Abstract:
The present studies on the “Impact of weather parameters on population dynamics of fruit fly (Bactrocera spp.) in cucurbits at different locations” were conducted in the Department of Entomology, Acharya Narendra Deva University of Agriculture & Technology, Kumarganj, Ayodhya, during 2020-21. Significant variation in the occurrence of the fruit fly was recorded during the period of investigation. Trapping of fruit fly was started from the 9^th SMW and continued up to 25^th SMW by using sex attractant, Cuelure and methyl eugenol. Incidence of B. zonata and B. dorsalis, was observed high (48.75 fruit flies/trap/week) and (38.41 fruit flies/trap/week) respectively on 21^st SMW caught by methyl eugenol. And the Incidence of B. cucurbitae and B. tau, was observed high (33.41 fruit flies/trap/week) and (18.00 fruit flies/trap/week) respectively on 20^th SMW caught through cue lure. Mean population of B. zonata, B. dorsalis showed highly significant positive correlation with minimum temperature and maximum temperature, while the relative humidity showed significantly with negative correlation and rainfall showed non-significantly negative correlation respectively and B. cucurbitae, B. tau population showed non-significantly positive correlation with minimum temperature and significantly positive correlation with maximum temperature however it was significantly negatively correlated with relative humidity and non-significantly negative correlated with rainfall respectively in Zaid season of 2020.
