Abstract : The influence of biotic (host plant) and abiotic factors (weather parameters) on the abundance of fruit fly (Bactrocera dorsalis) on mango was studied in experiments conducted in Tirupati, Andhra Pradesh, India. Peak incidence of fruit fly activity was observed during the last week of May (6.9 infected fruits per 20 fruits). Correlation studies between incidence and weather parameters showed significant positive relationship with maximum and minimum temperatures and negatively correlated with rainfall and relative humidity (morning and evening). Older mango trees (15 years old and above) were more susceptible to fruit fly damage than young trees.
