Secondary host changing between aphids (Hemiptera: Aphididae) and their patasitoids in wheat fields of southeast Anatolian region

Abstract

This study carried out in wheat growing areas and natural areas that nearby of wheat fields of Diyarbakır (Yenişehir, Central villages, Plant Protection Research Institute experimental area) and Şanlıurfa (Akçakale, Siverek) provinces in 2014-2015. Studies were conducted during April, May and June by sampling once a week, while in November and February months by sampling once a month, by irregular controlling of 60 different locations. According to the results; 24 aphid species of 18 genera and 10 parasitoid species of 6 genera were determined on 20 plant species [Alopecurus myosuroides Huds; Amaranthus retroflexus L.; Avena fatua L.; Avena sterilis L.; Carduus crispus L.; Centaurea solstitialis L.; Cirsium vulgare (Savi) A-Sw.; Daucus carota L. var. carota; Galium aparine L.; Lens culinaris Medicus; Lolium perenne L.; Lupinus albus L.; Onopordum acanthium L.; Orobanche sp.; Papaver rhoeas L. Silybum marianum (L.) Grtn.); Sonchus oleraceus L.; Triticum aestivum L. Emd. Fri & Pao.; Triticum durum Desf.; Vicia sativa L.]. Determining of Aphids (Hemiptera: Aphididae) and their parasitoid species including specialization of parasitoids to both aphids and host plants, demonstrated once more the importance of richness of natural enemies in Southeast Anatolian region in terms of biological control.
