Impact of Pachytychius hordei (Brullé) (Coleoptera: Curculionidae) on Wheat Yield Losses in Mardin Province, Türkiye

Abstract

This study was conducted to determine yield losses caused by Pachytychius hordei (Brullé) (Coleoptera: Curculionidae), one of the major pests of cereals, in the bread wheat cultivar Adana 99 grown in four fields with different aspects in Alakuş (Kızıltepe) and Ortaköy (Artuklu) districts of Mardin Province. Each field was divided into four replications, and 25 wheat spikes were randomly collected from each plot. Infested (larvae-damaged) and healthy grains in each spike were counted separately and weighed. The obtained data were subjected to analysis of variance and the LSD₀.₀₅ test to determine significance levels and groupings. In addition, correlation analysis was applied to evaluate pairwise relationships among the examined traits. The results showed that P. hordei laid between 1 and 11 eggs per spike and that one larva was able to develop in each grain. At each location, average yield losses were determined as 91.2 kg/ha at 0.84–1.24 larvae per spike, 128 kg/ha at 1.24–1.56 larvae per spike, 193 kg/ha at 1.56–2.04 larvae per spike, 224 kg/ha at 2.04–2.6 larvae per spike, and 356 kg/ha at 2.6–3.28 larvae per spike. From non-infested grains, yields of 2749 kg/ha in Ortaköy and 2046 kg/ha in Alakuş were obtained. When both infested and non-infested grains were taken into account, average yield losses of 8.8% (268 kg/ha) in Ortaköy and 6.2% (136 kg/ha) in Alakuş were recorded. It was determined that the amount of damage to the crop increased with increasing larval density per spike.
