摘要：[目的]为了明确温度对松褐天牛肿腿蜂繁殖和发育的影响,进而为其人工繁育和生物防治应用提供科学依据。[方法]在21,24,27,30,33℃的恒温条件下人工繁育松褐天牛肿腿蜂,记录各虫态发育历期及子代数量,并计算各虫态发育起点温度和有效积温。[结果]表明,松褐天牛肿腿蜂各虫态发育历期随着温度的升高而缩短,如5组温度处理下的卵期分别为3.29±0.14,2.89±0.17,2.61±0.14,2.16±0.11和1.86±0.93 d。卵、幼虫、蛹的发育起点温度分别为6.99±2.12,10.67±3.43和13.5±2.71℃,有效积温分别为49.28±5.08,166.67±34.02和225±43.30日·度。温度对子代数量及雄性占比也有显著影响,温度超过30℃后,子代数量及雄性占比显著下降。[结论]适度升温可有效促进肿腿蜂的繁殖和发育,但温度超过适温则不利于母蜂寄生和子代发育,人工繁育松褐天牛肿腿蜂的适宜温度范围是24-30℃。
[Objective] To clarify the effect of temperature on the reproduction and development of Sclerodermus alternatusi, the ectoparasitoid of Monochamus alternatus, and provide scientific supports for artificial rearing of parasitoid and biological control utilization in practice.[Method] The parasitoids were reared artificially at different constant temperatures (21, 24, 27, 30, and 33℃) under laboratory conditions. The development duration of each stage and the progeny number were recorded. The development threshold temperature and effective accumulated temperature were also calculated by using the least squares method.[Result] It showed that the development durations of S. alternatusi declined with the increase of temperature. For example, the durations of egg stage at the different temperature were 3.29±0.14, 2.89±0.17, 2.61±0.14, 2.16±0.11 and 1.86±0.93 days, respectively. The development threshold temperatures for egg, larva, pupa were 6.99±2.12, 10.67±3.43 and 13.5±2.71℃, while the effective accumulated temperatures were 49.28±5.08, 166.67±34.02 and 225±43.30 degree-day respectively. The temperature also showed significant effects on the amount and sex ratio of the progenies. As the rearing temperature exceeded 30℃, the amount and male proportion of the progenies decreased significantly.[Conclusion] These findings reveal that the proper rearing temperature can improve the reproduction and development of S. alternatusi. However, once the temperature is over the optimum threshold, the parasitism of maternal parasitoids and development of progenies will be adversely affected. The optimum temperature range for artificial mass rearing is 24-30℃.
