Extract
In July, 1956, a pupa of the imported cabbageworm, Pieris rapae (L.), was found attached to the undersurface of a corn leaf in experimental plots at St. Jean. After the pupa had been incubated at 75°F. for six months, a dipterous parasitic larva emerged and pupated immediately; a tachinid fly emerged two weeks later. The parasite was identified by Mr. J. G. T. Chillcott, Entomology Division, Ottawa, as Phryxe vulgaris (Fall.). P. vulgaris has been reported as a parasite of Pieris rapae, P. brassicae (L.), P. napi (L.), and Vanessa urticae (L.) from many central and northern European countries (Thompson, 1946, pp. 467-469; 1947, p. 598). Aldrich and Webber (1924), Chittenden (1926), and Schaffner and Griswold (1934) reported this parasite from P. rapae in the United States. P. vulgaris has been reported from Canada only on larvae of the armyworm, Pseudaletia unipuncta (Haw.), in Nova Scotia and New Brunswick (Gibson, 1915, p. 14).
