小菜蛾乙酰胆碱酯酶(AChE)的性质研究表明,不同种群小菜蛾成虫与幼虫AChE活性相比,差异极显著,成虫是幼虫的5～7倍;武汉种群小菜蛾成虫和幼虫AChE与底物的亲和力最小。小菜蛾谷胱甘肽鄄S鄄转移酶(GST)的性质研究表明,宣化、武汉、云南3个田间种群GST活性较高,明显高于台湾敏感品系;北京种群GST活性较低,与台湾敏感品系近似。此研究为进一步分析小菜蛾不同种群、不同虫态抗药性差异提供了依据。
The study on AChE of Plutella xylostella showed that there was a significant difference in AChE activity between adult Plutella xylostella and adult larvae, and the adult larvae were 5 to 7 times as much as adult larvae. AChE and substrate The least affinity The study on the properties of glutathione S-transferase (GST) in diamondback moth (Plutella xylostella) showed that GST activity in three field populations in Xuanhua, Wuhan and Yunnan was higher than that in Taiwan, while the GST activity in Beijing was lower than that in Taiwan Line approximation. This study provided the basis for further analysis of different populations of Plutella xylostella and differences in resistance between different insect states.
