Abstract
Chlorophorus annularis Fab. is a primary borer of cut and dry bamboo. Adult Cerambycid beetles emerge in May-September mainly in June. The female of C. annularis laid eggs on cut bamboo that is fairly dry during May-July. Freshly laid egg is elliptical in shape and off-white in colour and later changed to yellowish white. Single gravid female lays 21.6 ± 2.59 eggs. The incubation period is 12.9 ± 1.46 days. Larvae of C. annularis are milky white and on hatching, bore into the tissues of the walls of the bamboo and larval period extended for 9-10 months. Pupa is off-white in colour and later changes to yellowish white. The pupal period is about one month during March-April. Total life cycle from egg hatching to adult beetle emergence was spread over one year.
