In the process, they defend the scale from predators. The Vedalia beetle is native to Australia, but now has a world wide distribution due to its widespread use in classical biological control operations against (primarily) the cottony cushion scale (Icerya purchasi). Biological Control The regulation of I. purchasi by natural enemies is one of the classic … Classical biological control in practice. ", "Biological control of the cottony cushion scale, Icerya purchasi, on ornamental plants in Israel. According to the spatial density—dependence hypothesis, successful biological control is stabilized by parasitoid foraging behavior, such that increasing rates of parasitism accompany increasing local host (pest) density.
