Rhyzobius
Rhyzobius is a genus of small lady beetles (Coccinellidae) in the tribe Coccidulini. The genus was established by J.F. Stephens in 1829 (published 1832) and contains approximately 106 recognized species worldwide. Members are specialized predators of scale insects (Coccoidea), particularly armored scales (Diaspididae). Several species, notably R. lophanthae and R. ventralis, have been widely introduced as biological control agents against scale pests in temperate regions globally.
