【Abstract】 In recent decades ,one of the attentions of insect ecology have been paid to study of the plant-insect interactions,which focused on the delicate relationships of plant allelochemicals with insects.During the evolution ,kinds of perfect adaptive strategies of insects in morphology,behavior,host-specificity,physiology,biochemistry and in the use of these substances by insects etc. have been developed. These adaptations accelaerate the co-evolution of pant-insect interactions and give us some new paths to practics. In this paper,the adaptive strategies of insects to plant allelochemicals and their significance in theory and applicaion are discussed.更多还原
