S. B. JAGGINAVAR, L. KRISHNA NAIK

Abstract


The Pomegranate (Punica granatum L.) was  recorded as a new host of shot hole borer,  Xyleborus perforans (Wollastan) in Maharashtra  (Mote, 1991). It's biology and life cycle have  been described by Danthanarayan (1973) on tea.  Adult female makes deep galleries inside the stem,  which hinders the translocation of nutrients and  water. The damage caused by shot hole borers  were of secondary importance like die back,  according to Beeson (I930). Since, last decade,  the pest is severe on pomegranate damaging main  trunk and branches (Mote and Tambe 1991) in  Maharashtra and Andhra Pradesh. Of late, in  Karnataka (Krishna Naik and Nandihalli, 1996)  it is appearing in serious proportions.
