| 中文摘要:为明确辽宁省苹果蠹蛾Cydia pomonella（Linnaeus）的发生规律，于2014-2016年连续3年对辽宁省彰武县哈尔套镇10个村59个不同梨园采用三角屋胶粘式诱捕器进行了雄成虫数量消长动态的监测，并对幼虫蛀果率、老熟幼虫数量及化蛹行径、蛹期进行调查。结果表明，在辽宁省彰武县，从4月下旬至9月下旬，苹果蠹蛾成虫共有2次发生高峰：第1次为5月下旬，第2次为7月中下旬；苹果蠹蛾在2016年全年内有3次明显的蛀果高峰期：第1次为6月下旬至7月上旬，第2次为8月上旬，第3次为8月下旬。老熟幼虫更趋向于脱果后直接掉落到地上再从地上沿着树干往上爬并在老翘皮下寻找合适位置化蛹；苹果蠹蛾经人工饲养的蛹期为9.95 d。研究表明，苹果蠹蛾在辽宁省彰武县1年发生2代，第1代从5月中旬到9月下旬，越冬代从7月中旬到翌年6月下旬。 |

| Abstract:To determine the occurrence regularity of codling moth Cydia pomonella (Linnaeus) in Liaoning Province, the number of male adults was monitored in three consecutive years (2014-2016) by using triangle adhesive traps in 59 different pear orchards in ten villages of Haertao Town, Zhangwu County, Liaoning Province. The fruit decay rate, the number of mature larvae, pupation, pupal period and life history were also determined. The results showed that there were two occurrence peaks of codling moth adults from late April to late September in Zhangwu County:late May and mid-July to late July. The codling moth had three obvious peaks of fruit decay rate in 2016:late June to early July, early August and late August. The mature larvae tended to fall to the ground and crawl up the tree trunk to pupate in proper position after they escaped from pear fruits. The pupal period was 9.95 days. Two generations of the codling moth occurred per year in Zhangwu County:the first generation occurred from mid-May to late September, and the overwintering generation from mid-July to late June the next year. |
