dc.description.abstractAn attempt was made to isolate and characterize native entomopathogenic fungi. Nine insect mycopathogens, belonging to seven genera were found naturally occurring in the nine districts of Northern Karnataka. Morphological variation among the field collected isolates of M. anisopliae (Ma2) and V. lecanii (VI1) for various parameters like, hyphal and conidial characters, sporulation and spore yield were recorded. Pathogenicity of V. lecanii to aphids, whitefly and mites and that of M. anisopliae to Americain bollworms £ind rhinocerous beetle was proved in laboratory. Among different carbon sources tested, starch proved superior for both the mycopathogens NH4 (SO4) and KNO3 were superior as nitrogen source. Bajra and rice grains served as most productive media for conidial growth of Ma2 and Vll with an yield of 22.77 x 10^ and 24.59 x 10® conidia per g of media, respectively. Among pesticides tested, fungicides showed maximum inhibition followed by insecticides and weedicides. The persistence of mycopathogens (Ma2 and Vll) was higher in soil (upto 16 months) than in phylloplane (upto 3 months). In general, all the carrier material had more conidial viability when stored in refrigerated and deep freezer condition and a reduction of more than 10 per cent and 8 per cent in refrigerated and deep fereezer was observed after 150 DAS respectively. Oil formulations proved better than wettable powder.en_US
