| 中文摘要: |
| 柑桔木虱( Diaphorina citri Kuwayam.)是果园柑橘黄龙病(huanglongbing,HLB)主要传播途径,明确果园柑桔木虱扩散规律,就掌握了柑橘黄龙病传播蔓延趋势。2016年3月—2017年5月在广西金秀县桐木镇一个具有特殊条件的柑橘园开展自然条件下柑桔木虱种群扩散规律的调研。本研究结果与现有国内外相关报道有明显差异性,柑桔木虱传入新果园,刚开始时形成“中心虫株”,然后向外扩散；风是自然条件下影响柑桔木虱种群扩散的主要因子,柑桔木虱扩散与风具有明显正相关,柑桔木虱扩散范围、趋势与风的吹向基本吻合,呈现以“中心虫株”为头部的慧星扩散形状；无台风异常天气影响下,柑桔木虱种群一年自然扩散距离约为105米。 |
| 英文摘要: |
| Citrus psyllids (Diaphorina citri Kuwayam) is the main transmission route of citrus huanglongbing (HLB) in the orchard. By clarifying the law of the spread of citrus psyllids in the orchard, the spreading trend of citrus HLB has been mastered. From March 2016 to May 2017, a citrus orchard with special conditions in Tongmu town, Jinxiu county, Guangxi province was used to investigate the populations diffusion law of citrus psyllids under natural conditions. The results of this study were significantly different from the existing reports at home and abroad. The citrus psyllids were introduced into the new orchard, which formed a “central of citrus psyllids” at the beginning and then spread out; wind was the main factor affecting the population spread of citrus psyllids under natural conditions. The citrus psyllids diffusion had a significant positive correlation with the wind, and the citrus psyllids diffusion range and trend were basically consistent with the wind blowing direction, showing the "central of citrus psyllids" as the head of the comet diffusion shape; In the absence of abnormal weather such as a typhoon, the natural diffusion distance of citrus psyllids population was about 105 meters a year. |
