| Abstrakt: | Abstract: The foraging and mating behaviour of Euderomphale chelidonii Erdös, 1966, an endoparasitoid of the cabbage whitefly, Aleyrodes proletella (Linné, 1758), is presented. Only some penetrations of the whitefly puparia by the parasitoid ovipositor result in egg laying, but oviposition punctures often are used for host haemolymph extraction; both sexes of the parasitoid feed on host fluids. The courtship repertoire of Euderomphale cheldonii is complex. The most significant features of the mating behaviour of E. cheldonii are: the grasping of the female flagella between the male’s scape and pedicel, followed by the tapping of the female’s flagella by the tarsi of the male’s middle legs. The antero-lateral abdominal glands of E. chelidonii are everted and retracted when the wasp exerts some extra effort (e.g. when forcibly retained or moistened); also the antennal contacts of these glands generally precede the male courtship activity, suggesting an intraspecific signaling function for these glands. |
