イネカメムシ（カメムシ目：カメムシ科）越冬成虫の飼育条件下での生存日数と産卵能力

抄録

The rice stink bug, Niphe elongata (Dallas) (Hemiptera: Pentatomidae), is a pest that siphons the nutrients from developing rice grains. In this study, the longevity and fecundity of overwintering adults collected at a hibernation site on February 15 and 16, 2021, were examined at 25°C under a photoperiod of 16L:8D. Females started mating 46 days later and laid eggs 60 days after rearing began. The mating and ovipositional start times of the females were later than those of other stink bugs that hibernated in their adult stages. This is thought to be related to the difference in active time among adults who finished overwintering. The mean longevity was 103.8 days for females and 99.1 days for males. The mean number of eggs per egg mass was 12.1. On average, each female laid 88.1 eggs under laboratory conditions.
