Sexual Sabotage by the Bacterial Parasite Wolbachia

Reproductive Manipulations on Parasitoids Transmitted through the productive systems of insects, crustaceans, mites and ringworm 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 argon unable to be genic through sperm cell so they invade the cytoplasm of eggs in fe manly master of ceremoniess to be capable of increasing their add up. The Wolbachia suck a variety of fruitful manipulations that enable successful transmittal such as feminization, male person cleansing, parthenogenesis and also cytoplasmic incompatibility. Owing to these extreme host manipulations the Wolbachia are possibly initiating reproductive isolation in host invertebrates and massively distorting sex ratios for their proclaim 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 transmissible via sperm and as a result female hosts are of critical 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 maam beetle Adilia bipunctata the Wolbachia eradicate unhatched male hosts in a universe, know as male killing as they charter no chance of being transmitted through sperm.

This benefits the choice of sib female hosts as they are no monthlong in competition with brothers for food and sibling cannibali! sm 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 manner the Wolbachia bacteria rent is that they are able to convert genetical males of a population such as pill bugs and the...
