abstract
Mango is affected by various gall midge species on leaves, fruits, buds and inflorescence. Gall midge on the twigs and branches of mango was recorded for the first time in Karnataka. A survey was conducted to know the incidence, severity and varietal preference of the branch gall midge in major mango regions viz., Dharwad and Belgaum. Incidence and severity of this pest ranged from 12.34 to 97.22 and 4.2 to 25.19%, respectively. The Alphonso variety recorded the highest incidence and it was lowest in Mallika variety among the mango varieties screened during survey. Feeding by the midge induces gall like structures on the branches and will also affect translocation system of the affected part which ultimately results into drying of the affected branches from tips and will not produce inflorescence. The emerged adults from the gall was sent for identification and identified as Procontarinia sp. Looking to the nature of damage and parts get affected on mango tree, the pest is considered as a potential threat to mango cultivation and needs immediate attention.
