摘  要:
Misumenops tricuspidatus is a predator of Erythroneura sudra and Hyalopterus amygdali .Its selective coefficient varies with the amount change of these two pest populations.When the amount of both insect pest increase or the amount of E.sudra increases while H.amygdali keep unchanged, E.sudra is the priority to be caught.Only when the amount of H.amygdali increase while that of E.sudra keep unchanged and the ratio reached 20/10,the H.amygdali takes the precedence to be caught.
