Abstract : The management of B. dorsalis and B. zonata in guava and mango orchards by poison baits (T1), mass killing of winter-congregated population (T2) and insecticide application (T3) was evaluated in Entkhedi, Madhya Pradesh, India, during 2001-03. Among the treatments, mass killing of winter-congregated population was the most economical and effective. Fruit infestation in guava and mango orchards reached 4.661±2.44 and 5.337±3.644% under T1, 3.416±1.824 and 2.425±1.663% under T2, and 12.377±8.224 and 14.325±10.235% under T3, respectively. Fruit flies showed congregation behaviour when the weekly minimum temperature was more than 14°C. A positive significant correlation between congregation behaviour and minimum temperature was recorded (r=0.2916, 0.3624). Sex ratio (male:female) and species ratio per congregated mass were 1:0.85, 1:0.83 and 1:1.45, respectively.
