(Executive Order 13112). Quarantines, though established, have not prevented the entrance, establishment and spread of invasive species of insects. Identification of stages, their biology, natural enemies, insecticide control and management practices have been studied. However, these pests have become established. Dr. Kenneth A. Sorensen Extension Entomologist N . C. State University Raleigh, N. C. 27695-7626 kenneth_sorensen@ncsu.edu Past introductions & outbreaks of these introduced pests offer hope for dealing with future pests & better understanding their pathways of entry, their monitoring & movement, their natural enemies, & their control & management.
