    • 摘要:
      目的  明确滴灌施药防治柑橘木虱Diaphorina citri Kuwayama的可行性，为田间控制柑橘黄龙病传播提供新的手段。
      方法  通过室内模拟滴灌施用噻虫胺，测定了噻虫胺在土壤中的分布以及柑橘叶片中含量，研究了滴灌施药对柑橘木虱防治效果。通过田间试验，检测分析了柑橘叶片中噻虫胺含量。
      结果  在室内条件下，一次滴灌施药对柑橘木虱的防治效果可长达4个月；噻虫胺在土壤中以滴头为起始点在土壤中呈半圆形迁移分布，当柑橘叶片中噻虫胺质量分数大于0.64 mg·kg–1时，对柑橘木虱的防治效果均高于80%。田间试验表明，在药后7~63 d柑橘上部叶片中噻虫胺的质量分数大于0.64 mg·kg–1。
      结论  滴灌施用噻虫胺能有效防治柑橘木虱，是田间控制柑橘黄龙病传播的有效手段。

       

      Abstract:
      Objective  To study the control effect of clothianidin on citrus psyllid(Diaphorina citri) under drip irrigation, and provide a new way for controlling Huanglongbing (HLB) spread.
      Method  An indoor simulation drip irrigation experiment was conducted for clothianidin. The distribution of clothianidin in soil and the content in citrus leaves were tested, and the clothianidin efficacy was studied under laboratory condition. The content of clothianidin in citrus leaves was detected and analyzed in field experiment.
      Result  The control effect of single drip irrigation could be as long as four months in greenhouse. The migration distribution of clothianidin was a semicircle with a drop head as a starting point in soil, and the control effects of D. citri were more than 80% when clothianidin contents of citrus leaves were greater than 0.64 mg·kg–1. Under field condition, the contents of clothianidin in upper leaves were also greater than 0.64 mg·kg–1 from 7 to 63 days after applying clothianidin.
      Conclusion  Clothianidin application through a drip irrigation system exhibits excellent efficacy against citrus psyllid, which provides an effective measure for prevention and control of HLB.
