Abstract
Microtonus aethiops (Nees) and M. colesi Drea are parasites of the alfalfa weevil, Hypera postica (Gyllenhal), which are firmly established in New Jersey, Delaware, Pennsylvania, and adjoining states. M. aethiops oviposits in and emerges from weevil adults, while M. colesi oviposits in weevil larvae and emerges from adults. Coles and Puttier (1963) reported the release and establishment of M. aethiops in New Jersey and the initial discovery of Microtonus sp. in Chester County, Pa. This Microctonus sp. (referred to as “Domestic Black” Microtonus by Brunson and Coles (1968)) was later described as a new species by Drea (1968).Keywords
