KEANEKARAGAMAN DAN KELIMPAHAN LALAT BUAH (DIPTERA: TEPHRITIDAE) PADA BEBERAPA SISTEM PENGGUNAAN LAHAN DI BUKIT RIGIS, SUMBERJAYA, LAMPUNG BARAT

Diversity and abundance of fruit flies (Diptera: Tephtritidae) in a range of land use systems in Sumberjaya, West Lampung. Fruit fly inventory from seven land use systems in Sumberjaya area, West Lampung, using fruit incubation and lure trap methods resulted in four species of fruit flies, i.e. Bactrocera (Bactrocera) dorsalis, B. (B.) umbrosa, B. (Zeugodacus) cucurbitae, dan B. (Afrodacus) furvus. B. dorsalis was the most common fruit flies in the area while the least found was B. (A) furvus. The abundance of fruit flies was positively correlated with the weight of cempedak fruit (Artocarpus polyphema, Moraceae) and of the watery roseapple fruit (Syzygium aqueum, Myrtaceae).
