This study was conducted to evaluate the effectiveness of Trichogramma evanescens Westwood (Hymenoptera: Trichogrammatidae) release with as well as without Bacillus thuringiensis var. kurstaki (Berliner) in biological control of Cydia pomonella (L.) (Lepidoptera: Tortricidae) in the Galaxy Gala apple variety grafted onto M9 rootstock in 2016. Four treatments were analyzed: releasing T. evanescens alone (TE), applying B. thuringiensis var. kurstaki (BT) alone, applying both (TE + BT), and a control (C) without any application at all.
