    摘要:

    [目的] 探究麦蛾柔茧蜂最适的冷藏温度及虫态,为麦蛾柔茧蜂在生物防治的应用提供基础。[方法] 将麦蛾柔茧蜂的4种虫态(卵、幼虫、蛹和成虫)置于-4、0、4、10℃温度下冷藏,观察其存活率,以确定其冷藏的最适虫态和最适温度。随后测定最适冷藏条件下,麦蛾柔茧蜂的生命参数。[结果] 致死中时间(T50)表明,麦蛾柔茧蜂以蛹期在10℃条件下冷藏为最佳,冷藏12 d时存活率仍达到75.25%。麦蛾柔茧蜂在10℃条件下冷藏后,首日产卵量在冷藏后期显著下降,麦蛾柔茧蜂性比显著降低,但冷藏3 d后其均值又逐渐恢复。茧蜂发育历期在冷藏后无显著变化。[结论] 以椰子织蛾为寄主的麦蛾柔茧蜂于蛹期在10℃条件下冷藏12 d仍具有良好的利用价值,这可为麦蛾柔茧蜂在生物防治中的应用提供依据。

    Abstract:

    [Aim] The study examined the potential of cold temperature for the storage of the biological control Habrobracon hebetor, so as to provide a basis for the application of H. hebetor in biological control.[Method] The four stages (egg, larva, pupa and adult) of the parasitoid H. hebetor were stored at -4, 0, 4, 10℃ and their survival rates were observed to determine the optimum cold storage stage and temperature. Then, the life parameters of the parasitoid were determined under the optimum cold storage conditions.[Results] The median lethal time (T50) showed that the optimum cold storage condition for the parasitoid were pupa stage at 10℃. The survival rate was 75.25% after 12 days of cold storage. After cold storage at 10℃, the fecundity and sex ratio decreased significantly. While the average value gradually recovered after 3 days of cold storage. There was no significant difference in the developmental duration of the parasioid after cold storage.[Conclusion] The parasitoid could still be used after 12 days cold storage at 10℃ in the pupal stage, which provided a basic information for the application of the parasitoid in biological control.
