Abstract: he paper summarised the effects of low nitrogen stress of the hosts on population performances and adaptative strategies of sap feeders such as planthoppers and aphids (Homopter). The performances such as few colonised numbers, more of ten styles probing to plant surface, fast feeding rate, longer development duration and higher mortality at immature stages, increased macropters, shorter longevity and undeveloped gonad of sap feeders under nitrogen deficient of the host plants were observed. A variety of ecological and physiological adaptations were adopted by insects for buffering these worse habits, including increasing feed rate, dispersing to more nutritious host plant ,locating on nitrogen rich sites of the plant and modifying plant nutritional physiology.
