Abstract

One complete generation of Simulium vittatum (Zett.) was reared in each of two trials using a Cornell automated rearing system. Insects reared from eggs oviposited in the laboratory by field-collected females constituted the parental generation. The feeding regimen used to rear the parental generations resulted in a shorter mean developmental time, larger adults, and a higher potential fecundity of females than obtained in previous rearings of S. vittatum in this system. Adults of both parental rearings mated and produced offspring with net reproductive rates of 0.048 and 0.027 for the first and second trials respectively. None of the eggs oviposited by F1 adults embryonated, due to the small number of F1 females and the low insemination rates.

Résumé

Une génération complète de Simulium vittatum (Zett.) a été élevée à deux reprises avec le système automatisé d'élevage de Cornell. La génération parentale consistait d'insectes élevés à partir d'oeufs déposés en laboratoire par des femelles capturées à l'extérieur. Le régime alimentaire fourni à la génération parentale a permis une réduction du temps moyen de développement et l'obtention d'adultes plus gros et de femelles dont le potentiel reproducteur était plus élevé, que lors des essais antérieurs d'élevage de S. vittatum avec ce système. Les adultes des deux élevages de parents se sont accouplés et se sont reproduits avec un taux net de remplacement de 0.048 et 0.027, respectivement, pour le premier et le second essai. Aucun des oeufs déposés par les adultes de la F1 n'a produit d'embryon, dû au petit nombre obtenu de femelles de F1 et aux faibles incidences d'insémination.
