Male-Killing Bacteria in Insects: Mechanisms, Incidence, and Implications
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 |
