Analysis of the level of colonization of winter wheat by grain aphid (Sitobion avenae F.) in various regions of Poland in 2009–2018

Abstract

The grain aphid (Sitobion avenae F.) is one of the most economically important cereal pests in Europe, causing both direct feeding damage (especially on the ears) and indirect virus transmission. For this reason, systematic monitoring of its intensity on crops and the damage it causes is crucial in the protection of winter wheat and other cereal plants in order to determine the current level of risk. The summary of observations illustrated the changing intensity of the occurrence of grain aphids over selected years in individual regions of the country and provinces.
