History, conformities to natural laws and prognostication of mass reproduction of basic cabbage pests in Left-bank Forest-steppe of Ukraine

Abstract

Modern looks to possibility of the use of ecological factors (sun activity) for prognostication of mass reproduction of populations of insect pests on the example of basic cabbage pests in the conditions of Left-bank Forest-steppe of Ukraine are analysed. Taking into account actuality of prognostication of mass reproductions of basic leaf-eating pests of cabbage from the order of Lepidoptera (Mamestra brassicacea L., Pieris brassicacea L.), the retrospective analysis of historical data about mass reproductions of the latter in space and time is done and the high-quality prognosis of their appearance on territory of the Poltava area is developed.
