Host specificity and aspects of the biology of Coelocephalapion aculeatum (Coleoptera: Apionidae), a potential biological control agent of Mimosa pigra (Mimosaceae)
Environmental Entomology 23 (1), 147-153
Abstract: The biology of the weevil Coelocephalapion aculeatum (Fall) and its specificity to Mimosa pigra L. (Mimosaceae), a serious introduced weed in Australia and Thailand, were studied in a quarantine facility in Australia. Ninety-two plant species were screened, and M. pigra was the only host that sustained a population of C. aculeatum. Adults fed on developing and open inflorescences and oviposited mainly in buds of inflorescences of mid-to-late development. Larvae developed and pupated within these buds. Developmental time from egg to adult was 10-12 d. Field releases commenced in July 1991 in Thailand and in January 1992 in the Northern Territory of Australia.
