Eurygaster Integriceps Puton The Importance Of Biocontrol Agents In Limiting The Number Of Populations

Abstract

In the study in the grain fields in the conditions of the Tashkent oasis Eurygaster integriceps Put. its natural neighbors - eggs and imago parasites, in limiting the number of populations, studied the importance of entomopathogenic fungi. In the conditions of Tashkent oasis in Eurygaster integriceps Put. 3 types of parasitic phase flies: Phasia subcoleoptrata (Linnaeus, 1767), Ectophasia crassipennis (Fabricius, 1794) and Helomiya lateralis Meig. prevalence and their biological efficacy were determined.
