“…Transitions to parthenogenesis can also be caused by infection with maternally inherited endosymbionts (Stouthamer et al 1990). In haplodiploids, at least three taxa include parthenogenesis-inducing endosymbionts (PI-endosymbionts): Wolbachia, Cardinium, and Rickettsia (e.g., Stouthamer et al 1993;Zchori-Fein et al 2001;Hagimori et al 2006). Presence of PI-endosymbionts can be tested by removing endosymbionts from parthenogenetic females, either by exposing them to high temperatures during early development (Flanders 1945) or by treating them with antibiotics (Stouthamer et al 1990).…”

Changes from sexual reproduction to female-producing parthenogenesis (thelytoky) have great evolutionary and ecological consequences, but how many times parthenogenesis evolved in different animal taxa is unknown. We present the first exhaustive database covering 765 cases of parthenogenesis in haplodiploid (arrhenotokous) arthropods, and estimate frequencies of parthenogenesis in different taxonomic groups. We show that the frequency of parthenogenetic lineages extensively varies among groups (0-38% among genera), that many species have both sexual and parthenogenetic lineages and that polyploidy is very rare.Parthenogens are characterized by broad ecological niches: parasitoid and phytophagous parthenogenetic species consistently use more host species, and have larger, polewards extended geographic distributions than their sexual relatives. These differences did not solely evolve after the transition to parthenogenesis. Extant parthenogens often derive from sexual ancestors with relatively broad ecological niches and distributions. As these ecological attributes are associated with large population sizes, our results strongly suggests that transitions to parthenogenesis are more frequent in large sexual populations and/or that the risk of extinction of parthenogens with large population sizes is reduced. The species database presented here provides insights into the maintenance of sex and parthenogenesis in natural populations that are not taxon specific and opens perspectives for future comparative studies.

“…Here we analyzed the Italian population. The presence of the bacterial symbionts associated with thelytokous reproduction in arthropods, including Cardinium, Wolbachia and Rickettsia (Huigens and Stouthamer, 2003;Hagimori et al, 2006;Hunter and Zchori-Fein, 2006), was checked in 20 Italian females by PCR using the following sets of primers: CLOf and CLOr1 (Weeks et al, 2003), and ChF and ChR (ZchoriFein and Perlman, 2004) for Cardinium 16S rDNA; ftsZf1 and ftsZr1 (Werren et al, 1995) for Wolbachia ftsZ cellcycle gene; Rb-F and Rb-R (Gottlieb et al, 2006) for Rickettsia 16S rDNA.…”

Cardinium is a bacterial symbiont infecting many species of arthropods, and is associated with manipulation of host reproduction. Cardinium is the causal agent of asexual reproduction, or thelytoky, in the chalcidoid parasitoid wasp Encarsia hispida. Feeding antibiotics to the infected adult females results in uninfected male offspring. Here, we show that these males are diploid. Diploid males are extremely unusual in the large hymenopteran superfamily Chalcidoidea, and, to our knowledge, have never before been associated with symbiont infection in this group. These findings indicate that at least in E. hispida, diploidy restoration is a necessary condition but not sufficient to elicit female development. Cardinium is required to feminize diploid male embryos and thus must interact with elements of the host sex determination system. In addition, our data suggest that Cardinium is necessary for the fertility of E. hispida; antibiotic curing of Cardinium reduces offspring production of adult females.

“…Since then, a number of other cases of thelytoky have been associated with the a-proteobacterium Wolbachia, the super-symbiont of arthropods (Werren et al, 2008). In recent years, another a-proteobacterium, Rickettsia, and the Bacteroidetes Cardinium have also been associated with thelytoky (Hagimori et al, 2006 andZchori-Fein et al, 2004, respectively). The diploid males discovered by Giorgini et al (2009) are a result of antibiotic treatment of E. hispida, which naturally carry a thelytoky-inducing Cardinium.…”
