Abstract

Studies were conducted to compare adult longevity, number of host eggs parasitized and temporal pattern of oviposition of four species of Trichogramma, T. brasiliensis Ashmead, T. chilonis Ishii, T. minutum Riley and T. japonicum Ashmead. Parasitoids were reared on eggs of Corcyra cephalonica St. at 27 ± 2°C and 60 ± 5% r.h. With the exception of T. chilonis, females lived longer than males. The only thelytokous species, T. brasiliensis had the highest longevity and fecundity. However, T. chilonis was observed to lay more than 50% of its eggs on its first day of emergence. Of the four species, T. japonicum exhibited the shortest longevity and lowest fecundity.

Résumé

Des études ont été menées pour comparer la longevité de l'adulte, le nombre d'oeufs parasité et le type d'oviposition chez quatre espèces de Trichogramma, à savoir T. brasiliensis Ashmead, T. chilonis Ishii, T. minutum Riley et T. japonicum Ashmead, T. chilonis Ishii, T. minutum Riley et T. japonicum Ashmead. Les parasitoides furent élévés sur des oeufs de Corcyra cephalonica St. à 27 ± 2°C et 65 ± 5% r.h. A l'exception de T. chilonis, les femelles vivaient plus longtemps que les males. T. brasiliensis, la seule espèce à caractére thelytoque avait la plus forte fécondité et longevité. Toutefois, T. chelonis pondait plus de 50% de ses oeufs au cours du premier jour aprés émergence. De toutes les quatre espèces, T. japonicum a montré la plus courte longevité et la plus faible fécondité.
