RAPD variation within and among species of Melittobia westwood (Hymenoptera: Eulophidae).
The genus Melittobia Westwood comprises several species of microparasitoids and only two of them are know to occur in Brazil up to now: M. australica Girault and M. hawaiiensis Perkins. Nevertheless, the differentiation between these two species using traditional taxonomy is very difficult. In the present study, we used random amplified polymorphic DNA chain reaction (RAPD-PCR) to test for its ...
متن کاملOlfactory Cues in Host Finding by Melittobia digitata (Hymenoptera: Eulophidae)
Chemical signals used by parasitoids to Þnd hosts often originate from the host, its habitat, or both, providing critical cues for locating hosts that are often cryptic or highly dispersed. MelittobiaWestwood are gregarious ectoparasitoids, which primarily attack Trypoxylon politum Say prepupae.HowMelittobia locates its host is unknown, but itmay involve host-related chemical signals. Therefore...
متن کاملWolbachia in two populations of Melittobia digitata Dahms (Hymenoptera: Eulophidae).
We investigated two populations of Melittobia digitata Dahms, a gregarious parasitoid (primarily upon a wide range of solitary bees, wasps, and flies), in search of Wolbachia infection. The first population, from Xalapa, Mexico, was originally collected from and reared on Mexican fruit fly pupae, Anastrepha ludens Loew (Diptera: Tephritidae); the other, from Athens, Georgia, was collected from ...
متن کاملReview of the Biology of Melittobia acasta (Walker) (Hymenoptera: Eulophidae) and Additions on Development and Sex Ratio of the Species
—A list of known hosts of Melittobia acasta and different biological aspects presented in previous literature are summarized and clarified. Development, sex ratio, and offspring production, on wild, facultative, and factitious hosts, and size of stages at different temperatures are shown. In general, development time is equivalent and similar to that of other Melittobia species; however, as tem...
