Description

The head width of hidernating cockroaches, Asiablatta kyotoensis Asahina, in an unheated room divided nymphs into two groups, young nymphs (2nd-4th instars) and older nymphs (7th-8th or final instars and excessively molted instars). The older nymphs emerged into adults in early summer, producing several oothecae before dying in fall. The younger nymphs overwintered again in older stages. New nymphs hatching before mid-summer developed into final or penultimate instar stage before overwintering, while those hatching in fall overwintered in 2nd-4th instars. The formation of two phases in hibernating nymphs indicates the existence of timing mechanisms such as diapause.
