Abstract: Study on population magnitude of melon fruit fly, Bactrocera cucurbitae (Coq.) in watermelon was done during November 2018 to January 2019 in three districts of Tamil Nadu using cue-lure traps. The traps were arrayed at 45 cm height in the experimental sites. Significantly higher mean population was recorded in Dharmapuri (17.57±0.78) followed by Tiruvannamalai (16.14±0.79) and Kanchipuram districts (13.8 ±0.84). Irrespective of the location, highest mean population was found during December while lowest population was observed during last week of January. Negative correlation was obtained between temperature and fruit fly population, while rainfall and relative humidity positively correlated with fruit fly capture in all the three experimental sites. Higher population level observed during December month coincided with peak flowering period of watermelon crop. Results reveal that low temperature and availability of flower, influence population level and hence planting period can be manipulated to escape peak population period of fruit fly.
