Why have parasites promoting mating success been observed so rarely?
Original language description
Using an adaptive dynamics approach to evolution, we explore conditions under which sexually transmitted parasites may evolve an ability to manipulate their hosts so as to increase the hosts? mating rate and thus their own transmission rate. We find thatincreased mating success is less likely to evolve if the host reproduction rate, or the baseline disease transmission rate, is reduced, and the parasite affects just one sex, compared to when it affects both. We also find that it is less likely to evolve if the virulence-transmission trade-off curve is stronger. Finally, if the disease-induced mating enhancement is acting in just one sex, the potential for its evolution increases with the degree of polygyny in the host population.
