重点介绍了冰草的不同溶剂提取物对桃蚜的杀虫活性及其对蚜虫体内蛋白酶、谷胱甘肽-S-转移酶活性的影响。结果表明,冰草氯仿和水提取物对桃蚜有较好的内吸活性,并对桃蚜体内蛋白酶、谷胱甘肽-S-转移酶活性均有明显抑制作用,而在触杀处理中,提取物对蚜虫各酶系活性的影响不明显。
This paper mainly introduced the insecticidal activity of different solvent extracts of Agropyron grass on Myzus persicae and its effect on the activity of protease and glutathione-S-transferase in aphids. The results showed that the chlorpyrifos and water extract had good systemic activity on Myzus persicae and significantly inhibited the activity of protease and glutathione-S-transferase in Myzus persicae, The effects of extracts on the activities of aphids were not obvious.
