Abstract: On the basis of experiments,a new set of models about plant's integrative reaction under insects'pres-sure is proposed The models can be divided into two parts:distinguishing reaction model and stress reac-tion model.The former part indicates that plant has one kind of convergent physioIogical stress reaction in adverse situations,no special reaction of distinguishing and stress.The change of secondary metaboliteis only an accompaily phenomenon,The stress reaction model shows that the reaction is established on the plant selfregulation and dynamic metabolic process.The main metabolism and secondary metabolism of plant alternate their phase successively,so that the plant is always in emergeiicy state,in case there is insect's pressure,it will react appropriately to the intensity of the pressure.
