Metarhizium anisopliae </em>entomopathogenic fungus is one potensial of the biological agent that can be used to control <em>C. pavonana. </em>This study aimed to investigated the effect of storage duration on viability, bioactivity and persistence of <em>M. anisopliae </em>after formulated to control <em>C. </em><em>pavonana. </em>Laboratory experiment was arranged in completely randomized design with the treatment was storage duration that included 2,4,6,8 and 10 weeks that replicated three trials. The variabels to be measured were viability and bioactivity at concentrations106, 107, and108. Field experiment used T Student test with treatment was duration of <em>M. anisopliae </em>formulation survive and its persistence on <em>C. pavonana</em>. Laboratory experiment results showed that the best storage duration of formulation on Metarhizium viability was pellet frmulation at 4th week 4 after storage. While the best bioactivity was pellet formulation with concentration 107 at 10 weeks after storage. Field experiment results showed that <em>M. anisopliae </em>formulation could be survived and its persistence to control pests <em>C. pavonana </em>until 4th day after application, either pellet or powder formulation. </p> ER -
