Özet

In Turkey, the polyphagous aphid, Myzus persicae Sulz. (Hemiptera: Aphididae) causes economic damages to eggplant. The solitary koinobiont parasitoid, Aphidius colemani Viereck (Hymenoptera: Braconidae) is the mainly used parasitoid and commercially available in greenhouse crops. This study investigated the efficacy of A. colemani to suppress M. persicae on greenhouse grown eggplant during early fall and spring seasons. Both early fall and spring plastic greenhouse experiments showed that A. colemani significantly reduced aphid densities compared with the control treatment, but aphids' density was over the economic threshold in release treatment. The maximum parasitism rates achieved in early fall and spring experiments were 38.84 and 94.6%, respectively. Various factors, affect the efficacy of the parasitic wasp (A. colemani) on eggplants were discussed. (C) 2018 Friends Science Publishers
