“…For example, despite sharing similar Wolbachia strains, the braconid parasitoid wasp Apanteles chilonis, an endoparasitoid of the rice stem borer Chilo suppressalis [49] in the Palearctic, is unlikely to parasitize B. vulgaris or B. auricruda in the Afrotropics. Similarly, Evania appendigaster, a parasitoid of cockroaches [50], is also unlikely to predate on B. ignobilis or B.…”

Background Phylogenetically closely related strains of maternally inherited endosymbiotic bacteria are often found in phylogenetically divergent, and geographically distant insect host species. The interspecies transfer of the symbiont Wolbachia has been thought to have occurred repeatedly, facilitating its observed global pandemic. Few ecological interactions have been proposed as potential routes for the horizontal transfer of Wolbachia within natural insect communities. These routes are however likely to act only at the local scale, but how they may support the global distribution of some Wolbachia strains remains unclear. Results Here, we characterize the Wolbachia diversity in butterflies from the tropical forest regions of central Africa to discuss transfer at both local and global scales. We show that numerous species from both the Mylothris (family Pieridae) and Bicyclus (family Nymphalidae) butterfly genera are infected with similar Wolbachia strains, this despite only minor interclade contacts across the life cycles of the species within their partially overlapping ecological niches. The phylogenetic distance and differences in resource use between these genera rule out the role of ancestry, hybridization, and shared host-plants in the interspecies transfer of the symbiont. Furthermore, we could not identify any shared ecological factors to explain the presence of the strains in other arthropod species from other habitats, or even ecoregions. Conclusion Only the systematic surveys of the Wolbachia strains from entire species communities may offer the material currently lacking for understanding how Wolbachia may transfer between highly different and unrelated hosts, as well as across environmental scales.

“…Although commonly found in cockroach-infested areas in different countries, and in spite of its potential role as a biocontrol agent (Cameron 1957;Lebeck 1991;Fox & Bressan-Nascimento 2006), studies on this wasp are few. In particular, little is known of the larval stages of E. appendigaster.…”

Evania appendigaster is a cosmopolitan wasp that deposits eggs in the oothecae of some species of cockroaches; its larvae then consume the cockroach eggs and embryos. It is a candidate for the biological control of cockroaches, but little is known about its basic biology. Here we describe the external morphology of all immature stages of E. appendigaster and compare them with the larvae of related species. The life cycle of E. appendigaster includes three larval instars, each with 13 body segments. Their mouthparts were generally reduced, except for the mandibles, which were always sclerotized and toothed, and were especially robust in second‐instar larvae. Antennal and mouthpart sensilla were basiconic and difficult to observe. Larvae of E. appendigaster are similar in form to other described evaniid larvae, but quite different from the two available descriptions of larvae of gasteruptiid and aulacid wasps. Further descriptions of evaniid larvae will be useful in determining how widespread this morphology is within the family, and in understanding phylogenetic relationships within Hymenoptera.

“…We used unmated parasitoids in the experiments investigating water balance and survivorship under different RH conditions because transfer of sperm and seminal fluids may affect the gravimetrically determined water balance profile and longevity (see review by Arnqvist and Nilsson, 2000). In the RH preference experiment, we used mated parasitoid wasps because (1) A. hagenowii is a gregarious species that mates soon after emergence (Edmunds, 1955) and, in other gregarious parasitoids, most females mate before dispersal from their natal patch (Martel and Boivin, 2004) and (2) E. appendigaster females that had mated showed greater parasitism activities and fecundity than virgin females (Fox and Bressan-Nascimento, 2006). These mated parasitoids are likely to be engaged more in foraging activities than those unmated individuals.…”
