A venom protein of ectoparasitoid Pachycrepoideus vindemiae, PvG6PDH, contributes to parasitism by inhibiting host glucose‐6‐phosphate metabolism

Insect Science, 2021
AbstractTo achieve successful development, female parasitoids, while laying eggs, introduce various virulence factors, mainly venoms, into host insects to manipulate their physiology. Although numerous studies have been conducted to characterize the components of venoms that regulate host immune responses, few systematic investigations have been ...

Span of Female Emergence and Male Sperm Depletion in the Female-biased, Quasi-gregarious Parasitoid, Pachycrepoideus vindemiae (Hymenoptera: Pteromalidae)

Annals of the Entomological Society of America, 1985
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 ...

A venom protein, Kazal‐type serine protease inhibitor, of ectoparasitoid Pachycrepoideus vindemiae inhibits the hemolymph melanization of host Drosophila melanogaster

Archives of Insect Biochemistry and Physiology, 2020
AbstractParasitic wasps inject various virulence factors into the host insects while laying eggs, among which the venom proteins, one of the key players in host insect/parasitoid relationships, act in host cellular and humoral immune regulation to ensure successful development of wasp progeny.

Performance of Two Fruit Fly (Diptera: Tephritidae) Pupal Parasitoids (Coptera haywardi [Hymenoptera: Diapriidae] and Pachycrepoideus vindemiae [Hymenoptera: Pteromalidae]) under Different Environmental Soil Conditions

Biological Control, 2002
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 ...

Host Selection and Sex Allocation By Pachycrepoideus Vindemiae Rondani (Pteromalidae) as a Facultative Hyperparasitoid of Asobara Tabida Nees (Braconidae; Alysiinae) and Leptopilina Heterotoma (Cynipoidea; Eucoilidae)

Netherlands Journal of Zoology, 1982
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 ...
