Abstract

The braconid Pholetesor (= Apanteles) ornigis (Weed) was the major parasite of the spotted tentiform leafminer, Phyllonorycter blancardella (Fabr.), at 21 sites, in 9 counties in southern Ontario. The eulophids Sympiesis sericeicornis (Nees) (12 sites, 6 counties), S. dolichogaster Ashmead (9 sites, 5 counties), S. marylandensis Girault (8 sites, 6 counties) and Pnigalio maculipes (Crawford) (6 sites, 5 counties) were the major chalcidoids recovered. Other species recovered were 10 eulophids, 2 pteromalids, and 2 ichneumonids. The major hyperparasite of P. ornigis was S. sericeicornis, but S. dolichogaster, Habrocytus sp., Catolaccus sp., Gelis sp., and Hypopteromalus sp. were also recovered.

Résumé

Le braconidé Pholetesor (= Apanteles) ornigis (Weed) constitue le principal parasite de la mineuse du pommier, Phyllonorycter blancardella (Fabr.), à 21 emplacements dans 9 comtés du sud de l'Ontario. Les eulophidés Sympiesis sericeicornis (Nees) (12 emplacements, 6 comtés), S. dolichogaster Ashmead (9 emplacements, 5 comtés), S. marylandensis Girault (8 emplacements, 6 comtés) et Pnigalio maculipes (Crawford) (6 emplacements, 5 comtés) ont été les principaux chalcidoidés récupérés. Les autres espèces capturées comprennent 10 eulophidés, 2 ptéromalidés et 2 ichneumonidés. Le principal hyperparasite de P. ornigis est S. sericeicornis, mais S. dolichogaster, Habrocytus sp., Catolaccus sp., Gelis sp. et Hypopteromalus sp. ont également été capturés.
