The experiments were conducted from April, 2010 to July, 2011 to explore the species richness of fruit fly and to observe the incidence of Bactrocera species by using Methyl Eugenol trap. In the first experiment, 11 species such as Bactrocera arecae, B. carambolae, B. dorsali, B. kandiensis, B. latilineola, B. malaysiensis, B. neocognata, B. raiensis, B. verbascifoliae, B. correcta and Carpomya pardalina were recorded. All species except Carpomya pardalina were observed in mango. Eight species in guava and five species in jujube were recorded. Bactrocera dorsalis was found to be the most abundant in mango and guava, and B. correcta in jujube. During the second experimental period, the experimental area can be recorded as an infested area because index of fruit fly population captured in traps, FTD (flies/trap/day), was seven. The highest population (437 flies/trap/week) was observed on May 26 in mango orchard. The number of fruit flies was observed to be significant positive correlation with weekly rainfall (R2 = 0.67 in mango, R2 = 0. 34 in guava and R2 = 0.43 in jujube) and relative humidity (R2 = 0.65 in mango), and negative correlation with mean temperature (R2 = 0.72 in mango) and sunshine hour (R2 = 0.61 in mango and R2 = 0.33 in jujube).
