Distribution and Dna Barcoding of Anomalini Beetles (Coleoptera: Scarabaeidae: Rutelinae) in Wheat Fields of Van, Türkiye

Abstract

Anomalini beetles (Coleoptera: Scarabaeidae: Rutelinae) constitute an important group of pests causing significant crop losses in wheat cultivation areas worldwide, including Türkiye. The aim of this study was to comprehensively evaluate the phylogeny, diversity, abundance, and distribution of Anomalini beetles in wheat fields of Van province, Türkiye. Surveys were conducted between April and August 2021, involving monthly sample collection at predetermined locations within six districts: Başkale, Çaldıran, Erciş, Gevaş, İpekyolu, and Tuşba. A Standard sweepnet with a diameter of 35 cm was used to collect samplings. In molecular studies, the mitochondrial COI gene region has been amplified and sequenced using universal primers. Anomalini beetles were detected in all sampling areas except Çatak district. Seven species were identified: Anisoplia austriaca, A. signata, A. lata, Brancoplia leucaspis, Blitopertha nigripennis, Chaetopteroplia segetum, and an unidentified Anisoplia sp. Chaetopteroplia segetum emerged as the most prevalent and abundant species across all districts. Notably, all identified Anomalini species represent the first records for Van province and its environs. While Anomalini beetles were present in the region, their population densities were not considered high enough to cause economic damage. © 2024, Centenary University. All rights reserved.
