Abstract Ten varieties of pearlmillet (RHB-173, RHB-177, MPMH-17, HHB-67, Pro Agro-9450, Pro Agro-9001, Pioneer 86 m 86, Pioneer 86 m 84, Pioneer 86 m 38 and Raj-171.) were evaluated for reaction to Corcyra cephalonica Staint. in the laboratory conditions. The adult emergence (F1), weight losses and susceptibility index in these varieties were ranged from 9.33-32.00, 10.44–31.69% and 2.77–6.82, respectively, the minimum in Pioneer 86 m 86 and maximum in Raj-171; other varieties were in the middle order. The seed damage recorded in different varieties ranged from 23.67–75.84%, the minimum in Pioneer 86 m 86 (23.67%), Pro Agro-9450 (25.55%) and Pro Agro-9001 (28.33%), these treatments were found at par each other. The Raj-171 was found to be badly infested (75.84% grain damage) which differed significantly over other varieties. The developmental period of the pest varied from 50.88–80.61 days in different varieties, minimum being in Raj-171 and maximum in Pioneer 86 m 86.

Eight isolates of entomopathogenic fungi were evaluated as dried conidia against the rice moth,  Corcyra cephalonica. In bioassays two isolates of Beauveria bassiana (BbGc and BbPs) and one isolate of Metarhizium anisopliae (MaPs) consistently gave high mortality to C. cephalonica larvae. Formulations in either kaolin, talc or tapioca flour (20 % w/w a.i.) thoroughly mixed with long grain rice in plastic cups (8 cm diameter by 5 cm) gave complete larval mortality by the 12th day of treatment. However, in general those formulated in kaolin and talc were more efficacious and faster to kill compared to those formulated in tapioca flour or the unformulated control. Even at the lowest rate of 0.05 g BbGc in kaolin provided 100% mortality 7 days after introduction compared with other dust formulations. Isolate BbGc in kaolin and talc administered at 0.4 g a.i. in 200 g rice packed in plastic kept at room temperature provided protection against the rice moth up to 4 months of storage. Larval mortality in excess of 90% was obtained 15 days after introduction. Formulations of MaPs was effective only within the first month of storage beyond which infectivity rapidly declined.
