Abstract

The black markings on larvae of Cactoblastis spp. can be used to separate different biotypes or species. These markings are figured, together with host and locality records for ten distinct biotypes or species, at least five of which are undescribed. Past introductions of C. cactorum (Berg) and Cactoblastis spp. to Australia and elsewhere are reviewed, and it is suggested that some of the undescribed biotypes might be of value in the biological control of Opuntia spp.
