Summary
Larvae of entomophagous insects living endoparasitically induce physiological changes in their hosts. Sometimes this effect of parasitism causes a change in the reaction of the parasitized host to the environmental conditions. In those cases parasitization leads to a differentiation of the host population in ecologically different parts, the mortality of which is noticeably different under natural, but especially under extreme environmental conditions. Thus the parasitic changes in the host become ecologically important for the parasite itself. Some kinds of such reflexive effects are demonstrated by examples.
