Изменчивость биологических показателей развития колорадского жука при оценке устойчивости пасленовых культур к вредителю в различных экологических условиях

Abstract

Such biological parameters as survival and preimaginal development duration vary widely in connection with the intra-specific polymorphism of the Colorado potato beetle, Leptinotarsa decemlineata Say (Coleoptera, Chrysomelidae), and in different ecological conditions. Those parameters are used as the main criteria in evaluation of the solanaceous cultivars for their resistance. So, the methodical requirements to collecting the beetles and their eggs for the laboratory and field experiments could be precised. These conclusions are illustrated by potato, eggplant and tomato examples.
