturing Factory, to beta-cyfluthrin and its alternative to imidacloprid. Results revealed that the LSH strain had developed high resistance to beta-cyfluthrin, but was highly susceptible to imidacloprid. LSH strain exhibited no cross-resistance to imidacloprid with a cross-resistance ratio only as 1.00 - 1.33 folds. In addition, results of field trials showed that space sprays with beta-cyfluthrin aerosol had failed to kill insects in the cigarette manufacturing area. Imidacloprid, as a substitute for beta-cyfluthrin, showed a high pest control effect with a decreased rate of detected L. serricorne up to 100%. Our work is significant in recognizing insect resistance at an early age, developing corresponding tactics to control insects effectively, and providing more potential insecticide options for managing other Coleoptera insects resistant to pyrethroid. Results also implied that space spray with imidacloprid aerosol in a confined space had significant potential to control stored-product pests. %U https://easletters.com/article/beta-cyfluthrin-resistance-of-cigarette-beetle-lasioderma-serricorne-f-coleoptera-anobiidae-sxcbjbamhk7blcp
