    Description

    This chapter reports on predators which have only preliminary information or were found to have a host range that was too broad to be considered as safe biological control agents. The predators reviewed here include predaceous anthocorid bugs from China and western North America, a Laricobius beetle from China, and a lady beetle native to western North America. For each of the species, information on their taxonomy, biology, and host range is provided and their potential as a biological control agent for Adelges tsugae Annand, the hemlock woolly adelgid (HWA), is evaluated. Key questions for the reader to ponder are how host specific should HWA predators be and can successful biological control be achieved using only predators that are specific only to HWA.
