    Abstract

    This experiment was aimed to observe adult population of fruitflies and its damage on chili planted in highland area (1100 m above sea level) and the potency of its parasitoids as well. Laboratory and field observation were carried out from December 2006 to March 2007. Three parameters of observation were the number of fruitflies trapped in modified Steiner traps, the severity of damage, and the infested chili fruits. Fruitflies trapped were determined once a week. B. dorsalis was fruitfly species found abundantly in farm with 14.70 adults per trap per 200 m2 on 18 week after planting (wap) chili. The severest percentage of damage was found 13.15% per 200 m2 when chili was 17 wap. Psyttalia fijiensis, Psyttalia incisi, Psyttalia fletcheri and Opius sp. were natural enemies that parasitized fruitfly in farm. The apparent parasitism rates for each parasitoid were 8.18%, 25.06%, 9.31% and 1.23% respectively. P. incisi could be suggested to be applied as potential parasitoid to control B. dorsalis.
