绿盲蝽对不同葡萄品种叶片的危害特性

Damage Characteristics of Apolygus lucorum on Leaves of Different Grape Varieties

为明确绿盲蝽对不同葡萄品种的危害特性,从我国酿酒葡萄和鲜食葡萄主要种植地区之一的秦皇岛市昌黎县选择了9个酿酒葡萄品种和43个鲜食葡萄品种,对叶片受害程度及同一品种不同叶位的受害程度进行调查分析。结果表明:不同品种的受害指数存在显著性差异(P<0.05),酿酒葡萄品种中霞多丽品种的受害程度显著高于其它品种,绿盲蝽对小味儿多品种的危害程度最轻;鲜食葡萄品种中玫瑰香葡萄品种的受害程度显著高于其它品种。同一品种不同叶位被害情况也呈显著性差异(P<0.05),如霞多丽品种第3,第4片叶为害最重,第9,第10片叶为害最轻;玫瑰香葡萄品种第5片叶为害最重,第9,第10片叶为害最轻。

9 wine grape varieties and 43 table grape varieties were selected from Changli County,Qinhuangdao City to study the damage characteristics of Apolygus lucorum to different grape varieties through analyzing the damage degree of leaves and the damage degree of different leaf positions of the same variety.The results showed that there were significant differences in the damage index of different varieties(P<0.05).Chardonnay wine grape had a significantly higher damage degree than other varieties.Apolygus lucorum was the least harmful to Petit Verdot wine grape.The damage degree of Muscat table grape was significantly higher than other varieties.The damage to different leaf positions of the same variety was also significantly different(P<0.05).For example,the 3rd and 4th leaves of Chardonnay were the most damaged,the 9th and 10th leaves were the least damaged.The 5th leaves of Muscat were the most damaged,the 9th and 10th leaves were the least damaged.
