abstract
Fruit flies constitute the most important group of pest infesting fruits and cucurbitaceous vegetable crops throughout the universe. Particularly Melon fruit fly has been weighed notorious pest. For the management of this pest, various control measures have been advocated in all over the world. During the performed research work assess the Persistency and Durability of cue-lure sex pheromone and of three different insecticides including Limda, Amida, and Route. Keeping in view sex pheromone was used for the attraction as well trapping of flies under laboratory conditions and the insecticides mixed with cue-lure for the killing of pest inside the traps was observed as triplicate under field conditions. The four different persistency durations such as 15, 25, 35, 45 days were observed in bitter gourd crop. Results revealed that significant higher Bactrocera cucurbitae were captured in the fifteen days of replenished which (41.89±1.83a). However, significantly lower (19.44±1.46e) after sixty days of replenished. It was observed that lure might be replenished after every fortnight in the month of May, June and July-2016. Moreover, results also depicted that considerably higher (49.62±1.95) killing of Bactrocera cucurbitae were observed in route and lower (38.30±1.92) in Amida. The results of the study would be helpful for the selecting of the insecticide in mixing with cue-lure for the management of the cucurbit flies under field conditions.
