The cucurbit fruit fly is a highly damaging pest of almost all the cucurbit vegetables. Indiscriminate use of pesticides by the farmers to control the pest has endangered the safety of the environment and increased the chances of accumulation of poisonous residues in the produce. This project investigated how mass-trapping of fruitflies through pheromone and other bait traps will reduce fruit fly population,minimize the use of pesticides and help establish a safe control measure for the production of pesticide-free cucurbit crops.
1. To determine the preference of the cucurbit fruit fly for some major vegetable crops 2. To reduce the infestation of fruit fly and establish an environmentally safe control measure in cucurbit crops by using pheromone and indigenous bait traps.
Bitter gourd was the most preferred host of the cucurbit fruit fly, followed by sweet gourd, ash gourd and cucumber. Fruit fly infestations started from the time of fruit initiation and continued as long as the crops produced fruits. Mass trapping with MSG and cuelure baits was highly effective to reduce fruit fly infestations and produce high yields.
