中文摘要:为明确高温对松毛虫赤眼蜂Trichogramma dendrolimi发育和寄生能力的影响,采用生物学观察法在室内监测米蛾Corcyra cephalonica卵内不同发育时期的松毛虫赤眼蜂在经历高温40℃处理1 h或35℃处理6 h后其当代和子代蜂的世代历期、羽化率、寄生率和雌蜂率并进行分析。结果表明,高温40℃处理1 h有利于松毛虫赤眼蜂的发育,于幼虫期处理后其当代蜂世代历期明显缩短,于胚胎期和蛹期处理后其当代成蜂羽化率显著提高;然而,高温35℃处理6 h对松毛虫赤眼蜂的发育和寄生能力具有显著的负面影响,各发育时期经历高温处理后当代成蜂羽化率均显著降低,幼虫期经历高温处理后其当代成蜂的雌蜂率、寄生率和子代成蜂的羽化率均显著降低。表明高温对松毛虫赤眼蜂具有显著影响,繁育时适当优化温度可以提高扩繁效率,但运输和释放时应避免高温暴晒以降低防控效率损失。

Abstract:To elucidate the impact of high temperature on the development and parasitic capacity of pine caterpillar miunte egg parasite Trichogramma dendrolimi, biological investigation was conducted to record the generation duration, emergence rate, parasitism rate and female rate of the treated generation and the offspring of T. dendrolimi after thermal treatment at 40℃ for 1 h and at 35℃ for 6 h. The results showed that high-temperature treatment at 40℃ for 1 h was beneficial to the development of T. dendrolimi. When T. dendrolimi was treated at larval stage, the generation duration of the treated wasps was shortened, and its adult emergence was increased when treated at embryo and pupal stages. However,high-temperature treatment at 35℃ for 6 h imposed significantly negative impacts on the development and parasitic capacity of T. dendrolimi. The adult emergence of the treated generation was notably lowered regardless of the developmental stages that were treated; the female rate and the parasitic capacity of the treated wasps and the emergence rate of the offspring were all significantly decreased when treated at the larval stage. The results indicated that high temperature had obvious impacts on T. dendrolimi.An optimized thermal treatment helps to enhance the efficacy of artificial rearing, and avoidance of high heat and solar exposure during transportation and release would prevent the loss of control efficacy.
