Abstract:

The author suggests that the possibility of the elimination of ecological processes and situations creating conditions for “resistance” of the pest population to the pressure of destructive factors should be taken into account in the studies on biological control of pests. Three kinds of processes controlled by the organization of the pest population are presented:1. Change in the model of reduction of prey populations in the presence of predators. Such changes tend to reduce frequency of contacts between individuals of the prey and individuals of the predator.2. Processes (little known at present) of the formation by the prey populations of system which limit to a considerable degree, or even block, the action of predators reducing such a population (Fig. 2). When the system is broken up, the process is stopped and the prey population is exposed to a situation in which its fate depends only on the random chances of encounter with the predator.3. Partial overlapping of the ecological niches of pest and predator (parasite) (Fig. 1). Flexible response of prey population creating such situations in experiments provide an inducement to continue the studies on this phenomenon.
