Experiments were conducted to understand and collect data on select aspects of mango fruit fly, Bactrocera dorsalis like study of Eco-friendly Management by using different Insecticides/chemicals with some NonChemical methods, evaluation of various MATs and Baits for trapping of fruit flies, Population fluctuation of fruit flies infesting fruit crops in Hamirpur district during 2018-19. Among the various Male Annihilation Techniques evaluated against fruit fly, Methyl Eugenol (4ml) + Malathion (1ml) + Ethanol (6ml) septum size (8x2x1.8cm3) showed on an average highest catches (43.80/94.60/127.08 fruit flies/trap/week) in different months, and showed significant superiority over other treatments. Among the different coloured traps evaluated against fruit fly at Bhota and Jalari, yellow trap (764.62/1555.50 fruit flies/trap) showed significant superiority over other traps except green trap (507.87/1364.37 fruit flies/trap) which was at par with yellow trap. On an average the population of fruit flies was more at Jalari Farm than Bhota Farm. Among different baits evaluated against Mango fruit fly, BAT 4 i.e. Casein + Sugar + Banana pulp (25.44 fruit flies/trap) recorded maximum number of fruit flies and was found significantly superior over other traps. Lambda cyhalothrin (0.004%) is significantly superior (8.33% infestation) compared to all other insecticides, followed by Chlorantraniliprole (0.005%), Cyantraniliprole (0.002%), Spinosad (0.004%) and Deltamethrin (0.0028%), Neem (0.002%), Cypermethrin (0.0075% ), and Malathion (0.1% + 1% sugar) showed 10.67, 12.00, 12.33, 14.00, 19.00, 21.00, 21.67 per cent infestation, respectively.
