These studies will highlight the useful and necessary contribution of stress physiology and toxicology to better understand and predict the ecology of arthropods in a changing world. Studies related to the effect of insecticides on insect pests and nontarget organisms, such as natural enemies, are traditionally accessed by the estimative of lethal effects, through mortality data. Answer (1 of 3): It is desirable to study insect physiology to identify and understand systems that are unique to insects and not found in mammals, birds, reptiles or fish. In order to use insects for these purposes, we have to understand how they function.
