Physiological and Biochemical Aspects of Interactions between Insect Parasitoids and Their Hosts

摘要

In the present review, available literary data on physiological and biochemical interactions between parasitoids and their hosts are analyzed. In order to achieve successful development inside or on their hosts, parasi-toids widely use various strategies aimed at suppressing host immunity. Suppression agents used by parasitoids include venom and ovarian fluid components as well as symbiotic microorganisms. The influence of parasitoids on the host organism is complicated, covering many physiological functions and inducing changes of the host metabolism and behavior. The influence of ecto- and endoparasitoids on the host organism is analyzed separately.
