| dc.description.abstract | As many as 24 species of insect pests were recorded on bitter gourd, of which twelve species were defoliators, eight species were sucking pests, one was a gall former and three species were fruit borers. Among the pests, Bactrocera cucurbitae caused serious damage during kharif season, where fruit infestation ranged from 30 to 52 per cent, which was significantly and positively correlated with rainfall (r = 0.71*) and positively correlated with maximum relative humidity (r = 0.59). During rabi, fruit fly infestation ranged from 26 to 33 per cent which was significantly and positively correlated with maximum temperature (r = 0.76*). Studies on monitoring of fruit fly with para-pheromone trap revealed that maximum trap catches, (on an average 129 to 162 flies/trap/week) were recorded between September – October 2014 and minimum trap catches (on an average 6 flies/trap/week) were recorded in January 2015. The trap catches were significantly and positively correlated with rainfall (r = 0.73*) and minimum temperature (r = 0.65*) and positively correlated with maximum temperature (r = 0.13), maximum relative humidity (r = 0.30), minimum relative humidity (r = 0.17) and wind speed (r = 0.28). Efficacy of selected insecticides against melon fruit fly revealed that the combination of jaggery @ 0.015 per cent with deltamethrin @ 0.0028 per cent showed significantly lowest fruit infestation and maggot population per infested fruit as compared to other treatments. The fruit yield was significantly also higher in this when compared to the remaining treatments. | en_US |
