Abstract:The Experiments were carried out to study the relationship dynamics of Aphis craccivora population and Vicia faba between physiological stress on the basis of plant-insect experimental system. It is found that V. faba‘s physiological stress can affect A. craccivora population‘s reproduction rate, survival rate and other population characteristics to regulate aphid population dynamics. Vicia faba can transmit and emplify the aphid‘s message which regulats the insect population density. The adaptive process o...
