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, have been tested to see whether they would provide an effective biological controller over the woolly adelgid. Members of Derodontidae ( L. erichsonii) have already been introduced into Canada in the 1950's to control the wooly aphid, a similar creature These tests included: no choice and paired choice feeding, oviposition (Oviposition is the process of laying eggs by oviparous animals.) wikipedia http://en.wikipedia.org/wiki/Oviposition accessed 3 november 2011, and develpment tests with the invasive species, three other adelgids, and three nonadelgids. When examining the results of these tests they suggest that  Laricobius osakensis actually may be an effective biological control agent for the woolly adelgid.
