Abstract

The Asian locust (Locusta migratoria L.) remains one of the most dangerous pests of agricultural crops in arid regions, including southern Kazakhstan. An effective and environmentally friendly alternative to chemical insecticides is the use of entomopathogenic fungi. This study evaluated the pathogenicity of three Beauveria bassiana strains cultivated on rice using solid-state fermentation. The average conidial yield ranged from 2.3×10⁹ to 4.1×10⁹ spores per gram of dry substrate, with viability ranging from 85% to 95%. Bioassays were conducted using an immersion method, exposing locust nymphs to a suspension containing 1×10⁸ conidia/mL. The strain BLе1(k)-07 exhibited the highest virulence, causing up to 95% mortality by the 15th day post-inoculation. The results confirm the high biological activity of the tested strains and demonstrate their potential as effective biocontrol agents. These findings provide a basis for the development of bioinsecticides targeting L. migratoria, with further plans for field trials and formulation improvements for integrated pest management programs in arid agroecosystems.
