| Abstract: | Different biological and ecological characteristics, virulence, sporulation, conidia bourgeon, Protea-Bse activity leve and colony growth of 6 strains of Beauveria bassiana were measured respectively. The results were calculated by grey relational analysis and the optimum sequence was built from the professional comparison of each strain''s characteristics. Two strain''s have a potential of appling in mass production, BD-B015 and BD-B038 were abtained. The revisory mortality to Laphygma exigua Hubner were 88.33% and 86.70%.The infected rate were 86.67% and 85.27%. |
