Bioefficacy of entomopathogenic fungi against Aphis craccivora in groundnut.

摘要

The pathogenicity of Beauveria bassiana, Paecilomyces fumosoroseus and Verticillium lecanii against Aphis craccivora was assessed on potted groundnut (cv. TMV 7) plants to record the potential candidates for field evaluation. The applied conidial concentrations of each fungus were 1x1010, 1x108 and 1x106. In general, A. craccivora mortality increased when fungal spore concentration and exposure time increased. V. lecanii was most virulent to A. craccivora.
