Abstract: Taking Lasioderma serricorne as the study object, the insecticidal effect of mixed (N2, CO2) atmosphere and low temperature insecticidal method on cigarette production equipment were compared. The results showed that the mixed (N2, CO2) atmosphere could reduce the inner curtain to a lower oxygen concentration (1.0%~1.2%), and the appropriate concentration of carbon dioxide (10%~20%) could stimulate the Lasioderma serricorne to accelerate respiration, and could completely kill the adult and larva of Lasioderma serricorne in a shorter time (10 days); the low-temperature insecticidal method was adopted, which had a better insecticidal effect for hidden danger points of insect sources in partially closed cigarette production workshops.

Key words: mixed atmosphere, nitrogen atmosphere, low-temperature insecticidal technology, Lasioderma serricorne, cigarette production equipment
