Rg. Booth, A REVIEW OF THE SPECIES RESEMBLING CHILOCORUS-NIGRITA (COLEOPTERA, COCCINELLIDAE) - POTENTIAL AGENTS FOR BIOLOGICAL-CONTROL, Bulletin of entomological research, 88(4), 1998, pp. 361-367
Chilocorus nigrita (Fabricius) is a well-known predator of scale insec
ts. It has been widely used for biological control and has spread natu
rally beyond its previous native range over the last three decades or
so. Three other Oriental species closely resembling C, nigrita can now
be separated. Chilocorus melas Weise is redescribed and a lectotype d
esignated. Chilocorus gressitti Miyatake is a junior synonym of C. mel
as. Chilocorus subindicus from the southern parts of the Indian subcon
tinent and C, gracilior from eastern Indonesia are described as new.
