“…The highly filamentous forms of TI1 observed in A. albopictus cell cultures (Fig. 2 through 4) and the embryonal gut of T. infestans (20) are typical of early cultures of A. nasoniae (15). On the basis of the high 16s rDNA sequence similarity and morphological similarities between TI1 and A. nasoniae, we propose the name "Candidatus Arsenophonus triatominarum" for the "S-endosymbiont" of T. infestans, described as culture TI1 in this study.…”

An intracellular symbiotic bacterium was isolated from the hemolymph of Triatorna infestans and cultured in an Aedes albopictus cell line. 16s ribosomal DNA sequence analysis revealed that the bacterium was a member of the y-3 subgroup of the class Proteobacteria, having 96.2% sequence identity with the most closely related bacterium, Arsenophonus nasoniae, the causative agent of the son-killer trait in the parasitoid wasp Nasonia vitripennis. These bacteria share morphological features and a common tissue distribution and transmission mode. The A. nasoniae-T. infestans symbiont branch represents a lineage of insect symbionts which may be capable of horizontal transmission between phylogenetically distant host insects. We propose that the intracellular symbiont from T. infestans be classified as "Candidatus Arsenophonus triatominarum." The bacterium found in the hemocytes of T. infestans is designated the type strain of this species.

“…The phylogenetic tree (Fig. 6) shows that TI1 is most closely related to A. nasoniae, the causative agent of the son-killer trait in the parasitoid wasp Nusonia vitripennis (15,39). The high 16s rDNA sequence identity (96.2%) between TI1 and A. nasoniae suggest that TI1 may a member of the genus Arsenophonus.…”

“…Early male killing is known in five orders of insect (Coleoptera, Diptera, Hymenoptera, Lepidoptera and Hemiptera). To date, five clades of bacteria have been identified as male-killing agents: in Coleoptera, Rickettsia ( Werren et al 1994;Lawson et al 2001;von der Schulenburg et al 2001), Wolbachia (Hurst et al 1999a;Fialho & Stevens 2000), Spiroplasma ( Hurst et al 1999b;Majerus et al 1999) and Flavobacteria (Hurst et al 1999c); in Diptera, Wolbachia (Hurst et al 2000) and Spiroplasma (Hackett et al 1985); in Hymenoptera, the gamma proteobacterium Arsenophonus nasoniae (Gherna et al 1991); and in Lepidoptera, Wolbachia ( Jiggins et al 2000a;Fujii et al 2001;Dyson et al 2002) and Spiroplasma ( Jiggins et al 2000b).…”

Novel RNA sequences associated with late male killing inHomona magnanima

et al. 2008

View full text Add to dashboard Cite

Maternally inherited female-biased sex ratios have been documented in many invertebrate species. One cause of such biased sex ratios is male killing, i.e. only males die. In most species, male killing occurs during embryonic stages (early male killing) and is associated with cytoplasmic bacteria, including Wolbachia, Spiroplasma, Rickettsia, Flavobacteria and gamma proteobacteria. However, the oriental tea tortrix, Homona magnanima, is one of the few species in which male death occurs in the larval or pupal stage, and is thus an example of late male killing. We partially purified the agent causing late male killing in H. magnanima and showed that it consists of two RNA sequences. This represents an entirely novel agent causing late male killing.

“…In mosquitoes infected with certain microsporidians, death of the males occurs during the fourth or later instar larvae (late male killing, Hurst, 1991). Various bacteria and microsporidians are known as the causal agents of the male killing trait (Hackett et al, 1986;Gherna et al, 1991;Hurst, 1991;Werren et al, 1994;Balayeva et al, 1995;Hurst et al, 1997). In contrast, feminization is known only from crustaceans.…”

Female-biased sex ratio in the Asian corn borer, Ostrinia furnacalis: evidence for the occurrence of feminizing bacteria in an insect

1998

The maternally inherited, female-biased sex ratio in many arthropods has been attributed to infection with micro-organisms. Male killing, thelytoky and feminization are recognized as the mechanisms of the bacteria-induced sex ratio distortion in arthropods. A sex ratio distortion towards the female has been found in the Japanese population of the Asian corn borer Ostrinia furnacalis (Lepidoptera). In the present study, inheritance of the sex ratio distortion in the Asian corn borer and its underlying mechanism were investigated. Two of the 13 field-collected females produced all-female offspring. The female-biased sex ratio was maternally inherited for three generations. There was no difference in egg hatchability between thelygenic and normal crosses. Treatment with tetracycline for two generations resulted in production of only male offspring. Considering the sex determination system in lepidopteran insects, it was concluded that chromosomal males are feminized by a cytoplasmic agent(s), most probably parasitic bacteria. This is the first report of the occurrence of feminizing bacteria in insects. The sex ratio distorter was considered to occur at low frequency in the Asian corn borer population.
