【摘要】 橘小实蝇（Bactrocera dorsalis）是严重危害云南石榴产业的重要检疫性害虫，其幼虫蛀果为害，成虫飞翔能力强，导致化学防治困难。利用老熟幼虫脱果入土化蛹这一关键时期实施生物防治，成为具有潜力的防控途径。本研究通过评估球孢白僵菌（Beauveria bassiana）对天敌印度实蝇姬小蜂（Aceratoneuromyia indica）的安全性，开展菌蜂田间协同防控试验。室内安全性评价表明，在工作浓度为1.5×10~8 CFU/mL时，球孢白僵菌对印度实蝇姬小蜂安全；田间防控效果显示，菌蜂协同处理的校正防效达53.75%，显著高于单一菌剂（32.24%）和寄生蜂（18.11%）处理，且持效期延长13 d。研究结果为橘小实蝇的绿色防控新技术提供了科学依据和技术支持。更多还原

【Abstract】 Bactrocera dorsalis is a significant quarantine pest that causes severe damage to pomegranate production in Yunnan Province. Its larvae bore into fruits,and the adults have strong flight ability,making chemical control challenging. Utilizing the critical period when mature larvae drop from fruits and enter the soil to pupate presents a promising opportunity for biological control. Our study evaluated the safety of Beauveria bassiana to Aceratoneuromyia indica and conducted field trials on the combined application of B. bassiana and A. indica. Laboratory safety assessments confirmed that B. bassiana was safe to A. indica at a working concentration of 1.5×10~8CFU/mL. Field control efficacy results showed that the combined application of B. bassiana and A. indica achieved a corrected control efficacy of 53.75%,significantly outperforming individual treatments(32.24% for B. bassiana alone and 18.11% for A. indica alone) and extending the duration of pest suppression by 13 days. The research results provide a scientific basis and technical support for the development of novel green control techniques against B. dorsalis.更多还原
