| 中文摘要: |
| 为探索枣树嫁接对枣黏虫越冬场所和虫态的影响, 调查了枣树主干、主枝、侧枝嫁接部位、主干绑缚防虫带部位枣黏虫的越冬情况。结果表明, 在10~15年生枣树 (尚未形成老翘皮) 的新嫁接区, 枣黏虫已向新越冬场所转移, 在4个调查部位均有越冬蛹, 以主干防虫带处越冬蛹数最高, 平均达16头左右, 其次为主干和主枝嫁接部位, 平均达6~8头, 越冬蛹存活率均在60%以上。另发现枣黏虫除以蛹越冬外, 在新嫁接处还有越冬幼虫存在, 这些幼虫可能会对枣树的新愈伤组织造成危害。本研究表明枣树栽培模式的改变对枣黏虫的越冬场所和越冬虫态均有一定的影响。 |
| 英文摘要: |
| In order to explore the effects of jujube (10-15 years old, without old bark) grafting on overwintering sites and state of Ancylis sativa, overwintering instars and its survival were investigated at the grafting sites of jujube trunk, main branch, lateral branch and trunk insect-resistant band. The results showed that overwintering A. sativa transferred to new overwintering sites, and the trunk insect-resistant band become the favorite sites of A. sativa with an average of 16 overwintering pupae, followed by the grafting trunk and the main branch sites with an average of 6-8 overwintering pupae. The survival rate of all overwintering pupae was more than 60%. Besides the overwintering pupae, the overwintering larva were found in the new grafting sites and the larva may do harm to the new callus culture of jujube. The results indicated that the cultivation mode of jujube had a certain influence on overwintering sites and stages of A. sativa. |
