The Hemlock Woolly Adelgid is an invasive pest within the eastern United States. Laricobius osakensis Montgomery and Shiyake, both proud members of the family Derodontidae, are being tested to see whether they will prove to be an effective control agent of the Hemlock Woolly Adelgid. <ref>G M G Zilahi-Balogh, L M Humble, L T Kok, S M Salom.
