Abstract
Patasson lameerei DeBauche produced an average of 28.5 offspring under 2 temperature regimes usingSitona hispidulus (Fabricius) eggs as hosts. Although its fecundity was not affected by the temperature regimes,P. lameerei lived significantly longer at 6.7/18.3°C than at 21.1°C. When ample hosts were available,P. lameerei produced more offspring during the 1st few hours of its adult life than during any other comparable period. When the parasitoids were denied access to host eggs for 1,2, or 3 days after emergence, they still produced similar numbers of offspring during their 1st 24 h exposure to hosts.
Résumé
Patasson lameerei Debauche a produit une moyenne de 28,5 descendants sous 2 régimes de température, utilisant les œufs deSitona hispidulus (Fabricius) comme hôtes. Bien que sa fécondité n'ait pas été affectée par les régimes de température, la durée de vie deP. lameerei s'est avérée être notablement plus longue à 6,7/18,3°C qu'à 21, 1°C. Lorsqu'un grand nombre d'hôtes était accessible,P. lameerei produisait plus de descendants lors des quelques premières heures de sa vie adulte que lors de toute autre période comparable. Lorsque l'accès des parasites aux œufs hôtes était empêché pour une période de 1,2 ou 3 jours après l'émergence, ceux-ci continuaient à produire des nombres similaires de descendants lors de leurs premières 24 h d'exposition aux hôtes.
