| dc.description.abstract | Fungi against some Lepidopteran Pests. The studies on pathogenicity of Beauveria bassiana (Balsamo) Vuillemin, Metarhizium anisopliae (Metschnikoff) Sorokin against some lepidopteran insects, growth and sporulation of fungi on different vegetables, grains, synthetics and agro wastes, compatibility with different fungicides, insecticides and essential oils, interaction of fungi with insecticides for the management of Spilarctia oblique (Walker), preparation of formulation and assessment of conidial viability at different temperature and storage were conducted. In bioefficacy test strain ITCC- 6264 of B. bassiana was found more virulent than respective isolates against S. obliqua and S. litura while ITCC- 6265 isolate of M. anisopliae found more virulent against both the test insects. Among entomogenous fungi B. bassiana has more potential to kill both of the test insects. For growth and sporulation of B. bassiana, potato dextrose broth and bean broth, bajra + 1% yeast, kondrytiev, CDA and wheat bran + 10% molasses were found best, while for M. Anisopliae Ipomoea batata, sorghum, goral and SDA were found most suitable. Among different plant protecting chemicals bavistin, captan, mancojeb, Chlorothalonil, dadeci, jatropha, neem proved relatively safer to B.bassaina while bayleton, profenophos, neem, jatropha, patchouli proved relatively safer to M. anisopliae. dadeci, profenophos, triazophos and quinalphos could be used with both entomogenous fungi for managing S. obliqua. Temperature 250C and 300C were found best for growth and sporulation of B. bassiana and M. anisopliae respectively. Maximum conidial germination was recorded at 100% RH levels for both the isolates. Storage temperature 40C was found best for the maintenance of conidial viability. Conidial viability decreased with the increase in storage temperature. Talc and sorghum flour maintained higher viability. | en_US |
