Abstract

This study was carried out in order to determine the damage rate of Sunn pest (Eurygaster spp.) and Wheat sting bug (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 province of Turkey, during 2014-2018. Samples were taken homogeneously with an automatic probe device in according with the ISO 24333 Sampling Standard. Analysis samples were taken from these samples in according with TS 2974Wheat Standard and were cleaned and sieved from foreign materials. The grains that have been damaged by Sunn pest (Eurygaster spp.) and Wheat sting bug (Aelia spp.)damage have been determined, selected and weighed, and the damage rate of the grains by mass was calculated. Protein and hectolire 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 seasons between 2014 and 2018, the average of Sunnpests damage in bread wheat coming from all districts of Karatay District were 1.1%, 0.8%, 0.9%, 0.9% and 1.1%, respectively. It was observed that the aveage of Sunn pest (Eurygaster spp.) and Wheat sting bug (Aelia spp.)damage rate 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.
