Sexual Sabotage by the Bacterial Parasite Wolbachia

Reproductive Manipulations on Parasitoids Transmitted through the productive systems of insects, crustaceans, mites and nematode worm worms, the Wolbachia is endocellular bacteria whose interactions amidst the waiter and itself ar far from mutualistic (Hurst & adenylic acid; Randerson 2002:44). The bacteria ar unable to be genic through sperm cellatozoan so they invade the cytoplasm of eggs in fe manly master of ceremoniess to be capable of increasing their be. The Wolbachia welcome a variety of generative manipulations that enable successful transmission system such as feminization, phallic cleansing, parthenogenesis and also cytoplasmatic incompatibility. Owing to these extreme host manipulations the Wolbachia are possibly initiating reproductive isolation in host invertebrates and massively distorting sex ratios for their consume advantage (Hurst & vitamin A; Randerson 2002:44; Werren 1997: 1). Reproductive Manipulations of Host Wolbachia are able to manipulate the reproduction mechanisms of its hosts by elicit male killing, feminization, parthenogenesis and also cytoplasmic incompatibility (Hurst & Randerson 2002:44). As mentioned earlier Wolbachia are unable to be communicable via sperm and as a result female hosts are of all-important(a) importance to the parasite. Male Killing: In some groups of African Butterfly Acraea encedon, the widespread pill bug Armidillidium vulgare and the common two-spot chick beetle Adilia bipunctata the Wolbachia eradicate unhatched male hosts in a universe, know as male killing as they view no chance of being transmitted through sperm.

This benefits the endurance of sib female hosts as they are no e ndless in competition with brothers for food! and sibling cannibalism and reduces the incidence mutations from inbreeding. By killing males hosts the Wolbachia are able to increase female numbers in a population, thus improving their chances of being transmitted (Hurst & Randerson 2002:44; Schulenburg et al. 2002:1). Feminisation: Another reproductive regularity the Wolbachia bacteria rent is that they are able to convert communicable males of a population such as pill bugs and the...
