Open AccessAdaptive divergence and post-zygotic barriers to gene flow between sympatric populations of a herbivorous mite
Plant-herbivore interactions promote the generation and maintenance of both plant and herbivore biodiversity. The antagonistic interactions between plants and herbivores lead to host race formation: the evolut...

Open AccessGlobally intertwined evolutionary history of giant barrel sponges
Three species of giant barrel sponge are currently recognized in two distinct geographic regions, the tropical Atlantic and the Indo-Pacific. In this study, we used molecular techniques to study populations of...

Open AccessNo adaptation of a herbivore to a novel host but loss of adaptation to its native host
Most herbivorous arthropods are host specialists and the question is which mechanisms drive the evolution of such specialization. The theory of antagonistic pleiotropy suggests that there is a trade-off betwee...

Open AccessIncomplete premating and postmating reproductive barriers between two parapatric populations of a social spider mite
Closely related species with overlap** distributions often show premating reproductive barriers to avoid hybridization. Stigmaeopsis miscanthi (Saito) is a social spider mite infesting Chinese silver grass, and...

The endosymbionts Wolbachia and Cardinium and their effects in three populations of the predatory mite Neoseiulus paspalivorus
Whereas endosymbiont-induced incompatibility is known to occur in various arthropod taxa, such as spider mites, insects and isopods, it has been rarely reported in plant-inhabiting predatory mites (Acari: Phyt...

Females as intraguild predators of males in cross-pairing experiments with phytoseiid mites
Studies on intraguild interactions between phytoseiid species have shown that intraguild predation occurs and is most commonly manifested as adult females of one species feeding on juveniles of another. Whethe...

Morphological, molecular and cross-breeding analysis of geographic populations of coconut-mite associated predatory mites identified as Neoseiulus baraki: evidence for cryptic species?
Surveys were conducted in Brazil, Benin and Tanzania to collect predatory mites as candidates for control of the coconut mite Aceria guerreronis Keifer, a serious pest of coconut fruits. At all locations surveyed...

Open AccessDiversity and recombination in Wolbachia and Cardinium from Bryobiaspider mites
Wolbachia and Cardinium are endosymbiotic bacteria infecting many arthropods and manipulating host reproduction. Although these bacteria are maternally transmitted, incongruencies between phylogenies of host and ...

Open AccessSpider mite (Acari: Tetranychidae) mitochondrial COI phylogeny reviewed: host plant relationships, phylogeography, reproductive parasites and barcoding
The past 15 years have witnessed a number of molecular studies that aimed to resolve issues of species delineation and phylogeny of mites in the family Tetranychidae. The central part of the mitochondrial COI ...

Cardinium symbionts induce haploid thelytoky in most clones of three closely related Brevipalpus species
Bacterial symbionts that manipulate the reproduction of their host to increase their own transmission are widespread. Most of these bacteria are Wolbachia, but recently a new bacterium, named Cardinium, was disco...

Adaptation in the Asexual False Spider Mite Brevipalpus phoenicis: Evidence for Frozen Niche Variation
Because asexual species lack recombination, they have little opportunity to produce genetically variable offspring and cannot adapt to changes in their environment. However, a number of asexual species are ver...

Article
Wolbachia and cytoplasmic incompatibility in the spider mites Tetranychus urticae and T. turkestani
Wolbachia form a group of closely related intracellular Proteobacteria that manipulate reproduction of their arthropod host in various ways. They are widespread in insects, but have not been not looked for in oth...

Effect of genotype on cytoplasmic incompatibility between two species of Nasonia
Cytoplasmically inherited bacteria cause bidirectional incompatibility between two species of the parasitoid wasp genus Nasonia. These bacteria belong to the alpha sub-division of the Proteo-bacteria. Normally, h...

Microorganisms associated with chromosome destruction and reproductive isolation between two insect species
MICROORGANISMS have been implicated in causing cytoplasmic incompatibility in a variety of insect species, including mosquitoes, fruitflies, beetles and wasps1–17. The effect is typically unidirectional: incompat...
