Abstract:The experiment was done on packaged storage rice, horizontal warehouse plot, shallow along bin and house warehouse by using 2% capsaicin powder to control booklice. The results showed that he effect time of 2% capsaicin powder to control booklice was 3 months, which was 3 times of CK processing in rice packaged indoor experiment. In horizontal warehouse plot experiment, the control effect of 2% capsaicin powder to booklice was better than 3% effective drug to booklice powder, 10% effective drug to booklice emulsifier, 10% Liuyang mold antibiotic. The density of booklice of 2% capsaicin powder processing was only 2/5 times of other three processings. Only 40 kg of 2% capsaicin powder used on the surface layer grain in shallow along bin could control occurrence and harm of booklice and 20 kg was enough to reduce the booklice density of 50% in packaged rice house warehouse.
