| 摘 要： | 为了明确低温下松褐天牛肿腿蜂雌蜂的最佳储存时长，本试验在10 ℃条件下储存松褐天牛肿腿蜂雌蜂，研究不同贮存时长后成蜂的子代发育历期和数量。结果表明：松褐天牛肿腿蜂雌蜂死亡率随储存时长增加逐渐增加，60 d时死亡率较低，其累积死亡率为6.90%，至120 d时，累积死亡率达42.46%，雄蜂寿命明显比雌蜂短。不同储存时长对松褐天牛肿腿蜂的子代发育历期影响显著，短期储存雌蜂可以缩短松褐天牛肿腿蜂的产卵前期。松褐天牛肿腿蜂子代发育历期随着成蜂储存时长的增长呈上升趋势，其中卵历期差异较小，平均为3～4 d，幼虫历期、蛹历期和卵至成虫的发育历期差异显著。随着成蜂储存时间的增加，松褐天牛肿腿蜂子代总数和子代雌蜂数呈下降趋势，不储存的子代总数和子代雌蜂数最多，平均59.96头和57.92头；至150 d时，子代总数和子代雌蜂数均显著下降，仅30.52头和26.04头。松褐天牛肿腿蜂子代雄蜂数和雄性比在储存150 d时显著增加，其他处理差异不显著。以上研究表明：10 ℃下，储存60 d为最佳储存时长，最长不宜超过120 d。本试验为松褐天牛肿腿蜂的储存及应用提供依据。

| Abstract: | IThe optimal low temperature storage duration of Sclerodermus alternatusi Yang (Hymenoptera:Bethylidae) females was determined by measuring the survival of parental parasitoids and offspring population size and developmental duration of parental parasitoids stored at 10℃ for varying durations.The results showed that the mortality of S.alternatusi females increased with the storage duration,varying from 6.90% at storage of 60 days to 42.46% at storage of 120 days.The life span of S.alternatusi males was shorter than that of females.The duration of immature stage of S.alternatusi offspring was significantly affected by storage duration,the pre-oviposition period of S.alternatusi females was shortened by short low temperature storage.And the offspring developmental duration elongated with the increase of low temperature storage duration,among which the egg stage was about 3-4 d in all storage duration treatments,and the durations of larval stage、pupal stage and immature stage differed significantly between storage duration treatments.The total offspring number and the female number decreased with the elongation of storage duration,and the total offspring number and the female number were 59.96 and 57.92,respectively,for the no-storage parental parasitoids,but dropped to 30.52 and 26.04,respectively,in the parental parasitoids stored for 150 days.The results show that,at 10℃,the optimal storage duration for the parasitoids is 60 days,and the longest storage should be less than 120 days.The study provides reference for rearing and application of S.alternatusi in control of the longhorn beetles. |
