AB Androdioecy (the coexistence of males and hermaphrodites) is a raremating system for which the evolutionary dynamics are poorlyunderstood. Here, we investigate the cottony cushion scale, Icerya purchasi, one of only three reported cases of androdioecy ininsects. In this species, female-like hermaphrodites have been shown to produce sperm and self-fertilize. However, males areocassionally observed as well. In a large genetic analysis, we show for the first time that, although self-fertilization appears tobe the primary mode of reproduction, rare outbreeding events do occur in natural populations, supporting the hypothesis thathermaphrodites mate with males and hence androdioecy is the mating system of I. purchasi. Thus, this globally invasive pest insect appears to enjoy the colonization advantages of a selfing organism while also benefitting from periodic reintroduction of genetic variation through outbreeding with males.
