The field experiment was conducted during 2013-16 at Navsari Agricultural University, Paria, Gujarat to study the role of weather parameters on population dynamics of oriental fruit fly, Bactrocera dorsalis on mango, Mangifera indica L. Fruit flies were recorded throughout the investigation period, wherein maximum catches were observed during April - July which coincided with fruiting and harvesting stages of the crop. Weather parameters viz., minimum temperature, evening relative humidity, rainfall and wind velocity were found to be important predictors of fruit fly catches, while maximum temperature and morning relative humidity failed to establish significant correlation with the catches. The optimized model developed using rainfall and wind velocity predicted fruit fly catches based on R2 value to the tune of 78 per cent. This forewarning model may help mango farmers to take advance decision for minimizing the quantitative and qualitative crop losses caused by fruit flies of the region.
