Incidence of borers on Terminalia arjuna W. & A. and their control in Osmanabad, Marathwada region

ABSTRACT Terminalia arjuna W. & A. is an important food plant for rearing Antheraca mylitta Drury for wild silk production. T. arjuna is attacked by three borers viz., Aeolesthes holocericea Fab., Sphenoptera cupriventris Kerr. and Inderbela quadrinotata (Walk.). I. quadrinotata lay eggs on the crop plant in February-March while, other species lay in May-June. Grubs cause death of side branches later the entire plant by boring. The above borers were controlled by using chloropyriphos 20% EC 0.05%, 0.1%, dichlorvos 76% EC .75%, .15% and Azadirachtin 10000 EC 0.05%, 0.1%. Sealing bored holes with petroleum oil and mud, killing pests in bored holes with iron hooks and collecting larvae as early in the morning from bored frass helped controlling the pest species.
