Abstract

Nutritional status of post-overwintering adults of Halyomorpha halys at their hibernating site was investigated in Akita Prefecture, northern Japan from 2000 to 2005. Nutritional levels of the adults were significantly lower than those of pre-hibernating adults, and the fat body did not develop. Additionally, nutritional levels of the adults recently exited from the hibernating site were significantly lower than those of the adults at their hibernating site in April in 2001 and 2002. Almost all the adults given only water in field from late April could not survive until late May in 2002. These observations suggested that post-overwintering adults of H. halys exiting from the hibernating sites cannot survive for a long period, if they cannot feed on their suitable food plant.
