Stem Borer (Batocera rufomaculata) is widely distributed in India and attack a number of fruit trees including mango. The grub of this pest feeds inside the stem, making tunnel upward which results in drying of branches and in severe cases death of tree. Eggs are laid either in the cracks of tree trunk or in the cavities of main branches which covered with viscous fluid. Grub pupates inside the stem and beetle emerges in July/August.
