As the researches of Ukrainian scientists have shown, the changes of annual temperature in the Forest-steppe for a period of 100 years to comparison with the changes of global temperature make 0,7-0,90 C towards warming. The main wreckers of crops are insects, related to the poikilothermal animals therefore the climatic and weather changes define a condition of populations of wreckers and loss of harvest. The purpose of work consisted in a research of long-term dynamics of number and potential losses of harvest from nominees harmful entomocomplexes of winter wheat in the Forest-steppe of Ukraine on climate change. The research consisted of the problems: analysis of databases and carrying out phytosanitary monitoring of winter wheat; definition of indexes warming of climate on the sum of efficient temperatures (SET •100C) and dynamics of hydrothermal coefficient of Selianinov (GTK) of the research of connections of wreckers dynamics of number with the natural warming process of the territory of the Forest-steppe; the analysis of calculated losses of winter wheat harvest from a complex of dominant wreckers on areas of the Forest-steppe. The essential increase of SET for 2005-2017 is established. The dominants of harmful entomocomplexes of winter wheat are divided on sensing and very little sensing types to warming. The trend of long-term dynamics of number of populations has depressive character that has caused the essential decrease of harvest losses.
