中文摘要：

结合的率测量(3-[I125 ] iodotyrosyl ) α - bungarotoxin 在有菱形斑纹的蛾在在神经醋胆素受体和杀虫药剂抵抗的三种类型之间的关系的分析被使用， Plutella xylostella (L.) 。在 dimehypo 抵抗的紧张并且在 cartap 抵抗的紧张，神经醋胆素受体出现了在到一角银币低亚硫酸钠和汽车龙头，分别地，到 ligand 的有约束力的率易受影响的紧张是约 66 和 60% 的敏感显著。到在 deltamethrin 抵抗的紧张的 deltamethrin 的敏感没显示出可见变化。这些结果显示在到杀虫药剂力量的神经醋胆素受体的敏感的衰落是到在有菱形斑纹的蛾的沙蚕属毒素杀虫药剂抵抗的潜在的机制。

英文摘要：

The combinative rate measurement of （3-[I125] iodotyrosyl） α-bungarotoxin was applied in the analysis of the relation between nerve acetylcholine receptor and three types of insecticide resistance in diamondback moth, Plutella xylostella （L.）. In the dimehypo-resistant strain and in the cartap-resistant strain, the nerve acetylcholine receptor showed the remarkable insensitivity to dimehypo and cartap, of which the binding rate to ligand was approximately 66 and 60%, respectively, of the susceptible strain. The sensitivity to deltamethrin in the deltamethrin-resistant strain did not show visible change. These results indicated that the decline in the sensitivity of nerve acetylcholine receptor to insecticide might be a potential mechanism to nereistoxin insecticides resistance in the diamondback moth.
