Nutritional status of overwintering adults of the brown marmorated stink bug, Halyomorpha halys (Hemiptera: Pentatomidae), is affected by cone counts of Japanese cedar, Cryptomeria japonica, in northern Japan

摘要: Although researchers have proposed that the abundance of Japanese cedar cones is main factor affecting outbreaks brown marmorated stink bug, Halyomorpha halys (Stal), in Japan, it remains to be clarified whether reproduction field populations indeed influenced by variation number cones. This study investigated relationship nutritional status overwintering adults with airborne pollen count cedar, which served as a proxy for cone-bearing cedars, based on data gathered from 2000 2010 Akita Prefecture, northern Japan. The level and counts varied significantly over 11 years considered. There was significant correlation between each sex. These results suggest serve an important source H. they prepare overwintering.
