Abstract

<p>Asian multicolored ladybird, Harmonia axyridis, has been found in Ishigaki island and Okinawa island recently as an invasive species in Ryukyu Islands. Harmonia yedoensis is originally distributed in these areas, suggesting that competitive interactions may affect on native community. Here we examined niche use of H. yedoensis in Ryukyu Islands and tried to detect H. axyridis. Moreover, we performed genetic analysis when we cannot identify species by morphology. We found that H. yedoensis uses a variety of habitat in Ryukyu Islands, including fig trees. In addition, we detected H. axyridis from Ishigaki island collected in 2015. We need to develop a cost-effective method to identify these species to detect H. axyridis in its invasive region.</p>
