Determination of Predators and Parasitoids of Tuta absoluta (Lepidoptera: Gelechiidae) in Different Tomato Varieties Cultivated in Open Fields in Diyarbakır Province

Abstract

This study was conducted to determine predators and parasitoids of the tomato leafminer [Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae)] in open field tomato cultivation areas in Diyarbakir province during 2021–2022. Threeparasitoids and 10 predator insects were detected in survey areas. The determined parasitoid species were Bracon hebetor (Say, 1836), Bracon didemie Beyarslan, Bracon (Habrobracon) viktorovi Fischer, and the predatory insects Nysius graminicola (Kolenati, 1845), Geocoris megacephalus (Rossi, 1790), Macrolophus costalis, Macrolophus pygmaeus (Rambur) Campylomma diversicornis Reut., Chrysoperla carnea (Stephens), Orius spp., Orius niger (Wolff), Coccinella septempunctata (L.), and Hippodamia variegata (G.). The results of this study are important for biological and integrated pest management in tomato fields. Additionally, it is believed that the maintaining and increasing of the effectiveness of existing natural enemies is crucial in pest control.
