Evolution of Male-Killer Suppression in a Natural Population
Male-killing bacteria are widespread in arthropods, and can profoundly alter the reproductive biology of their host species. Here we detail the first case of complete suppression of a male killer. The nymphalid butterfly Hypolimnas bolina is infected with a strain of the bacterium Wolbachia, wBol1, which kills male host embryos in Polynesian populations, but does not do so in many areas of Sout...
متن کاملA Nightmare for Males? A Maternally Transmitted Male-Killing Bacterium and Strong Female Bias in a Green Lacewing Population
For maternally transmitted microbes, a female-biased host sex ratio is of reproductive advantage. Here we found a strong female bias in a field population of the green lacewing, Mallada desjardinsi (Insecta; Neuroptera). This bias was attributed to the predominance of individuals harboring a maternally inherited male-killing bacterium that was phylogenetically closely related to the plant-patho...
متن کاملEvolutionary Conflicts: Rapid Suppression of a Male-Killer
Conflicts between and within species can drive fast evolutionary change. A recent study has documented remarkably rapid counter-adaptations in the wild to an extreme sex-ratio distortion caused by a bacterial symbiont.
