Bactrocera papayae and B. tryoni trapped in New Zealand
On 1996-03-29, a single male Bactrocera papayae (EPPO A1 quarantine pest) was trapped in Auckland in the North Island of New Zealand. In the Auckland area, 326 methyl eugenol surveillance traps are placed at approximately 1200 m intervals. New Zealand has set up an ongoing fruit fly surveillance programme, in which traps are inspected every 14 days. All these traps were inspected during this period of two weeks, and no other fruit fly was found.
On the same date, two single male Bactrocera tryoni (EPPO A1 quarantine pest) were caught on cuelure traps, on the North Shore in Auckland. In this area, 1992 traps are placed at approximately 400 m intervals. As for B. papayae, these traps are regularly inspected and during the following two weeks period, no other fruit fly was found. As a result of these captures, further traps were placed in the vicinity of the capture points (within a radius of 1.5 km), and surveys on fruit were carried out. Mature fruit of many species have been inspected and no larval population were detected.
