The present study is carried out at Agriculture Research Institute Swat during the year 2018 to study the Integrating Management of fruit flies on Bitter gourd with indigenous plant extract i.e (Garlic extract and Neem extract) and a product chemical (Mythomyl) 90Sp. The experiment was randomized complete block design with replications. The chemical were applied three times at the rate of 3ml/litre of water. The lowest mean percent infestation and highest percent reduction in the population of fruit fly was recorded in plot treated with (Mythomyl) 90Sp was (1.36, 64.38), trailed by Neem oil extract (1.52, 58.29) and Garlic extract (1.57, 59.36) which were nonsignificant. While highest mean population of fruit fly was observed in control plot (3.76). The highest yield and lowest percent damage (1845kg/ha, 15.3%) was observed in plot treated with Mythomyl 90Sp. Which were followed by Neem oil extract (1610kg/ha, 35.3%) and Gralic extract (1345kg/ha, 55.5%). While lowest yield and highest percent damage (1112kg/ha, 75.5%) was observed in control plot. The highest CBR was recorded in plot treated with (Mythomyl) 90Sp 1:5.41 followed by Neem oil extract 1:4.64, while lowest CBR was observed in Garlic extract 1:3.64 respectively. So it is concluded that the Chemical insecticide (Mythomyl) showed best results as compared to botanical extracts in controlling against fruit flies infestation and in production of Bitter gourd. It is recommended that Chemical insecticide (Mythomyl) is superior for controlling against fruit fly.
