摘要:

在16℃、20℃、24℃、28℃和32℃恒温下,观察了温度对感染沃尔巴克氏体的松毛虫赤眼蜂发育、存活和繁殖的影响,组建了相应温度下的实验种群生命表。结果表明,在实验温度范围内,感染沃尔巴克氏体的松毛虫赤眼蜂的发育历期随着温度的升高而逐渐缩短,5个温度下感染沃尔巴克氏体的松毛虫赤眼蜂世代的发育历期分别为23.2、17.8、13.2、11.1和7.8天,世代的发育起点温度和有效积温分别为7.40℃和212.69日·度,内禀增长率(rm)和净生殖力(R0)分别介于0.2448~0.4584和28.00~84.03之间。结果提示温度24℃~28℃为繁殖感染沃尔巴克氏体的松毛虫赤眼蜂的理想温度条件。

Abstract:

 Development and parasitization of Trichogramma dendrolimi infected by Wolbachia were observed at 16℃, 20℃, 24℃, 28℃ and 32℃ respectively. The results showed that the developmental duration of T. dendrolimi infected by Wolbachia was affected by temperature. The higher the temperature, the shorter the duration. The whole developmental duration was 23.2 d, 17.8 d, 13.2 d, 11.1 d, and 7.8 d at 16℃, 20℃, 24℃, 28℃ and 32℃, respectively. The thermal threshold, the effective accumulated temperature, the innate capacity of increase (rm) and the net reproduction rate (R0) of T. dendrolimi infected by Wolbachia were estimated as 7.40℃, 212.69 degree-day, 0.2448-0.4584 and 28.00-84.03, respectively. The results suggested that the optimal reproduction temperature of T. dendrolimi infected by Wolbachia was 24℃-28℃.
