Table 3

Population and evolutionary effects of invasion of a host by male-killing bacteria

Effects on population level Evolutionary effects
Reduced population density at larval level due to death of male embryos Selection for increased host clutch size
Failure of females to find mates where parasite prevalence leads to shortage of males, with potential effects on adult population size Selection for genes that prevent transmission or action of male-killer
Altered epidemiology of sexually transmitted pathogens due to increased reproductive success of males Alteration in host pattern of sexual selection due to alteration in population sex ratio
