“…Only in the phytoseiid Galendromus occidentalis (Nesbitt) and in some spider mites, the endosymbionts Wolbachia and more recently Cardinium have been demonstrated to mediate unidirectional reproductive incompatibility (Hess and Hoy 1982;Gotoh et al 1995;Johanowicz and Hoy 1996;Breeuwer 1997;Vala et al 2000Vala et al , 2002Vala et al , 2003Gotoh et al 2006;Ros and Breeuwer 2009). Bidirectional incompatibility is assumed to be caused by either negative nuclear-nuclear genes interactions, as has been reported in the spider mite Panonychus mori Yokoyama (Gotoh et al 2005), or infection by different strains of Wolbachia, as is well documented for insects (Laven 1959(Laven , 1967Mercot et al 1995;O"Neill and Karr 1990;Clancy and Hoffmann 1996).…”

Preliminary identification of geographically distinct populations as belonging to the same species (N.paspalivorus) was based on their morphological similarity. However, laboratory studies recently conducted have shown large differences in feeding behaviors and biological characteristics among individuals collected from three geographic origins: Brazil (South America), Benin and Ghana (West Africa). As morphologically similar specimens do not necessary belong to the same species, we evaluated under laboratory conditions, reproductive compatibility between the specimens from three geographic locations to ascertain their conspecificity.Morphological measurements were also made to determine if there is a means of discriminating between them.Inter-population crosses showed complete reproductive isolation between the three geographic populations, but interpopulation discontinuities in morphometric characters were absent. These results indicate that the tested specimens are distinct biological entities despite morphological similarity. Further molecular genetic studies are therefore proposed, including screening for endosymbionts and assessment of genetic differentiation, to determine the cause of reproductive incompatibility and to clarify the taxonomic relationship between those populations.

“…Wolbachia can affect reproduction of spider mites and can cause CI in hosts, as in insects (Breeuwer 1997;Vala et al 2000Vala et al , 2003Perrot-Minnot et al 2002;Gotoh et al 2003Gotoh et al , 2005. On the other hand, there are many examples that Wolbachia infection does not induce any reproductive abnormalities to insect hosts (Hoffmann et al 1994(Hoffmann et al , 1996Giordano et al 1995) or to spider mite hosts (Gomi et al 1997;Gotoh et al 1999Gotoh et al , 2003Perrot-Minnot et al 2002;Xie et al 2006).…”

Wolbachia-induced cytoplasmic incompatibility in Japanese populations of Tetranychus urticae (Acari: Tetranychidae)

et al. 2007

Intracellular bacteria of the genus Wolbachia (alpha Proteobacteria) induce cytoplasmic incompatibility (CI) in many arthropod species, including spider mites, but not all Wolbachia cause CI. In spider mites CI becomes apparent by a reduced egg hatchability and a lower daughter:son ratio: CI in haplodiploid organisms in general was expected to produce all-male offspring or a male-biased sex ratio without any death of eggs. In a previous study of Japanese populations of Tetranychus urticae, two out of three green-form populations tested were infected with non-CI Wolbachia strains, whereas none of six red-form populations harbored Wolbachia. As the survey of Wolbachia infection in T. urticae is still fragmentary in Japan, we checked Wolbachia infection in thirty green-form populations and 29 red-form populations collected from a wide range of Japanese islands. For Wolbachia-infected populations, we tested the effects of Wolbachia on the reproductive traits and determined the phylogenetic relationships of the different strains of Wolbachia. All but one green-form populations were infected with Wolbachia and all strains belonged to the subgroup Ori when the wsp gene was used to determine the phylogenetic relationships of different strains of Wolbachia. Six out of 29 red-form populations harbored Wolbachia and the infected strains belonged to the subgroups Ori and Bugs. Twenty-four of 29 infected green-form populations and five of six infected red-form populations induced CI among the hosts. Thus, CI-Wolbachia strains are widespread in Japan, and no geographical trend was observed in the CI-Wolbachia. Although three red-form populations harbored other intracellular bacteria Cardinium, they did not affect host reproduction.

“…O’Neill et al , 1997; Stouthamer et al , 1999). Wolbachia has been detected in spider mites, and several studies have reported sex ratio alternation (Breeuwer, 1997; Vala et al , 2000, 2003a,b; Gotoh et al , 2003, 2005). Although most of these reported male‐biased sex ratio as cytoplasmic incompatibility, Vala et al (2000, 2003a) reported that infected females produced significantly more female‐biased sex ratios than uninfected (cured) females in T. urticae .…”

1. Extremely female-biased sex ratios are known in the social spider mite species, Stigmaeopsis longus and S. miscanthi . Whether Hamilton's local mate competition (LMC) theory can explain such sex ratios was investigated.2. Significant changes of the progeny sex ratios in the direction predicted by the LMC model were found in both species when the foundress number changed. Therefore, LMC can partly explain the skewed sex ratios in these species.3. When the foundress number increased, the progeny sex ratio was still female biased and significantly different from the prediction of the LMC model for haplodiploidy. Relatedness between foundresses could not fully explain the female-biased sex ratios. Therefore, these results suggest that there are factors other than LMC skewing the sex ratios of these species toward female.
