摘要
以花椒果皮为研究对象,赤拟谷盗为供试虫源,采用点滴法、饲喂法、三角瓶密闭熏蒸法和培养皿滤纸涂药法检测不同花椒果皮提取物对赤拟谷盗的的触杀、胃毒、熏蒸及趋避作用。实验结果显示,正丁醇萃取部分对赤拟谷盗的触杀活性最高,其LC50值为1.086 463 g/m L,石油醚提取部分对赤拟谷盗趋避活性最高,其趋避率可达到93.617%,花椒果皮不同极性段的提取物均有一定的杀虫活性。
The contact action,stomach action,fumigation action and repellent action of different extraction to tribolium castaneum were studied by dropping, feeding,Triangle bottle airtight fumigation and Residual films. The result indicated that the contact action reached the highest level that LC50 was 1.086 463 g/mL and the repellent action reached a high level that was 93.617%when Zanthoxylum were handled after n-butyl alcohol leached and extracted by petroleum ether. The result showed that the different Zanthoxylum extraction exhibited both insecticidal activity,and were worthy investigation.
