Field studies were conducted in guava orchard near NIA experimental farm, Tandojam to evaluate an efficient trap height and optimum time for trapping the fruit flies as an important component of pest management. To determine appropriate trap height, lure toxicant traps were hung at the height of 2, 4, 6, 8 and 10 feet from ground level and adult flies captured were counted weekly. Similarly, to note diurnal activity of flies, five traps were hung at 10 feet height at 5.00 h and data was recorded after each 2 upto 19.00 h. It was noted that significantly highest number of flies were captured in the traps hung at 10 feet height and maximum population was recorded during 5-7 h.
