| Abstract: | The solitary egg parasitoid Telenomus heliothidis Ashmead (Hymenoptera: Scelionidae) was reared from egg to adult in vitro. Both sexes of adults emerged, mated, and the females produced viable offspring in the natural host, Heliothis virescens F. (Lepidoptera: Noctuidae). While the rearing, wasp fitness was influenced by other factors. The presence of teratocytes influenced parasitoid survival and development. In addition, the quantity of medium ingested by larvae affected the survival, xize, longevity, and fecundity of adults.
Résumé L'oeuf isolé parasitoid Telenomus heliothidis (Hymenoptera: Scelionidae) a été obtenu d'un oeuf a un adulte in vitro. Les deux sexes adultes ont surgi, se sont accouplés et les femelles ont reprodui des progeniture viables du milieu naturel, Heliothis virescens (Lepidoptera: Noctuidae). Pendant que le milieu d'élevage etait important dans l'élevage, le bien être de la guèpe a été influence par d'autres facteurs. La présence de tératocytes a influence la survivance et le developpement de la parasite. De plus, la quantité du milieu absorbée par la varve a affecté la survivance, le developpement et la longevité, et la fecondité des adultes. |
