The rice leaf roller or leaf folder, Cnaphalocrocis medinalis (Guenee) (Lepidoptera: Pyralidae), is a serious pest of rice
crop in Pakistan. The present study was carried out to evaluate the virulence of the entomopathogenic fungi (EPF)
Beauveria bassiana, Verticillium lecanii, and Metarhizium anisopliae against the third instar of C. medinalis larvae.
Larvae were exposed to fungi under controlled conditions at the available commercial concentration (1 × 108
conidia ml−1). The results showed 73.33, 57.78, and 74.44% mortality rates in the in vitro assay and 56.67, 41.11 and
52.78% in the greenhouse assay of B. bassiana, V. lecanii, and M. anisopliae, respectively. The maximum mycosis
from cadavers of C. medinalis was observed at B. bassiana treatment in the in vitro assay (70%) and in the
greenhouse assay (53.78%). The maximum sporulation from C. medinalis cadavers was observed at B. bassiana
treatment in the in vitro assay (144.67 conidia ml−1) and in greenhouse assay (96.67 conidia ml−1). These results
favor the alternative use of EPF in organic rice production for management of C. medinalis.
