%X Lasioderma serricorne (F.) (Coleoptera: Anobiidae), is generally considered one of the most destructive insects in cigarette manufacturing. Beta-cyfluthrin, as a synthetic pyrethroid, has always been an effective insecticide for the management of L. serricorne in cigarette manufacturing factories and food storage or processing factories. In this study, bioassays were conducted to evaluate the sensitivity of L. serricorne (LSH) collected from the Hefei cigarette manufacturing factory to beta-cyfluthrin and its substitute for imidacloprid. The results showed that the LSH strain had developed high resistance to beta-cyfluthrin, but was highly susceptible to imidacloprid. The LSH strain showed no cross-resistance to imidacloprid with a cross-resistance ratio of only 1.00-1.33 folds. In addition, the 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 efficacy by reducing the detected L. serricorne rate by up to 100%. Our work is important in recognizing insect resistance at an early age, developing relevant tactics for effective insect control, and providing more potential insecticide options for managing other Coleoptera insects resistant to pyrethroid. The results also showed that space spray with imidacloprid aerosol in a confined space had significant potential to control stored-product pests.
