Description :
Sustainable agriculture in the 21st century will rely increasingly on microbial control and other alternative interventions for pest management that eco friendly. For biological control of insects pests, entomo-pathogenic microorganism and viruses play a major role. Entomopathogenic fungi are important naturally occurring antagonists of insect pests with a worldwide distribution. Research on these fungi has started about 100 years ago and after a decline, was reactivated since last 30 years. A number of entomopathogenic fungi have been identified and there potential as biological control agent. The present investigation were undertaken to study the isolation and screening of various entomopathogenic fungi viz., Beauveria and Metarhizium against third instars larvae of agricultural crop larvae the germination percentage of the isolates on different media were studied. Effective isolates Metarhiziun anisopliae 3 were used for percent germination studies on the different media and the media used were PDA, PYGA, . Out of four media tested the B. bassiana showed the highest germination on PYGA (92.30%). The soil sample from Agriculture College, shows presence of entomopathogenic fungi, which need the further more isolation and study for the efficiency against different insects pests. Among the five isolates Metarhizium anisopliae 3 show more effectiveness against third instars larvae of agricultural crop
