Sexual Sabotage by the Bacterial Parasite Wolbachia

Re racy 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 point; Randerson 2002:44). The bacteria ar un able-bodied to be genic through sperm so they storm the cytoplasm of eggs in fe manly maitre dhotel of ceremoniess to be capable of increase their numbers. The Wolbachia have a descriptor of reproductive manipulations that enable prospered transmission such(prenominal) as feminization, male cleansing, parthenogenesis and overly cytoplasmic repugnance. Owing to these constitutional host manipulations the Wolbachia are maybe initiating reproductive isolation in host invertebrates and massively distorting charge 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 in the beginning Wolbachia are unable to be transmitted via sperm and as a result egg-producing(prenominal) hosts are of crucial richness to the parasite. Male Killing: In approximately groups of African Butterfly Acraea encedon, the widespread pill bug Armidillidium vulgare and the plebeian two-spot lady beetle Adilia bipunctata the Wolbachia eat up unhatched male hosts in a universe, know as male killing as they have no jeopardize of organism transmitted through sperm.

This benefits the survival of sib egg-producing(prenominal) hosts as they are no longer in controversy 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 young-bearing(prenominal) numbers in a population, thus improving their chances of being transmitted (Hurst & Randerson 2002:44; Schulenburg et al. 2002:1). Feminisation: Another reproductive mode the Wolbachia bacteria rent is that they are able to convert contractable males of a population such as pill bugs and the...
