Determination of damage Rate of Sunn pests (Eurygaster spp. and Aelia spp.) in Bread Wheat Varieties in Karatay (KONYA) District

Abstract

Abstract The study was carried out in order to determine the damage rate of Sunn pests ( Eurygaster spp. and Aelia spp.) in bread wheat varieties which brought to Konya Commodity Exchange and grown in 33 neighborhoods of Karatay which is the central district of Konya in during 2014-2018 harvest seasons. Samples were taken homogeneously from the bread wheat varieties brought to Konya Commodity Exchange from the neighborhoods with an automatic probe device in accordance with the ISO 24333 Sampling Standard. Analysis sample was taken from this sample in accordance with TS 2974 Wheat Standard and was cleaned and sieved from foreign materials. The grains that have been damaged by sunn pest damage have been determined, selected and weighed, and the damage rate of the grains by mass has been found. Protein and hectolitre values were also determined by measuring the remaining sample on the device working with the Near Infrared Transmission (NIT) principle. As a result of the research; In harvest season between 2014-2018, the average of Sunn pests damage in bread wheat coming from all districts of Karatay District is 1.1%, 0.8%, 0.9%, 0.9% and 1.1%, respectively determined as. It was determined to change that the average of sunn pest rate damage ranged between 0.8-1.5%, protein averages ranged between 12.7-14.1% and hectoliter weights between 76.8-79.4 kg in 2014-2018 harvest seasons.
