ABSTRACT Diversity of Fruit Flies and Parasitization Level of Parasitoid Associated with Plants Fruits in Lautem District, Timor Leste. Research on diversity of fruit flies and parasitization level of parasitoid associated with Plants Fruit was done from November 19, 2014 up to Februari 2, 2015 in Lautem district, Timor Leste. The objectives of this research are to determine of diversity of fruit flies, percentage of damage, and parasitization level of parasitoid associated with fruits tree in Lautem District. The research using survey method and traps made from plastic bottle filled chemical atraktan form Methyl eugenol, Cue-lure, and Dorsal lure installed in five sub District in Lautem District. The purpose of survey methods were to account percentage of damage fruit and parasitization level of parasitoids, while istaled traps aimed to know diversity of fruit plies, dominance, and similarity index.
