The mango fruit fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae) is a destructive polyphagous pest, posing threat to mango growers in Papparampakkam village of Tiruvallur District in Tamil Nadu. Population dynamics of fruit fly and yield were recorded in Papparampakkam village of Tiruvallur district during 2014-15. The results showed that trap catches was high, 839.1 fruit flies per trap during July 2014, followed by August, 2014 (563.8 fruit flies /trap). The fruit fly population was low during January, 2015 to April, 2015. Mango fruit yield was found to be high 143 q/ha in IPM plot due to the adoption of IPM strategy viz., field sanitation, soil raking and installation of methyl euginol fruit fly traps @ 25 /ha and in Non IPM plot the fruit yield was observed to be 112 q/ha. Benefit cost ratio was also found to be high in IPM plot (1:11.5) when compared to Non IPM plot. | Population dynamics and management of mango fruit fly Bactrocera Dorsalis (Hendel) (Diptera: Tephritidae)
