Cucurbits suffer yield loss due to insect pest and diseases and the farmers incur more than 25 - 30% of the cultivation expenses towards the plant protection in Dharmapuri district. Front line demonstrations (FLD) were conducted in bitter gourd and ridge gourd to demonstrate the integrated pest management components viz., seed treatment, application of neem cake, installation of sticky and fruitfly traps, periodical removal of infested fruits and need application of insecticides. The percent incidence of fruitfly in demonstration was 8.90 in bitter gourd and 15.37 in ridge gourd whereas in farmers practice the percent incidence was 23.35and 32.12. The integrated management practices in bitter gourd recorded 26.4% yield increase during 2015 -16 and 17.17% yield increase in ridge gourd. The IPM module recorded benefit cost ratio of 3.40 in bitter gourd and 2.70 in ridge gourd and 2.09 and 2.2 in farmers practice. The lower yield, decreased returns and higher plant protection cost in farmers practice shows the non adoption of integrated pest management practices. The technology gap was 194q/ha for bitter gourd 106 q/ha in ridge gourd. The technology index for the present IPM demonstration for bitter gourd was 37.36 and for ridge gourd was 35.33. The lower technology index reveals the feasibility of demonstrated technology and sustained efforts required to disseminate among farmers
