Abstract

The potato aphid, Macrosiphum euphorbiae (Thomas) (Hemiptera: Aphididae), with over 200 known host plants pecies, is one of the most problematic aphids in protected environments worldwide. This study reports for the first time the presence of Aphelinus asychis Walker (Hymenoptera: Aphelinidae), a major parasitoid of M. euphorbiae, in greenhouses in Himachal Pradesh, India. Percent parasitism by A. asychis ranged 2.1–39.3%, reaching its maximum in late November. These findings suggest that A. asychis may be released in augmentative biological control program against M. euphorbiae, which would help reduce pesticide use in Indian vegetable production greenhouses.
