| Abstract:
A trapping programme was carried out for fruit flies for 13 months on the island of Mahe, Seychelles. Only the Mediterranean fruit fly was present. Several variations of plastic 'sandwich container' trap were compared and the one found most suitable and efficient contained the attractant trimedlure and a block of insecticide (DDVP) - impregnated resin. Fruit flies were found in all eight places where trapping was carried out. Most fruit fly activity began in April and normally declined by August or September; they were most abundant in areas where citrus was grown and less abundant where only vegetable crops were present irrespective of whether traps were placed at sea level or at higher elevations. | |
