| 中文摘要: |
| 室内采用浸叶法测定了柑橘木虱Diaphorina citri敏感种群与田间种群对广东常用药剂的敏感性，明确了柑橘木虱田间种群对阿维菌素、高效氯氰菊酯、吡虫啉、噻虫嗪、啶虫脒和甲维盐6种药剂的抗药性。柑橘木虱田间种群对70%吡虫啉水分散粒剂、20%啶虫脒可溶液剂、3%甲维盐微乳剂处于低水平抗药性，LC50抗性倍数分别为5.89倍、8.53倍和9.86倍；对25%噻虫嗪水分散粒剂、10%高效氯氰菊酯乳油、1.8%阿维菌素乳油仍具有较高的敏感性。田间防治柑橘木虱推荐不同作用机理的药剂交替使用，综合运用多种防控措施，以延缓柑橘木虱抗药性的产生。 |
| 英文摘要: |
| Sensitivity of Diaphorina citri sensitive population and field population to commonly used pesticides in Guangdong was determined with leaf-dip method. The resistance was clarified of D. citri field population to Abamectin, Beta-cypermethrin, Imidacloprid, Thiamethoxam, Acetamiprid, and Emamectin Benzoate. D. citri field population was at low levels of resistance to 70% Imidacloprid WG, 20% Acetamiprid SL and 3% Emamectin Benzoate ME, and the LC 50 resistance ratios were 5.89, 8.53 and 9.86, respectively. D. citri field population was still highly sensitive to 25% Thiamethoxam WG, 10% Beta-cypermethrin EC, and 1.8% Abamectin EC. In the field, it is recommended to use insecticides with different action mechanisms and use multiple prevention measures to control D. citri to delay the emergence of insect resistance. |
