Abstract

A survey of the imported cabbageworm, Pieris rapae (Lepidoptera: Pieridae), in cole crops in Massachusetts found that a Chinese strain of Cotesia rubecula (Hymenoptera: Braconidae), released in 1988, has spread and become the dominant parasitoid of this pest in central and western Massachusetts, with an average of 75% parasitism. The previously dominant parasitoid of this host, Cotesia glomerata (Hymenoptera: Braconidae), has been displaced and is now present only at trace levels (<1% of total parasitism).
