Abstract : Studies were conducted to investigate the efficacy of insecticidal application and pheromone traps against fruit flies on mango. Experiments were laid out in the orchards of University of Agriculture, Faisalabad, Punjab, Pakistan. The orchards were treated with Diptrex 80 SP (trichlorophon [trichlorfon]) from May to August 1997, once a month, along with 2, 4, and 6 pheromone traps/ha. It was found that 4 pheromone (methyl eugenol) traps were best for controlling fruit flies with minimum damage of 1.5% and 4.15% in July and August, respectively. The investigations on seasonal activity showed that the population of Dacus zonatus [Bactrocera zonata] was higher than that of Dacus dorsalis [Bactrocera dorsalis] throughout the activity season in 1997. The highest male population of Dacus spp. was observed in first week of July. Fourteen days interval application was found to be more effective than monthly applications.
