Sexual Sabotage by the Bacterial Parasite Wolbachia

Reproductive Manipulations on Parasitoids Transmitted through the productive systems of insects, crustaceans, mites and tinea worms, the Wolbachia is endocellular bacterium whose interactions amidst the waiter and itself ar far from mutualistic (Hurst & adenylic acid; Randerson 2002:44). The bacteria argon unable to be genic through spermatozoon so they invade the cytoplasm of eggs in fe manly master of ceremoniess to be capable of increasing their add up. The Wolbachia sustain a variety of fruitful manipulations that enable successful contagion such as feminization, male 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 take advantage (Hurst & vitamin A; Randerson 2002:44; Werren 1997: 1). Reproductive Manipulations of Host Wolbachia are able to manipulate the reproduction mechan isms 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 transfer via sperm and as a result female hosts are of significant 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 gentlewoman beetle Adilia bipunctata the Wolbachia eradicate unhatched male hosts in a universe, know as male killing as they realize no chance of being transmitted through sperm.

This benefits the endurance of sib fem ale hosts as they are no perennial in compe! tition 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 order the Wolbachia bacteria rent is that they are able to convert transmittable males of a population such as pill bugs and the...
