摘  要：
[Objective] To compare resistance of the four species cabbage.[Method] With the five point survey method in this experiment,dynamics of Plutella xylostella,Lipaphis erysimi(Kaltenbach) and Phyllotreta striolata(Fabricius) were studied at four varieties of cabbage in the northwest of Hebei Province where is arctic-alpine.[Result]The results showed that Plutella xylostella occurred earlier,and caused more serious damage in earlier stage than in later stage;Lipaphis erysimi(Kaltenbach) increased rapidly in later stage;Phyllotreta striolata(Fabricius) increased steadily from beginning to end.During growth period,and the cabbage is strongly influenced by Plutella xylostella and Lipaphis erysimi(Kaltenbach).[Conclusion]Accroding to the numbers of pest,the capability from strong to weak of insect resistance for four cabbage is Qiufeng,Wanfeng,Beijing four seasons and zhonggan No.8.
