Abstract

Venom of the hyperparasitoid Asaphes lucens (Provancher) immediately paralyzed and stopped development of the larva of the aphid parasitoid Aphidius smithi Sharma and Subba Rao, which did not void a meconium and deteriorated into a soft, blackened mass. On the other hand, venom of a second hyperparasitoid, Dendrocerus carpenteri (Curtis), did not immediately paralyze the larva of A. smithi, which developed up to the prepupal stage, voided a meconium, and remained bright yellow for up to 4–6 weeks before decaying.

Résumé

Le venim de l’hyperparasitoïde Asaphes lucens (Provancher) paralyse immédiatement et interrompt le développement de la larve du parasitoïde Aphidius smithi Sharma et Subba Rao, lequel ne rejette pas de meconium et se transforme en une masse molle et noirâtre. Par ailleurs le venim d’un second hyperparasitoïde, Dendrocerus carpenteri (Curtis), ne paralyse pas immédiatement la larve d’A. smithi, laquelle se développe jusqu’au stade pré-nymphe, rejette le meconium, et demeure jaune brillant pour 4–6 semaines avant de se décomposer.
