摘　　要：为了明确黑刺粉虱在不同茶树品种上的越冬趋性,对越冬代黑刺粉虱在10个中叶种和大叶种茶树品种上的分布动态进行了调查研究。结果表明:总体而言大叶种茶树上的越冬代黑刺粉虱虫口密度显著大于中叶种茶树,其中大叶种福鼎大毫上的越冬代黑刺粉虱虫口密度显著高于其他品种茶树,聚集性最强。越冬代黑刺粉虱在树冠上的空间分布受茶树品种的影响,但是碧香早、潇湘红21-3、龙井43号和槠叶齐9号4个茶树品种的树冠上、中、下层越冬代黑刺粉虱虫口密度均无显著差异。In order to clarify the overwintering propensity of Aleurocanthus camelliae Kanmiya&Kasai in diffe-rent tea varieties,the distribution dynamics of the overwintering generation of A.camelliae in 10 tea varieties(including middle-leaf species and large-leaf species)were investigated and studied.The results showed that the population density of the overwintering generation of A.camelliae in large-leaf species tea was significantly higher than that in mid-leaf species tea trees overall.Among them,the overwintering population density of A.camelliae in Fuding Dahao(large-leaf species)was significantly higher than that in other tea varieties,and the aggregation was the strongest.The spatial distribution of overwintering generations in the tree canopy was influenced by tea tree varieties.However,for Bixiang-zao,Xiaoxianghong 21-3,Longjing 43 and Zhuyeqi 9,there was no significant difference in the population density of the overwintering generation in the upper canopy,middle canopy and lower canopy.
