Abstract：Beet armyworm is an important pest on many vegetable crops.After removing the egg masses manually for three times，the control effect on beet armyworm is 88.8 %，93.8 %，89.5 %，78.9 % in the field of hot pepper，Welsh onion，Chinese cabbage，celery.After killing the larva manually for three times，the control effect on beet armyworm is 91.6 %，88.2 %，84.7 %，81.6 %，79.7 %，69.4 % respectively in the field of asparagus，hot pepper，celery，Chinese cabbage，cabbage，Welsh onion.The best insecticide control period for beet armyworm is the end stage of egg hatching.The highest parasitic rate of Telenomus sp is 65.3 % in celery field.The highest parasitic rate of Nomuraea rileyi is 74.3 % in Chinese cabbage field.
