Abstract
Two species of female parasitoids,Cardiochiles nigriceps andMicropletis cro ceipes (Hymenoptera: Braconidae) were found to discriminate between superpara sitized and nonparasitized hosts. The source of the host marking pheromone was found to be the alkaline (Dufour’s) gland in both species.
Résumé
Deux espèces de parasites femelles,Cardiochiles nigriceps etMicropletis croceipes (Hymenoptera: Braconidae), sont capables de distinguer les hôtes superparasités et les nonparasités. On a trouvé que la source de la pheromone qui marque les hôtes est la glande alkaline de Dufour dans les deux cas.
