Monitoring and relationship between trap catches of Bactrocera species revealed occurrence of B. dorsalis, B. zonata, and B. correcta and weather parameters such as rainfall, temperature, average relative humidity throughout the eight months. In horticulture orchard, peak catches of B. zonata was observered on second week of October 2006 and second week of March 2007 with the trap catch of 32.3 fruit flies/trap/week. B. correcta peak catch was observed on second week of December 2006 and second week of April 2007 with the trap catch of 30 and 47.6 fruit flies/trap/week. B. dorsalis peak catch was recorded, mean catch 2 fruit flies/trap/week in 2006, and 2007 peak catch was 46.6 fruit flies/trap/week during fourth week of April. In Vegetable farm. B zonata had peak catch on first week of October 2006 with 26.3 fruit flies/trap/week and gradually decrease with 24.3 fruit flies/trap in fourth week of January. B. correcta had peak catch was observed second week of December 2006 with 26.6 fruit flies/trap/week and fourth of April 2007 with 37.6 fruit flies/trap/week. B. dorsalis recorded normally in 2006 with minimum of 1.6 fruit flies/trap and in first week of April 2007 with 37.3 fruit flies/trap/week. In both the places, B dorsalis trap cathes had positively correlated with temperature and negatively correlated with rainfall and relative humidity.
