Abstract
Laboratory-rearedBiosteres tryoni (Cameron) reached peak ovarian maturation on the 5th and 7th days after emergence in unmated and mated ♀♀, respectively. When ♀♀ were not allowed to oviposit, contents of the oocytes were hydrolyzed and reabsorbed. However, when hosts were available for oviposition a significant increase of egg maturation rate was noticed.
Mean realized fecundity during the life span was 71.7±8.1 and 69.0±6.7, and mean longevity was 13.5±0.9 and 15.1±0.6 days for mated and unmated ♀♀ respectively.
Résumé
LesBiosteres tryoni élevés en laboratoire atteignaient le sommet de leur maturation ovarienne le 5e jour après l'émergence chez les ♀♀ vierges et le 7e jour chez les ♀♀ accouplées. Quand il n'était pas permis aux ♀♀ de pondre, le contenu des oocytes était hydrolysé et réabsorbé. Cependant, quand des hôtes étaient disponibles pour la ponte, on notait une augmentation significative du taux de maturation des œufs.
La moyenne de la fécondité réalisée durant la vie était 71,7±8,1 et 69,0±6,7 et la longévité moyenne était 13,5±0,9 et 15,1±0,6 jours pour les ♀♀ accouplées et les ♀♀ vierges respectivement.
