Abstract: The objectives of this newly funded Forest Service activity are to promote the biological control of hemlock woolly adelgid (Adelges tsugae Annand) by (1) hiring an entomologist to work in Asia; (2) revisit known collecting sites and find promising new ones; (3) study the life history and phenology of HWA and its predators; (4) establish protocols for estimating the host ranges of candidate biological agents for use against HWA; (5) enhance quarantine facility capacity; and (6) ship more natural enemies (more species, more individuals) to U.S. quarantine. Initial work is focused in central China (Shaanxi, Sichuan and Yunnan Provinces) and central Japan. An entomologist trained in America, Wenhua Lu, has been contracted to work overseas in China. Additionally, agreements have been made with experts in each country to conduct and assist with field research in China and in Japan. This project builds on previous collecting and study of HWA natural enemies by Mike Montgomery, Scott Salom, and previous cooperators in China.
