Description: Movements of 55 Anoplophora glabripennis (Motschulsky) adults were monitored on 200 willow trees, Salix babylonica L., at a site appx. 80 km southeast of Beijing, China, for 9-14 d in an individual mark-recapture study using harmonic radar. The average movement distance was appx. 14 m, with many beetles not moving at all and others moving >90 m. The rate of movement averaged almost 3 m per day. Movement patterns differed strikingly between the sexes: males averaged >6 times the total movement distance of females at appx. 2 times their rate. The overall recapture rate in this short-term experiment was 78%, but the radar tags attached to individual beetles often broke or otherwise were rendered undetectable after several days in the field. Currently, the harmonic radar system is useful for tracking beetles and obtaining estimates of their movement rates over short time periods. It will become useful for longer-term studies as more durable tags are developed.
