Across the globe, it is widely observed that current change in climate or 
weather pattern has marked effect on insect population dynamics and 
behavior, though with varied aspects and intensity. The study revealed that the population was highest 
during the fruit development and ripening stageand it was found that the 
number of flies per trap and meteorological parameters (temperature and 
humidity) is positively correlated with appreciable statistical significance.The current study aims to determine 
how changes in weather parameters influence the population dynamics 
of fruit flies and to develop an optimized weather-based population prediction 
model for fruit flies infesting citrus in the mid-hills of Arunachal Pradesh.
