摘要: 针对宁夏灵武地区枣园绿盲蝽越冬卵在枣枝的分布特征不明等问题,于2018年3月初采用“Z”字形取样法调查了两块枣园样地绿盲蝽越冬卵在枣枝上的产卵位置,并分析了修剪口处越冬卵的数量及形态特征。结果表明,当年休眠期枝剪口处的平均卵量显著高于枣股及其翘皮,且2年生枝与多年生枝剪口卵量显著高于1年生枝剪口;剪口周皮部的平均卵量显著小于髓心部,但带卵率显著大于髓心部;剪口周皮部的越冬卵长度、饱满度均显著大于髓心部,剪口周皮部与髓心部的越冬卵宽度、瘪卵数均差异不显著。在管理精细无杂草的纯枣园中,休眠期修剪口处的周皮部与髓心部是绿盲蝽产卵越冬的主要场所。据此提出封闭剪口与早春整枝修剪是防治绿盲蝽危害的关键措施。

Abstract: It was largely unknown about the distribution of overwintering eggs of Apolygus lucorum(Meyer-Dür)on the branches of‘Lingwu’jujube orchard in Ningxia region. An investigation on the location of the overwintering eggs of A. lucorum in the two-jujube orchard were carried on by using the method of“Z”type in March 2018,and their number and morphological traits in the pruning wounded position were analyzed. The results showed that the average number of eggs on the current-year branch was significantly greater in the pruning wounded position than in the both mother spur and cracks of old barks;there was significantly higher values in two-year-old and perennial pruning wounded positions than the one-year-old ones;there was significantly lower values located in periderm than in pith,whereas there was significantly higher egg-carrying rate located in the periderm than in pith. The length and plumpness of the overwintering eggs were significantly higher in periderm than in pith,whereas there was no significant difference in width and number of shriveled eggs between the two locations. It was suggested that the overwintering eggs of A. lucorum were mainly located at the dormancy pruning wounded positions,and it was projected observed in the periderm and the pith for their oviposition under well-management jujube orchard. It was concluded that both the closed pruning wounds and early spring pruning residues were the key measures to control the damage of A. lucorum in terms of their distribution.
