Abstract

A preliminary study of fruit flies was conducted at five islands within Tunku Abdul Rahman National Park (TARP) from February 2014 to April 2014. The objectives were to investigate the diversity of fruit flies (Diptera: Tephritidae) and to construct a set of pictorial identification key for species found at TARP. Three methods were applied: Bait trapping with parapheromones Methel Eugenol (ME) and Cue lure (CUE), manual collection and the Malaise trap. The bait traps and Malaise trap serviced for three days in each island. A total of 37 fruit fly species was obtained, 33 of them from the genus Badrocera and another four belong to other genera, namely Trupanae, Euphranta, Adrama, and Dacus. The most abundance species is the Badrocera albistrigata (50.36%), following by the B.papayae (13.89%), and B.carambolae (10.71%). The fruit fly diversity of TARP was found high with the highest Shannon Diversity Index (H'=2.19) shown from Gaya Island. From the collection, 20 Badrocera species were assigned to morphospecies due to the lack of identification material. A pictorial dichotomous key of generic level and species level were constructed. This first TARP fruit fly key is important to provide general identification guide of fruit flies at TARP. The key could be further upgraded to the key of fruit fly identification in Borneo as more studies going on.
