Subjects of the inquiry: Sap-sucking pests of agricultural crops.
The purpose of the work: Study of common sap-sucking pests in the southern Fergana region.
Tasks of the research. To study the genuses of insects that cause damage by sucking agricultural crops.To Study of seasonal development of aphids in the territory of Southern Fergana. To study the role of entomophages in reducing the amount of plant aphid. Also study the distribution and habitat of pest species. Study of quantitative densities of pests. Determining the damaging features of pests, analysis of changes in plants under the influence of pest species.
Method of inquiry: Aphidological, entomological, ecological and statistical methods were used in the study.
The results obtained and their novelty: Based on the study of the species composition of South Fergana sucking insects: A summary of aphids and food plants in the southern Fergana region is given. For the first time in the agrocenoses of Southern Fergana, the distribution of sap-sucking agricultural crops, distribution features and ecological groupings were analyzed and interpreted. In the conditions of southern Fergana, the rate of increase in the number of cotton-sucking pests under the influence of temperature and humidity was shown. For the first time, a comparative analysis of the afidofauna of the Southern Fergana region was made, and changes in the composition of the species were explained.
Theoretical and practical significance: The results of the research are based on data on the harmful properties of pest species - The peculiarities of the seasonal development of insects that suck agricultural crops in the southern Fergana region are analyzed, which leads to the solution of some problems in this regard. The results of the work carried out during the study, Biology of pest species, ecologically damaging properties can serve as a scientific source.
Level of implementation and economic efficiency: New evidence on the distribution, biology, ecology, characteristics and life processes of agricultural sap-sucking pests in the southern Fergana region has been collected, contributed to the expansion of the available evidence.
Sphere of usage: nature conservation, plant protection, education, researches.
