PROJECT: Detection and Eradication of Arthropod Pests of Quarantine Importance in the Northern Territory Project Officers: All Branch Officers Location: Territory wide Objective: To detect, identify and assess the feasibility of eradicating or controlling arthropod species of quarantine significance, which are new to the NT. Background: When previously unrecorded species in the NT have penetrated the Quarantine barrier, one of the responsibilities of the Entomology Branch is to detect, identify and assess the feasibility of eradicating or controlling them. The civil unrest in the former Indonesian province of East Timor and the subsequent large military and civilian involvement of Australian and other personnel created a significant increase in the potential for exotic organisms to enter the Darwin area. Surveys were conducted of high-risk areas in Darwin to detect potential quarantine pests and diseases originating in East Timor. Results: Following the detection and subsequent successful eradication program mounted against the Asian honeybee Apis cerana Fabricius (Hymenoptera: Apidae) from June 1998 to June 1999, samples of feral honeybees continued to be submitted for testing during 2000/2001. Asian honeybees were not discovered, nor were mites detected on any of the A. mellifera examined. The port surveillance program, which was initiated by the Animal Health Branch, continued to monitor artificial coconut traps and sentinel and feral honeybee hives. The Entomology Branch conducted all testing for bee and parasitic mite species. Several other species were assessed for their quarantine importance and official notification made on detections during consultative committee teleconferences. These included the fig wax scale Ceroplastes rusci (Linnaeus) (Hemiptera: Coccidae) on mango in both Darwin and Katherine and a species very similar to the Indian cotton leafhopper Amrasca devastans (Distant) (Hemiptera: Cicadellidae). The former had
