Abstract

Thelytokous reproduction was developed and fixed in arrhenotokous Muscidifurax raptor Girault and Sanders by mating hybrid females, of interhemispheric strains, with naturally occurring males of M. uniraptor Kogan and Legner. A change in ovipositional behavior was shown by these mated hybrid females which subsequently produced thelytokous Fx offspring for 10 generations. Sperm depletion and extranuclear factors are considered.

Résumé

La reproduction de thélytokous a été développée et fixée dans l’arrhenotokous Muscidifurax raptor Girault et Sanders par l’accouplement de femelles hybrides, de torsions interhémisphériques, avec les mâles survenant naturellement de M. uniraptor Kogan et Legner. Un changement dans le comportement de ponte a été montré par ces femelles hybrides accouplées. Ce changement produisit subséquemment des descendants thélytokous Fx pendant 10 générations. On examine la déplétion de sperme et les facteurs extranucléaires.
