Abstract

Abstract: In order to discuss the new non-toxic approaches of preventing tobacco pests, it is suggested to use bottled CO₂ as a medium to fill the CO₂ gas in the sealed disk, set different parameter gradients, and use live insects to test the effectiveness. The amount of leaf water, appearances and chemical composition were analyzed to evaluate the feasibility of using CO₂ to kill Lasioderma serricorne, to ensure the effects and the quality of tobacco storage. The results show that when the temperature conditions meet the requirements of insect control, and the oxygen concentration in the sealed stack is less than 2% and maintained for more than 35 d during CO₂ treatment, it can effectively kill Lasioderma serricorne.

Key words: Lasioderma serricorne, CO₂, application
