The capacity of a single Pachycrepoideus vindemiae (Rondani) male to inseminate his sisters adequately in a brood was tested. Ten matings in rapid succession depleted the male's sperm; we found this by alternately examining dissected spermathecae from some females and determining the number of fertilized eggs (daughters) produced by the remaining ...

Host‐feeding and egg maturation by Pachycrepoideus vindemiae
Entomologia Experimentalis et Applicata, 1993AbstractPachycrepoideus vindemiae Rondani (Hymenoptera: Pteromalidae) is a facultative hyperparasitoid of Drosophila parasitoids in Europe. Female P. vindemiae host‐feed from the same hosts into which they lay eggs and this enables them to mature additional eggs. P.

We evaluated the performance of Coptera haywardi (Ogloblin) (Diapriidae) and Pachycrepoideus vindemiae (Rondani) (Pteromalidae), both hymenopteran pupal parasitoids of Anastrepha spp. (Diptera: Tephritidae). Performance was studied by manipulating the following environmental conditions in the laboratory: (1) soil type, (2) soil moisture content, (3 ...

1) Pachycrepoideus vindemiae Rondami, a pupal parasitoid of Drosphila, accepts puparia containing any stage of the larval parasitoids Asobara tabida Nees and Leptopilina heterotoma (Thomson) in experiments in which it could choose between equal number of puparia containing uparasitized Drosophila pupae and puparia containing some stage of the larval ...

Abstract Brachymeria lasus and Pachycrepoideus vindemiae failed to develop in vitro on sterol-free artificial media, and dietary acetate and squalene failed to maintain and/or support growth. The sterols, cholesterol, cholestanol, β-sitosterol, 7-dehydrocholesterol, and cholesterol linoleate were all utilized and maintained larvae of both species ...

Courtship behaviour of a number of species of Pteromalinae (Hym., Pteromalidae) was observed (species are listed in Table I). This paper is a preliminary report about the general properties of courtship in this group of chalcids. Pteromaline males court from a frontal position on the female, the male's front feet being placed on the female's head ...
