Commercially Aonla (Emblica officinalis) cultivation is increasing due to its great nutritional and medicinal value accompanied by the release of high yielding varieties. It is being grown mainly in agroforestry systems in this region. Virachola isocrates, which was a minor pest earlier, has now attained a major pest status on Aonla resulting in the damage to the extent of 38%. The present study revealed that NA 6 (16.04%) and Chakaiya (19.37%) were less susceptible than NA 7 (22.60%) and Kanchan (37.89%). High temperature and low relative humidity along with the pest behaviour favoured the multiplication of this pest.
