斑点瓢虫是一种广为人知的捕食性瓢虫，分布于欧洲、中亚和北美。本种在日本没有被记录。最近，我们在日本中部的大阪湾地区发现了这种物种，并假设它是随木材等货物通过轮船进口的。我们研究了大阪湾地区自发现以来的生活史和分布。幼虫和成虫捕食树上的蚜虫(主要是绿色Periphy llus viridis)。越冬的成虫在3月份出现并产卵。成虫在春天出现，一年中剩下的时间都在卷着的树叶里。因此，在日本，这种瓢虫是一成虫，成虫长期不活动。日本二斑潜蝇种群的生活史与其他种群多变的地区有很大的不同。从卵到成虫羽化的发育起点温度为6.3C，有效温度总和为322.6日度。有时还观察到异色瓢虫等本地种幼虫对二斑潜蝇预蛹的捕食作用。
Adalia bipunctata is a well-known predaceous ladybird distributed in Europe, Central Asia and North America. This species has not been recorded in Japan. Recently, we found this species in the Osaka Bay area in central Japan, and assume that it was imported with goods such as timber by ships. We studied the life history and the distribution in the Osaka Bay area since the initial discovery. The larvae and adults preyed on aphids (mainly, Periphyllus viridis) on trees such as Acer buergerianum and Rhaphiolepis umbellata. The over-wintered adults appeared in March and laid eggs. The adults emerged in spring, and were in the rolled leaves throughout the rest of the year. Thus, in Japan this ladybird is univoltine with long inactivity in adult. The life history of Japanese population of A. bipunctata differs considerably from other areas where populations are multivoltine. The developmental threshold was estimated to be 6.3°C and the sum of effective temperatures was 322.6 day-degrees for the period from egg to adult emergence. Predation on prepupae of A. bipunctata by the larvae of native species such as Harmonia axyridis was observed occasionally.
