Abstract
Pathogenicity of the entomopathogenic fungi, Beauveria bassiana and Metarhiziurn anisopliae towards certain stored product insects; Callosobruchus maculatus F., Rhyzopertha dominica (F.), Sitophilus oryzae (L.) and Oryzaephilus surinmensis (L.) was investigated. Results revealed that B. bassiana was more efficient against cowpea weevil, C. maculatus, R. dominica. and O. surinmensis than M. anisopliae. However, M. anisopliae was efficient against S. oryzae. Adults of the four insects species responded in fluctuated manner; the C. maculatus was the most susceptible species to both fungi, followed by R. dominica then O. surinmensis, while S. oryzae was the least. The study concluded that both fungi; B. bassiana and M. anisopliae have a potential for effective and economically feasible control of tested stored product insects.
