Judith E Pasek

Larval parasitism of 3 Psilocorsis species in central Missouri forests averaged 22% for the years 1977-1979. Twenty-three species of parasitoids were reared in the laboratory from the larvae collected. Seventeen species emerged from P. reflexella Clemens, 14 from P. quercicella Clemens, and 10 from P. cryptolechiella (Chambers). The most abundant parasitoids were the braconids Apanteles n. sp., Agathis calcarata (Cresson), and A. cincta (Cresson); the eulophid Elachertus proteoteratis Howard; the ichneumonid Diadegma psilocorsis Walley; and the 3 closely related pteromalids, Perilampus fulvicornis Ashmead, P. prothoracicus Smulyan, and P. n. sp. Elachertus proteoteratis was reared only from P. reflexella. Twenty-three new …
