Effect of fabricated of indigenous fruit fly traps for control of fruit flies in mango and guava orchard and to identify effect of colour of traps on fruit flies

Experiment was carried out in Insectary (Dept. of Entomology), College of Home Science and guava orchard (Dept. of Horticulture) located at Chandra Shekhar Azad University of Agriculture and Technology, Kanpur (U.P) during 2017-18. There were 4 treatments were used for attraction of fruit flies. These treatments were green, yellow, transparent and Rakshak traps and methyl eugenol was used as attractant. The Bactrocera species which were attracted on coloured traps were Bactrocera dorsalis, B. correcta, B. zonata, B. nigrotibialis. The most predominant spp. attracted in guava orchard was B. zonata followed by B. dorsalis, B. nigrotibialis and B. correcta in all the traps tested. Out of four traps green trap was more attractive to all the Bactrocera species in Insectary (Dept. of Entomology) with a mean number of 66.25 fruit flies, in guava orchard (Dept. of Horticulture) 75.50 fruit flies and in College of Home Science 78.0 fruit flies.
