In this experiment, through testing the B.bassiana colony space persistent change on the lawn by isolate medium, explore the application time of field climate and other factors on the inoculum effect. Results: The control effect of lawn locust, Suspension emulsion mortality rate was 74.2%, Bt bacterium mortality rate was72.2%, B.bassiana bacteria mortality rate was70.1%. Test the population dynamics of B.bassiana surviving in lawn during 30 days by PPDA medium, we found that different strains of time has a great influence to the spore viability. Each cell showed obvious changes, the overall downward trend evident. After application the lawn every part of colony persistent distribution for soil> leaf > air; the best application time is 6:00 p.m.
