Abstract
Different rates of dry mycelium and a suspension of conidia of the entomogenous fungus Metarhizium anisopliae (Metsch.) Sorokin were evaluated for the suppression of populations of the brown planthopper, Nilaparvata lugens Stal on rice. The mycelium was applied at rates equivalent to 700, 3500, and 7000 g/ha; the conidia at a rate equivalent to 2.5 x 10 to the twelfth power conidia/ha. Significant control of the populations was achieved at two weeks after application and up to harvest of the rice crop; differences between treatments were present but not consistent. Dry mycelium preparations of M. anisopliae should be further evaluated for use in control of the brown planthopper.
