为明确山西省太谷地区‘壶瓶枣’枣园绿盲蝽越冬卵分布及粘虫板对绿盲蝽产卵的影响, 对该地区不同管理水平的枣园绿盲蝽越冬场所进行调查, 并结合室内外饲养观察卵孵化规律, 在枣园悬挂黄色粘虫板观察其对绿盲蝽秋季成虫落卵量的影响。结果表明:不同管理水平枣园, 绿盲蝽越冬卵分布场所均以枣树断茬口为主, 其次是修剪口和中年生枣股, 一年生枣股、老年生枣股及翘皮缝也有少量分布; 枣园内外的杂草上均发现有少量绿盲蝽越冬卵, 而在土壤中几乎没有分布; 枣树不同部位卵分布的集中程度不同, 卵粒数由多到少顺序为:断茬口>枣股>修剪口>翘皮缝; 绿盲蝽越冬卵4月中下旬开始孵化, 孵化盛期为4月底到5月初; 秋末, 挂黄色粘虫板可使绿盲蝽越冬卵数量降低42.88%~87.56%。研究结果对‘壶瓶枣’枣园绿盲蝽的防控具有重要指导意义。 |
英文摘要: |
In order to clarify the distribution of the overwintering eggs and the effect of sticky trap on oviposition of Apolygus lucorum in ‘Huping jujube’ orchard in Taigu of Shanxi Province, the overwintering places of A. lucorum in the jujube orchard under different management level were investigated, egg hatching rules were observed by the combination with indoor and outdoor feeding methods, and the effects of yellow sticky trap on egg numbers of A. lucorum autumn adults were observed in jujube orchard. The results show that overwintering eggs mainly distribute at wounds of stubble, followed by pruning wounds and middle-aged mother spur of jujube, only a little distribute at one-year mother, old-aged mother spur of jujube and bark cracks in different management jujube orchards. A small amount of overwintering eggs are found in weeds in jujube orchard, but rarely in soil. The concentration of eggs distribution of A. lucorum is various in different sites of jujube tree, and the egg number was ranked as follows: wounds of stubble>mother spur of jujube>wounds of pruning>cracks of old barks. Overwintering eggs begin to hatch from middle and late April, and the period of hatching peak is from the end of April to the beginning of May. At the end of autumn, sticky yellow boards can reduce the number of overwintering eggs of A. lucorum by 42.88%-87.56%. The results will provide important guiding significance for the prevention and control of A. lucorum in jujube orchard. |
