| 中文摘要: |
| 柑橘木虱（Diaphorina citri K瑄wayama）是柑橘黄龙病的媒介昆虫，目前，其防治以化防为主。为了监测化学农药的防治效果，选用9种柑橘生产上常用的药剂对江西赣州市信丰县的柑橘木虱田间种群进行药效测定，并用华南农业大学昆虫生态研究室用九里香饲养的种群作为敏感对照。测定虫态为成虫。结果表明，对信丰种群，处理24h后敌敌畏效果最好，死亡率达95.5%；其次为毒死蜱，死亡率为84.7%。48h和72h后，除敌敌畏、毒死蜱外，啶虫脒、丁硫克百威、噻虫嗪的防效也显著高于其它处理。另外，吡虫啉SL的防效随时间推移逐渐提高。而甲维盐与清水对照相比一直无显著差异，阿维菌素和高效氯氰菊酯的防效也很低。对敏感种群，24h后效果最好的也是敌敌畏和毒死蜱；48h后除了甲维盐和阿维菌素以外，其余7种药剂的防效均达87%以上，各处理之间无显著差异；72h后，这7种药剂的防效均接近100%。两个种群相比，信丰种群用高效氯氰菊酯、吡虫啉SL、吡虫啉SC、毒死蜱、噻虫嗪、啶虫脒处理24h后校正死亡率显著低于敏感种群，说明信丰种群对这些农药的敏感性都有不同程度的下降。48h和72h后，前4种处理的防效还显著低于敏感种群；另外，72h后阿维菌素和甲维盐处理的信丰种群防效也显著低于敏感种群。信丰种群对高效氯氰菊酯的敏感性下降最为显著，与敏感种群相比死亡率降低了65%~77%，其次为吡虫啉，降低17%~75%，建议该地区暂时停止使用。 |

| Asian citrus psyllid Diaphorina citri K瑄wayama is the vector of citrus Huanglongbing. At present, the prevention and control of this pest is based on chemical insecticides. In order to monitor the effect of chemical control, 9 common pesticides were tested on the adults of Asian citrus psyllid collected from citrus orchards at Xinfeng County, Ganzhou City, Jiangxi Province. The psyllid colony reared on Murraya exotica L. at South China Agricultural University was used as the sensitive population control. The results showed that dichlorvos provided best effect on the field population after 24 h, followed by chlorpyrifos, causing corrected mortality of 95.5% and 84.7% respectively. In addition to these 2 insecticides, the corrected mortalities of acetamiprid, carbosulfan and thiamethoxam were also significantly higher than other insecticides after 48 and 72h. Furthermore, the mortality of imidacloprid SL gradually increased with the passage of time, while emamectin benzoate did not show significant difference compared with water control. The mortalities from avermectin and beta-cypermethrin were also very low. As for sensitive population, the best insecticidal effects were also from dichlorvos and chlorpyrifos after 24 h. After 48 h, the corrected mortalities of all insecticides, except for emamectin benzoate and avermectin were all over 87%, and there were no significant difference among them. After 72 h, the corrected mortalities of these 7 insecticides were all close to 100%. Comparing between the two populations, corrected mortalities of Xinfeng population disposed in beta-cypermethrin, imidacloprid SL, imidacloprid SC, chlorpyrifos, acetamiprid and thiamethoxam were significantly lower than the sensitive population’s after 24 h, demonstrating that the sensitivity of Xinfeng population to these insecticides has decreased. The control effects of the former 4 treatments on Xinfeng population were still significantly lower than sensitive population after 48 and 72 h, and the control effects of avermectin and emamectin benzoate were also significantly lower than control. Among the 5 insecticides, the sensitivity of Xinfeng population to beta-cypermethrin decreased most seriously, followed by imidacloprid, with mortality reduced by 65%~77% and 17%~75% respectively. It is recommended that these 2 insecticides should be stopped using in Xinfeng. |
