摘要
采用索氏提取法,以乙醚为有机溶剂浸提木香薷提取物,研究其对玉米象、赤拟谷盗成虫的驱避作用、触杀作用、种群抑制作用和熏蒸作用.结果表明,木香薷乙醚提取物对赤拟谷盗成虫的驱避作用较强,作用72 h后驱避率仍保持在85%以上,对玉米象成虫的驱避作用较弱.木香薷乙醚提取物对玉米象和赤拟谷盗成虫的触杀作用和当代种群抑制作用均较弱,但对二者的熏蒸作用较强,处理4 d后玉米象当代成虫死亡率达到95%以上,赤拟谷盗当代成虫死亡率达到100%.
The eontrollin Soxhlet extraction, inclu g effects of anhydrous diethyl ether extracts ding repellent, contact, population inhibition from Elshohzia stauntonii through the and fumigation activities, were investigated in this paper. The resuhs showed that: E. stauntonii extracts possessed an extremely strong repellent activity against Tribolium castaneum adults and weak repellent activity against Sitophilus zeamais adults, and the repellent rate still kept over 85% for T. castaneum adults at 72 h after treatment. E. stauntonii extracts exhibited weak contact, current population-inhibition activities and strong fumigation activity against S. zeamais and T. castaneum adults, and current population mortality was over 95% for S. zeamais adults, 100% for T. castaneum adults at 4 d after treatment respectively.
