Resumen
Descripción
Purified spores of Beauveria bassiana (Bal.) and Beauveria tenella (Del.) were tested for pathogenecity against larvae of the Meliaceous shootborer Hypsipyla grandella Zeller reared on a synthetic diet. Larvae immersed for one minute in a suspension of spores showed a mortality of 13.9 per cent with B. bassiana at a concentration of 1.4 x 10 6 viable spores/ml and 12.7 per cent with B. tenella at a concentration of 2.9 x 10 6 viable spores/ml. Greatest mortality occurred eight days after infection with B. bassiana, and 10 days after infection with B. tenella.
