Study progress in the interactions of feeding behavior of Diamondback moth(Plutella xylostella) and Cruciferae secondary substances.

Secondary metabolites of Cruciferae, especially characteristic compounds, play an important role in searching for host plants and oviposition sites for diamondback moth. 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 diamondback moth and provide new ideas for control pest. In this paper, research in chemical oviposition stimulants and attractants, infection factors and mechanism of host selection for diamondback moth were reviewed and discussed.
