The morphology characteristic of cabbage butterfly is introduced, which is also compared with the morphology characteristic of the other insects such as cabbage moth (Plutella maculipennis), cabbage webworm (Hellula undalis Fabricius). The occurrence law, living habit and selection of prevention pesticides against cabbage butterfly in China are summarized, which will provide the basic information of cabbage butterfly in China for worldwide further research on cabbage butterfly.展开更多
