| 摘 要： | 目的了解硫酰氟熏蒸剂对杂拟谷盗(T.confusum)生殖力的影响,为仓储害虫防治治理策略的制定提供充分依据。方法采用密闭熏箱法,用不同浓度的硫酰氟在22℃条件下对杂拟谷盗幼虫和成虫进行熏蒸处理,观察处理后存活的的幼虫及成虫在温度28±1℃,湿度≥60%的温箱中发育及繁殖情况。结果浓度为16g/m3和10g/m3的硫酰氟对杂拟谷盗熏蒸2.5h,成虫死亡率高于幼虫,处理后的杂拟谷盗幼虫及成虫能够继续发育和生殖。结论杂拟谷盗对硫酰氟的敏感性表现为成虫大于幼虫,硫酰氟对熏蒸后存活幼虫和成虫发育繁殖能力影响小。

| Abstract: | Objective Provide references for the formulation of stored-grain insect control strategies by studying sulfury fluoride＇s influence on the reproductive ability of T.confusum.Methods Carry out fumigation to larvae and adult of T.confusum with different dosage of sulfury fluoride in sealed container under 22 ℃, and then observe the development and fecundity of the alive larvae and adult of T.confusum in thermostat at 28±1 ℃ and ≥60% RH.Results Under the conditions of 2.5h fumigation with 16g/m3 and 10 g/m3 sulfury fluoride concentration, the mortalities of adult is higher than larvae, and the alive ones can continue to develop and reproduce.Conclusion The adult of T.confusum are more susceptible to sulfury fluoride than larvae, and sulfury fluoride has little influence on the development and reproduction of the alive ones. |
