Characterization of a 'Bacteroidetes' symbiont in Encarsia wasps (Hymenoptera: Aphelinidae): proposal of 'Candidatus Cardinium hertigii'.
Previously, analysis of 16S rDNA sequences placed a newly discovered lineage of bacterial symbionts of arthropods in the 'Bacteroidetes'. This symbiont lineage is associated with a number of diverse host reproductive manipulations, including induction of parthenogenesis in several Encarsia parasitoid wasps (Hymenoptera: Aphelinidae). In this study, electron microscopy and phylogenetic analysis ...
متن کاملWolbachia-Induced Unidirectional Cytoplasmic Incompatibility and Speciation: Mainland-Island Model
Bacteria of the genus Wolbachia are among the most common endosymbionts in the world. In many insect species these bacteria induce a sperm-egg incompatibility between the gametes of infected males and uninfected females, commonly called unidirectional cytoplasmic incompatibility (CI). It is generally believed that unidirectional CI cannot promote speciation in hosts because infection difference...
متن کاملThe Encarsia flavoscutellum-group key to world species including two new species from China (Hymenoptera, Aphelinidae)
Two new species of Encarsia flavoscutellum-group, E. baoshana Li & Geng, sp. n. and E. longchuana Li & Geng, sp. n. are described from China, and photomicrographs are provided to illustrate morphological characters of the new species. A key to all six described species of the E. flavoscutellum-group is given.
متن کاملIsolation and Characterization of Nine Microsatellite Loci for a Parasitoid Wasp, Encarsia smithi (Silvestri) (Hymenoptera: Aphelinidae)
The parasitoid wasp Encarsia smithi is an important agent in the classical biological control of two species of invasive spiny whiteflies, Aleurocanthus spiniferus and Aleurocanthus camelliae. To evaluate the performance of parasitism indexed by genetic diversity, a highly polymorphic genetic marker is required. In this report, nine microsatellite loci are described for E. smithi. The microsate...
متن کاملPopulation biology of cytoplasmic incompatibility: maintenance and spread of Cardinium symbionts in a parasitic wasp.
Bacteria that cause cytoplasmic incompatibility (CI) are perhaps the most widespread parasites of arthropods. CI symbionts cause reproductive failure when infected males mate with females that are either uninfected or infected with a different, incompatible strain. Until recently, CI was known to be caused only by the alpha-proteobacterium Wolbachia. Here we present the first study of the popul...
