Effective methods and means of protection grain crops from Eurygaster integriceps put. in the republic of Uzbekistan

Abstract

The most effective methods of protection are described and the results of long-term observations of the dynamics of the number and harmfulness of the Eurygaster integriceps Put on industrial wheat crops in the conditions of Fergana Valley of the Republic of Uzbekistan are presented. A reliable positive correlation dependence of wheat grain damage from the number of Eurygaster integriceps larvae in crops was established. The ways and principles of choosing essential factors in the development of mathematical models for predicting the development and distribution of Eurygaster integriceps, as well as the issues of zoning territories according to their weather and environmental characteristics are given.
