Increased male fertility in Tribolium confusum beetles after infection with the intracellular parasite Wolbachia

Article Abstract:

The females of the flour beetle Tribolium confusum, when infected by the cytoplasmically inherited microorganism Wolbachia pipientis, yield less offsprings than uninfected female beetles. However, the infected male beetles exhibit a large level of fertility characteristics than the uninfected males, indicating that the Wolbachia acts as a sexually selected trait. The increase in male fertility enables the rapid spread of the Wolbachia among the beetles.
