Abstract

Biological control has been a major focus of efforts to reduce the impact of hemlock woolly adelgid (HWA) on hemlocks in the eastern United States. The lady beetle Scymnus sinuanodulus Yu et Yao, one of the most abundant predators of HWA in China, was first imported in 1996. Subsequently its biology and host range were evaluated in quarantine and limited numbers are now available for field release.
