Abstract
The identification of recombinant males inMuscidifurax raptorellus Kogan & Legner, secured from virgin hybrid ♀♀ formed by crossing cohorts from solitary and gregarious, populations, supports chromosomal inheritance of gregarious oviposition behavior. Examination of parasitization behavior in female progeny that had recombinant male fathers, indicated the, existence of recombinant ♂♂. Such ♂♂ also were able to elicit immediate phenotypic changes in their female mating partners, at intensities expected from their genetic character, as previously observed with original parental ♂♂ in this species. Progeny originating from F1 mothers and recombinant fathers demonstrated the highest levels of heterosis, as measured by increased parasitization rates and numbers of eggs laid. Although extranuclear inheritance has not been eliminated, its influence on phenotypic changes in progeny seems minimal.
Résumé
L'identification de ♂♂ recombinants deMuscidifurax raptorellus Kogan & Legner, issus de ♀♀ vierges descendantes de croisements entre populations grégaires et solitaires, a permis la mise à jour d'un déterminisme génétique chromosomique du comportement de grégarité. L'analyse de ce comportement dans la descendance de femelles croisées avec ces ♂♂ recombinants indique également la présence de tels ♂♂. Ces ♂♂ présentent de plus la capacité de provoquer des changements phénotypiques immédiats chez leur partenaire sexuel, et ce avec une intensité en accord avec leurs caractéristiques génétiques, comme ceci a pu être observé chez les ♂♂ de la souche parentale. La descendance issue de croisements entre ♀♀ F1 et ♂♂ recombinants présente un niveau élevé d'hétérosis se traduisant, par une augmentation à la fois du taux de parasitisme et du nombre d'œufs pondus. Bien que l'existence d'un déterminisme extra-chromosomique n'ait pu être écartée; son éventuelle influence sur le phénotype de la descendance semble limité.
