Terlemezyan, H., Karapetyan, G., Mkrtchyan, H., Ghazaryan, M. & Harutyunyan, H. (2026). Species composition and population of aphids in main fruit agrocenoses of the Armenia and the methods of the pest control against them. Bulg. J. Agric. Sci., 32(1), 181–185
Aphids (Homoptera: Aphidoidea), are rather a numerous group of pests of apple and pear plants in the Lori region of the Republic of Armenia. Some of the aphid species are considerably harmful phytophages in terms of economics.
The present work was compiled on the basis of the research conducted by us in the Lori region, in 2021–2022, during which studies were carried out in the orchards of the most popular apple and pear varieties in the region, aimed at finding out the aphid population on various trees and developing effective measures against them.
According to the results of the conducted studies, 9 species of aphids were recorded on apple and pear trees, among which representatives of the Aphididae family (8 species) predominate, and the Pemphigidae family is represented by one species.
Based on the results of the statistical analysis of the scientific experiments conducted in 2021–2022, we were able to demonstrate that the indicators of the biological efficiency of the insecticides tested against the phytophagous were accurate with the deviation of the indicators of the experimental error (P) and the coefficient of variation (V) being from 2.8% to 5.3% and from 10.3% to 12.5%, respectively.
