A multi-year dormancy strategy in a cabbage beetle population in southeastern China

The seasonal life cycle of the cabbage beetle Colaphellus bowringi in southeastern China is very complicated because there are four options for adult development: summer diapause, winter diapause, prolonged diapsuse, and nondiapause. However, detailed information on the multi-year emergence patterns of diapausing individuals in this beetle has not been documented. In this study, we monitor the adult emergence patterns of diapausing individuals and estimate the influence of the diapause-inducing temperature and photoperiod on the incidence of prolonged diapause under seminatural conditions for several years. The duration of diapause for adults collected from the vegetable fields in different years varied from several months to 5 years. Approximately 25.9-29.2% of individuals showed prolonged diapause (emergence more than 1 year after entering diapause) over the five years of observation. Furthermore, regardless of insect age, emergence always occurred in spring, between mid-February and ..., , , # A multi-year dormancy strategy in a cabbage beetle population in southeastern China
