A cost of Wolbachia –induced sex reversal and female–biased sex ratios: decrease in female fertility after sperm depletion in a terrestrial isopod

Abstract excerpt

A number of parasites are vertically transmitted to new host generations via female eggs. In such cases, host reproduction is an intimate component of parasite fitness and no cost of the infection on host reproduction is expected to evolve. A number of these parasites distort host sex ratios towards females, thereby increasing either parasite fitness or the proportion of the host that transmit the parasite. In...
