Биологические параметры особей популяций насекомых и динамика их численности

Abstract

The method of biological parameters of the investigated population is suggested for improvement of the procedure and technique of predicting the dynamics of the quantily ol the main insects — pests of the agriculture. The first results of the researches are presented on the example of Eurygaster in-tegriceps Put. and Caprocapsa pyrlvora D a n і v. An increase in Eurygaster integriceps Put. quantity occurs corresponding to the growth of the individuum weight. Data of the C. pyrlvora caterpillar weight are processed by variation-statistical method. It is established that on the basis of differences in weight of Caprocapsa pyrlvora D a n і v. pupae the females and males can be differentiated. The dimensions of C. pyrlvora coccons and weight of its caterpillars varied considerably for some years. The researches carried out give some notions on one of the methods for detecting the tendency of the quantity dynamics of agricultural pests.
