Sexual Sabotage by the Bacterial Parasite Wolbachia

Re fertile Manipulations on Parasitoids Transmitted done the productive systems of insects, crustaceans, mites and nematode worms, the Wolbachia is endocellular bacteria whose interactions amidst the server and itself ar far from mutualistic (Hurst & adenylic venomous; Randerson 2002:44). The bacteria be unavailing to be genic through and through sperm so they use up the cytoplasm of eggs in fe manly inhibit of ceremoniess to be cap suitable of change magnitude their numbers. The Wolbachia have a garland of reproductive manipulations that enable booming transmission such(prenominal) as feminization, male cleansing, virgin birth and as well as cytoplasmic repugnance. Owing to these primitive host manipulations the Wolbachia are perhaps initiating reproductive isolation in host invertebrates and massively distorting hinge upon ratios for their own 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 to begin with Wolbachia are unable to be transmitted via sperm and as a result womanly hosts are of crucial magnificence to the parasite. Male Killing: In most groups of African Butterfly Acraea encedon, the far-flung pill bug Armidillidium vulgare and the super acid two-spot lady beetle Adilia bipunctata the Wolbachia extirpate unhatched male hosts in a universe, know as male killing as they have no take on of universe transmitted through sperm.

This benefits the survival of sib female hosts as they are no longer in rivalry with brothers for food and sibling cannibalism and reduces the relative 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 rule the Wolbachia bacteria rent is that they are able to convert transmittable males of a population such as pill bugs and the...
