| 中文摘要: |
| 在新种柑橘园中栽种柑橘无毒苗，定期监测和防治果园内柑橘木虱Diaphorina citri Kuwayama，防治时期为各新梢萌芽期，重点防治期为早夏梢期和早秋梢期；与此同时，调查柑橘园周围柑橘木虱寄主植物，每年2月下旬、5月上旬、8月下旬和11月下旬定期喷药，清除柑橘园周围寄主植物上的柑橘木虱。结果表明，果园内柑橘木虱和黄龙病均得到有效的控制，果园内柑橘木虱种群数量控制在很低的水平，最高为225头/公顷，最低为0；黄龙病发病率也很低，2008年为8‰，实施该技术后，发病率逐年下降，2012年降低到01‰。 |

| In new citrus orchards, virus-free citrus seedling were planted, the Asian citrus psyllid Diaphorina citri was regularly monitored and controlled during the new shoot sprouting period, especially in the early summer shoot period and early autumn shoot periodMeanwhile, the host plants of citrus psyllid surrounding the citrus orchard were surveyed, and the citrus psyllid on these host plants were eradicated by regularly sprayed chemical pesticides in late February, early May, late August and late November each yearThe results show that, the psyllid and Huanglongbing in citrus orchard were effectively controlledThe Asian citrus psyllid populations in citrus orchard were very low, the largest number of adults was 225 per ha，and Huanglongbing was decreased gradually as well after the practice of this management, from 8‰ in 2008 to 01‰ in 2012 |
