ВИРУЛЕНТНОСТЬ НОВЫХ ПРИРОДНЫХ ИЗОЛЯТОВ ГРИБА Beauveria bassiana ДЛЯ НАСЕКОМЫХ ИЗ РАЗЛИЧНЫХ СИСТЕМАТИЧЕСКИХ ГРУПП

Abstract

Investigate the new strains of Beauveria bassiana (Bals.) Vuill isolated from different insects of South Kazakhstan region. It was found out that low-, medium- and high- virulent isolates. The isolates with high virulence to the insects of certain order were more active against the other insect orders. The close correlation (R>0,78) between isolates virulence against the beetle Chrysomela saliceti L and locusts Locusta migratoria L. was shown. With it was found out that strains isolated from one insect species in the same place can have rather different virulence.
