16S rRNA phylogenetic analysis of the bacterial endosymbionts associated with cytoplasmic incompatibility in insects.
TLDR
Initial screening of insects indicates that cytoplasmic incompatibility may be a more general phenomenon in insects than is currently recognized and Lack of congruence between the phylogeny of the symbionts and their insect hosts suggest that horizontal transfer of symbiont between insect species may occur.

Invasion of Europe by the western corn rootworm, Diabrotica virgifera virgifera: multiple transatlantic introductions with various reductions of genetic diversity
TLDR
It was showed that the introduction of WCR into Europe resulted in the redistribution of genetic variance from the intra‐ to the interpopulational level contrary to most examples of multiple introductions, suggesting substantial variation in introduction, foundation and/or establishment conditions. Expand
The role of Wolbachia bacteria in reproductive incompatibilities and hybrid zones of Diabrotica beetles and Gryllus crickets.
TLDR
Wolbachia may have influenced speciation in some members of the genus Gryllus by affecting the degree of hybridization between species, and it is likely that other insect hybrid zones may be influenced by infections with Wolbachia. Expand
Wolbachia infections and the expression of cytoplasmic incompatibility in Drosophila sechellia and D. mauritiana.
TLDR
Experiments indicate that in D. mauritiana expression of the cytoplasmic incompatibility phenotype is determined by the bacterial strain and that the host species harbors a neutral strain of Wolbachia. Expand
Effects of Wolbachia on sperm maturation and architecture in Drosophila simulans Riverside
TLDR
Wolbachia population dynamics during testis development of Drosophila simulans (Riverside) is examined by studying their distribution during the early mitotic divisions of secondary spermatogonial and subsequent meiotic cyst cells, and multiple altered sperm structures were observed during the process of individualization of infected sperm. Expand
Mitotic Defects Associated with Cytoplasmic Incompatibility inDrosophila simulans
TLDR
Findings indicate that embryos derived from cytoplasmically incompatible crosses showed arrested development at different stages, including those with arrested development during early intravitelline mitoses and those whose development had been arrested shortly before hatching. Expand
Genetic diversity of Triatoma infestans (Hemiptera: Reduviidae) in Chuquisaca, Bolivia based on the mitochondrial cytochrome b gene.
TLDR
The phylogenetic relationship and population genetic structure of the haplotypes found in this region, indicate that there is greater variation in this relatively small region of Bolivia than what has been previously reported by studies using the same gene fragment for more distant geographic areas of this country. Expand
Operational criteria for cryptic species delimitation when evidence is limited, as exemplified by North American Entomobrya (Collembola: Entomobryidae)
TLDR
It is proposed that incorporation of the explicit species delimitation criteria developed for this study will result in a substantial advance in the identification and description of species in understudied taxa. Expand
Male-Killing, Nematode Infections, Bacteriophage Infection, and Virulence of Cytoplasmic Bacteria in the GenusWolbachia
TLDR
The dynamics of embryonic male-killing, including effects on insect mating behavior, as well as the distribution and implication of Wolbachia infections in filarial nematodes are reviewed. Expand
Genes, gene flow and adaptation of Diabrotica virgifera virgifera
1 Diabrotica virgifera virgifera has emerged as a major pest of cultivated maize, due to a combination of its high capacity to inflict economic damage, adaptability to pest management techniques andExpand
