摘要
室内测定了不同化性苜蓿切叶蜂成蜂对球孢白僵菌(Beauveria bassiana(Balsamo))的敏感性。在28℃,RH60%的条件下,喷施白僵菌后二化种群死亡速度较快,72h后死亡率为67%,而一化种群72h后死亡率为38%。结果表明,成蜂对白僵菌的敏感性在化性间存在差异,二化种群成蜂对球孢白僵菌具有较高的敏感性(P<0.05),抗性较差。
The susceptibility of two strains of alfalfa leaf-cutting bee to Beauveria bassiana was studied in laboratory.The bivoltine adult died faster than the univoltine adult under 28℃ and RH 60% after treatment,the mortality was 67% and 38% at 72 hours respectively.There was significant difference on susceptibility between two strains of the bee to B.bassiana.The bivoltine adult was more susceptible to Beauveria bassian(P<0.05).
