不同温度下辣根素对赤拟谷盗和玉米象的熏蒸效果
首发时间:2010-04-02
摘要:利用三角瓶熏蒸法,测定了辣根素对赤拟谷盗和玉米象成虫的熏蒸毒力。结果表明,辣根素对赤拟谷盗和玉米象成虫均具有明显的熏蒸效果,其中,玉米象对辣根素的敏感性更强。当熏蒸处理时间相同时,辣根素对两种仓储害虫的熏蒸效果取决于温度。在供试温度(28℃、20℃、10℃)下,辣根素对赤拟谷盗和玉米象成虫的LC50分别为0.965、0.996、1.231μL/L和0.683、0.741、1.073μL/L。

Fumigation toxicity of AITC At Different Temperatures Against Tribolium castaneum (H.) And Sitophilus zeamais (M.)
Abstract:AITC was tested for its insecticidal activities against adults of Tribolium castaneum (H.) and Sitophilus zeamais (M.) by the method of triangle bottle obturation fumigant.Good insecticidal activity was achieved with AITC and Sitophilus zeamais was more susceptible to AITC. After the same exposure,the susceptibility of two stored-grain insects to AITC differed according to the temperature. At different temperature (28,20,10℃), the LC50 value of AITC against adults of Tribolium castaneum and Sitophilus zeamais was 0.965,0.996,1.231μL/L and 0.683, 0.741,1.073μL/L after 24h of exposure respectively.
