Linear Dispersal of the Filth Fly Parasitoid Spalangia cameroni (Hymenoptera: Pteromalidae) and Parasitism of Hosts at Increasing Distances
Release of parasitic wasps (Hymenoptera: Pteromalidae) as biological control agents for house flies and stable flies in livestock confinements has had variable success. In part, this may reflect a lack of knowledge regarding the optimal distance to be used between parasitoid release stations. In the current study, we assessed the effect of linear distance on host parasitism by the wasp Spalangi...
متن کاملTranscriptomics and Identification of the Chemoreceptor Superfamily of the Pupal Parasitoid of the Oriental Fruit Fly, Spalangia endius Walker (Hymenoptera: Pteromalidae)
BACKGROUND The oriental fruit fly, Bactrocera dorsalis Hendel, causes serious losses to fruit production and is one of the most economically important pests in many countries, including China, Spalangia endius Walker is a pupal parasitoid of various dipteran hosts, and may be considered a potentially important ectoparasitic pupal parasitoid of B. dorsalis. However, lack of genetic information o...
متن کاملThe effect of exposure to conspecifics on restlessness in the parasitoid wasp Nasonia vitripennis (Hymenoptera: Pteromalidae)
When habitat quality is variable, there should be strong selection for the ability to detect and respond to the variation. Adult females of the parasitoid wasp Nasonia vitripennis (Walker) are known to increase their restlessness (the proportion of time in locomotion) both during and after exposure to a poor quality host. Doing so provides a mechanism for leaving a poor host and potentially fin...
متن کاملMate Location and the Onset of Sexual Responsiveness in the Parasitoid Wasp Spalangia endius (Hymenoptera: Pteromalidae)
In some animals, transformation to the adult stage occurs in a hidden location, such as a burrow or a host. Males that can locate hidden females sooner, e.g., before they emerge, may have amating advantage, particularly if the females are ready tomate.Whether males locate pre-emergent females and whether pre-emergent females will mate was examined in the parasitoid wasp Spalangia endiusWalker. ...

Ann. EntomoI. Soc. Am. 90(6): 814-824 (1997) ABSTRACT Polymerase chain reaction-restriction fragment length polymorphism (PCRRFLP) and sequencing analyses were used to characterize an amplicon of -625 bp in 4 of the 5 nominate species of Muscidijilrax Girault & Sanders, pupal parasitoids of muscoid Hies. A single polymorphic nucleotide site was observed among 2 samples of M. raptOr Girault & Sa...
