Snake gourd, Trichosanthes anguina L., in the family of cucurbitaceae is the most important tropical and sub-tropical vegetable, which contains lots of medicinal properties that cure people from blood pressure, heart disease, rheumatism and psoriasis. Fruit flies (Tephritidae: Diptera) are polphagous pest and widely distributed in subtropical, tropical and temperate regions of the world. Melon fruit fly, Zeugodacus cucurbitae Coquillett is the serious pest of all cucurbitaceous vegetable and reduces the yield of a crop. Adult flies create oviposition punctures on the fruit rind and hatched maggots from the eggs feed on the pulp portion of the fruit. The maggot feeding leads to reduce the marketability and unfit for human consumption. The intensity of the infestation of fruit fly is closely related with the weather parameters and species diversity in the particular location. To overcome the yield losses, there is a need for monitoring of pest species in relation with meteorological factors which helps to determine the management practices. To assess the seasonal occurrence, fluctuation and its species diversity the field experiment was conducted at farmer’s field at Kumaravadi village, Tiruchirappalli during kharif and rabi season 2019-20. The fruit fly species of Z. cucurbitae, Z. gavisus and B. vishnu were trapped in cue lure baited traps and the species viz., B. dorsalis, B. zonata and B. correcta species were trapped in methyl eugenol traps and the species were taxonomically categorized. The maximum population was noticed and trapped in 35th Standard Meteorological Week (SMW) i.e., 25.80 fruit flies/trap in kharif and 10th SMW (12.3 fruit flies/trap) in rabi. On comparing the weather parameters relative humidity and rainfall shows negative correlation and other factors are positively correlated with the trap catches in both the seasons.
