Abstract:

Two classes of factors were distinguished: (A) factors acting on reduction of the numbers of preys within the predator-prey system itself and (B) factors acting from outside on the predator-prey system. In relation to group (A) a discussion is given, using spiders and their mosquito victims as an example of the behaviour of preys in the presence of the predator and the behaviour of predators in relation to their food, under conditions or different density of the components of the system defining these reactions by numerical indices referring to the popu1ation. Examples are given of the inf1uence of these population reactions on the height of indices of prey reduction. In relation to group (B) a short discussion is given of the influence of the weather, structure of vegetation and ,,period of the season” (that is of the development phase of the predator population) on the behaviour of the components of the spider-mosquito system and on the prey reduction.
