Abstract

The isolation and identification studies revealed that the EPN isolates from the Sorghum cropping system was Heterorhabditis indica and showed pathogenicity to the third instar larvae of Corcyra cephalonica in laboratory. The pathogenicity studies revealed that mortality in 3rd, 4th and 5th instar larvae of C. cephalonica and H. armigera was highest at 30 IJs/100µl concentration of EPN suspension. The reproduction and multiplication studies revealed that recovery of EPN Infective Juveniles (IJs) was highest in the 3rd and 4th instar larvae of C. cephalonica and H. armigera when infected with EPN isolates from sorghum cropping system.
