DETERMINATION OF COCCIDS IN FRUIT AND ORNAMENTAL TREES OF THE PLAIN, SUB-MOUNTAIN, MID-MOUNTAIN REGIONS OF THE FERGANA VALLEY

Abstract

In the conditions of the development of horticulture and vegetable growing in the regions of the Fergana Valley with the use of high technologies, the study of various groups of the plant and insect world and their adaptations that have appeared during their mutual historical development is the main guarantee of increasing productivity. For this reason, it is considered a requirement today to study the relationship between coccids belonging to the Homoptera order and plants, the effects of coccids on plants, and the effects of plants on coccids, as well as coccids that harm fruit plants. Also it is important to study their distribution, their biological-ecological characteristics. Based on the results obtained in the research, as a result of the interactions between plants and coccids, to determine the new morphological and physiological aspects that appeared in them; by studying the species composition of entomophages of coccids, their effectiveness in reducing the number of their hosts, there is a need to develop theoretical aspects of coordinated protective measures against coccids, pests of fruit plants (1, 2, 3).
