摘要：

为了解浙江省金华市柑橘主要种植区内柑橘黄龙病及媒介昆虫柑橘木虱的发生情况,本研究在金华市5个县市区16个乡镇街道进行柑橘黄龙病和柑橘木虱发生情况调查与采样,调查研究结果如下,采集的210份样品中检测出13份样品携带黄龙病菌,黄龙病菌检出率达6.2%,其中永康市唐先镇样品检出率最高,达20.0%,此外武义县白洋街道,婺城区洋埠镇、罗埠镇,永康市花街镇样品检出率均超过10.0%;通过对黄龙病菌16S rDNA进行特异性扩增,发现克隆后的测序结果与已报道的亚洲柑橘黄龙病菌(Candidatus Liberibacter asiaticus)相似性均在99.5%以上。金华市下辖的兰溪市、婺城区、金东区、武义县及永康市均有柑橘木虱的发生,其中永康市柑橘木虱发生率最高,达到83.3%,兰溪市柑橘木虱发生密度最高,成虫虫口密度为21.0头·株^-1,有虫株率为41.9%。综合黄龙病检测结果与柑橘木虱发生情况表明,金华市下辖的兰溪市、婺城区、武义县和永康市属于黄龙病和柑橘木虱发生重叠区。
