Description

This article presents the results of a preliminary study on the distribution, population dynamics, and damage severity of the wheat aphid (Schizaphis graminum Rond.) in wheat fields of the “Oybek Temirov” farm in Furqat district. Visual observations and counts were carried out for  (March 30 – April 26) on 49 hectares of wheat (variety “Yasavul”) [1, 4]. The average aphid density ranged from 5 to 10 individuals per stem, reaching up to 18 individuals in some areas. The damage severity was assessed as weak (2 points). Affected plants showed 10-20% leaf yellowing in the form of small yellow spots [2, 5]. Recommendations for aphid control are also provided.
