| 中文摘要: |
| 柑橘木虱Diaphorina citri Kuwayama是黄龙病的传播媒介, 快速、有效防治这种害虫是综合防控黄龙病的关键。目前, 其防治措施主要依赖化学农药。为了了解化学农药对柑橘木虱的田间防治效果, 本文以广东省博罗县柑橘木虱田间种群为测试对象, 以华南农业大学昆虫生态研究室饲养的种群为敏感对照, 室内测定了13种常用药剂推荐浓度对柑橘木虱的防治效果。结果表明, 24 h后77.5%敌敌畏EC和5%啶虫脒EC对田间种群的效果最好, 柑橘木虱死亡率分别为93.3%和90%, 48 h后两种药剂处理的死亡率已达100%; 48 h后, 350 g/L吡虫啉SC处理的死亡率也达93.3%; 72 h后, 20%丁硫克百威EC、30%噻虫嗪SC、12%高氯·毒死蜱EC、45%毒死蜱EC、2.5%高效氯氟氰菊酯EW处理的死亡率也达90%以上。两个种群相比, 所有药剂在相同时间对敏感种群的防治效果都高于田间种群。其中, 用20%甲氰菊酯EC、30%噻虫嗪SC、45%毒死蜱EC、25 g/L联苯菊酯EC、99%矿物油EC等5种药剂处理, 24 h后田间种群的校正死亡率显著低于敏感种群; 48 h后除上述药剂外, 4.5%高效氯氰菊酯ME处理的校正死亡率也显著低于敏感种群。72 h后, 4.5%高效氯氰菊酯ME、25 g/L联苯菊酯EC、99%矿物油EC处理的校正死亡率依然显著低于敏感种群。说明田间种群对以上药剂的敏感性有不同程度的下降。此外发现, 采用此测定方法22.4%螺虫乙酯SC对田间种群和敏感种群的防治效果均不理想。 |
| 英文摘要: |
| The Asian citrus psyllid (ACP), Diaphorina citri Kuwayama is the major vector of Huanglongbing (HLB). Effective control of population of ACP is the key strategy in the integrated management of HLB. At present, the control of psyllid population is based on chemical insecticides. In order to determine the effect of the chemicals, 13 common pesticides were tested on the adult psyllid collected from citrus orchards in Boluo, Guangdong province. Psyllids reared on orange jasmine, Murraya paniculata (L.) Jack. at South China Agricultural University was used as the sensitive population control. The results showed that dichlorvos 77.5% EC and acetamiprid 5% EC were the best treatments for the field population after 24 h, causing mortality of 93.3% and 90%, respectively, and both reached 100% after 48 h. After 48 h, the mortality of imidacloprid 350 g/L SC also increased to 93.3%. After 72 h, the mortalities of carbosulfan 20% EC, thiamethoxam 30% SC, beta cypermethrin·chlorpyrifos 12% EC, chlorpyrifos 45% EC and lambda cyhalothrin 2.5% EW were also over 90%. All insecticides showed better control effect on the sensitive population than the field population. Compared with the sensitive population, the corrected mortality of the field population treated with fenpropathrin 20% EC, thiamethoxam 30% SC, chlorpyrifos 45% EC, bifenthrin 25 g/L EC and 0.5% mineral oil were significantly lower than that of the sensitive population after 24 h. After 48 h, the corrected mortality of beta cypermethrin 4.5% ME was also significantly lower than that of the sensitive population besides the above insecticides. After 72 h, the corrected mortality of beta cypermethrin 4.5% ME, bifenthrin 25 g/L EC and 0.5% mineral oil remained significantly lower than that of the sensitive population, indicating that the sensibility of D. citri to these pesticides has decreased. In addition, it was found that spirotetramat 22.4% SC was not effective on D. citri adults with this indoor detection method. |
