概要
[Synopsis] We found large numbers of the exotic millipede, Chamberlinius hualienensis, which is originally distributed in Hualien, Taiwan, from two areas in Wakayama Prefecture. Because there was no trace of a large amount of soil or plants brought into the study sites, and the millipede was univoltine, these populations suggested their invasion was not recent in Wakayama Prefecture. The density of the millipede was 9.5±8.1 ind./m2 in the forest in Tanabe City. Its density was lower than observed when outbreaks occurred in Kanagawa and Okinawa Prefectures (1/6- 1/54 times). Therefore, it was considered that there was no outbreak of millipede at this site at this time. This is the first report showing the possibility of the millipede has invaded in the Kinki region in Central Japan.
