Плотность популяции как регулятор динамики численности калифорнийской щитовки (Quadraspidiotus perniciosus Comst.)

Abstract

A direct dependence is established between the density of the Quadraspidiolus perniciosus C o m s t. population and such indices as the Q. perniciosus death rate and larva movement velocity. An imerse relationship is determined between the population density and fecundity on the one hand and body weight on the other.
