| Secondary metabolites play an important role in searching for host plants and pest for Litchi pests and nantural enemy. It was very important to take further researches on these secondary metabolites. It would help us to understand the mechanism of host selection behavior of Litchi pests and provide new ways for control pest. In this paper, research in chemical oviposition stimulants and attractants, infection factors and mechanism of host selection for Conopomorpha sinensis Bradley and Tessaratoma papillosa Drury were reviewed and discussed, and also discussed the attraction effect of secondary metabolites on Anastatus japonicus.At last袁the paper discussed the prospect of research in Litchi pests and nantural enemy. |
