Hawaii Department of Agriculture

The Plant Pest Control Branch (formerly Entomology Branch) of the Hawaii Department of Agriculture has maintained a beneficial organism introduction program for many years. This paper provides notes on the status of some pests and their purposely introduced natural enemies and a list of insects introduced and released for biological control during 1979 and 1980. All beneficial introductions are thoroughly screened and studied in a quarantine facility and must go through a clearance process prior to being released.
