Notes: San Jose scale Quadraspidiotus perniciosus is a key pest of apple crop in the northern states of India. An assessment on its population density was carried out in five districts of Kashmir Valley. The efficacy of entomopathogenic fungi–Beauveria bassiana, Metarhizium anisopliae sensu lato and Lecanicillium lecanii at three concentrations against the pest was examined in an experimental orchard. High mortality (77%) was determined with B. bassiana at 15 × 105 conidia /ml. concentration followed by L. lecanii at the same concentration (mortality 75%). However, M. anisopliae sensu lato was significantly less effective (mortality 53–68%) among the three concentrations tested during field trial. The results demonstrate the suitability of entomopathogenic fungi for controlling San Jose scale.
