New host for the parasitoid Pachycrepoideus vindemmiae (Rondani) (Hymenoptera: Pteromalidae) in Brazil

Occurrence of Pachycrepoideus vindemmiae (Rondani, 1875) (Hymenoptera: Pteromalidae) as a parasitoid of Megaselia scalaris (Loew, 1866) (Diptera: Phoridae) in Brazil.

Phoridae are small or minute flies easily recognized by their humpbacked appearance. The adults are fairly common in many habitats, but occur especially in decaying animal or vegetable matter. Some occur in fungi and some are internal parasitoids (Veríssimo, 1995; Andreotti et al., 2003) of various other insects. Megaselia scalaris (Loew, 1866) (Diptera: Phoridae) is found in various environmen...

Isolation and characterization of polymorphic microsatellite loci for Pachycrepoideus vindemmiae (Rondani) (Hymenoptera: Pteromalidae).

The parasitoid wasp Pachycrepoideus vindemmiae (Rondani) is a common pupal parasitoid of many fly pests that is distributed worldwide. This organism can be used for biological control in orchards or livestock farms. Identifying polymorphic microsatellite loci would be useful for analyzing the population genetic structure of the parasitoid. In the current study, based on a modified biotin-captur...

The ectoparasitic pupal parasitoid, Pachycrepoideus vindemmiae (Hymenoptera: Pteromalidae), attacks other primary tephritid fruit Xy parasitoids: host expansion and potential non-target impact

Pachycrepoideus vindemmiae Rondani is an ectoparasitic idiobiont parasitoid attacking puparia of many cyclorrhaphous Diptera. This study investigated its potential impact as a facultative hyperparasitoid of four other primary tephritid fruit Xy parasitoids in Hawaii, Fopius arisanus (Sonan), Diachasmimorpha longicaudata (Ashmead), Diachasmimorpha kraussii Fullaway, and Psyttalia concolor (Szépl...

Hyperparasitism in a Generalist Ectoparasitic Pupal Parasitoid, Pachycrepoideus vindemmiae (Hymenoptera: Pteromalidae), on Its Own Conspecifics: When the Lack of Resource Lead to Cannibalism

Hyperparasitism is a normal behavior of parasitoids, which often happens among species. Conspecific hyperparasitism, such as some kinds of heteronomous hyperparasitic behaviors, has been only reported in some species belonging to Aphelinidae. In this article, the conspecific hyperparasitism of Pachycrepoideus vindemmiae (Pteromalidae) is reported, with Drosophila puparia as hosts. Hosts were ex...
