| Abstract: | Objective] The aim was to clear natural enemies, aphids in cotton field and indoor state of Propylaea japonica (Thunb.).Method] We investigated the occurrence of natural enemies and aphids in cotton field, and observed the indoor state of Propylaea japonica (Thunb.).Result] The indoor feeding state of Propylaea japonica (Thunb.) under normal temperature was 28.8 days.There was a peak of Propylaea japonica (Thunb.) adults and larvae in cotton field after five days of aphids stage.So we should relax cotton aphid indexes, and improved the population quantity of Propylaea japonica (Thunb.) to control main insects.Conclusion] The results provide reference for the chemical control of Propylaea japonica (Thunb.). |
