黄花蒿精油对双斑萤叶甲的熏蒸活性及体内几种酶活力的影响

摘要

We tested the fumigation activity and several enzymes activities of essential oil from Artemisia annua L. against Monolepta hieroglyphica (Motschulsky) adult in the body. The result showed that the oil had obvious fumigation activity against insects. At dosage of 25.00 μL/L, and 8 h fumigating period, the corrected mortality rate reached 83.33 % . Essential oil of Artemisia annua L. significantly inhibited the AchE; The activity of GSTs was obviously induced; The activity of ACP and ALP were inhibited to some extent; The activity of POD was not obviously affected.%测定了黄花蒿精油对双斑萤叶甲的熏蒸活性及体内几种酶活力的影响.结果表明:双斑萤叶甲在熏蒸处理8h后,25.00μL/L处理组的校正死亡率达到83.33％,表现出明显的熏蒸作用.黄花蒿精油对双斑萤叶甲体内乙酰胆碱酯酶活力表现出明显的抑制作用,对谷胱甘肽-S-转移酶表现出明显的诱导作用,对酸性磷酸酯酶、碱性磷酸酯酶活力表现出一定的抑制作用,对过氧化物酶影响不明显.
