中文摘要:
目的】 山东省地处我国昆虫南北季节性迁飞的主要通道,明确迁飞性害虫在山东省的迁飞过程和迁飞规律,对于全国迁飞性害虫监测与防控均具有重要意义。【方法】 2018年在山东省14个地区设置监测站点,利用探照灯诱虫器和地面灯诱虫器对迁飞性昆虫进行了实时监测,分析了9月初-10月底迁飞性昆虫的种群动态,首次探讨了昆虫经山东省向南迁飞的种类及迁飞路线。【结果】 诱集到棉铃虫Helicoverpa armigera (Hübner)、玉米螟Ostrinia nubilalis (Hübner)、桃蛀螟Conogethes punctiferalis Guenée、劳氏粘虫Leucania loreyi等重要害虫以及中华通草蛉Chrysoperla sinica、大草蛉Chrysop pallens等天敌。根据迁飞性昆虫种群数量“突增突减”的现象,以及探照灯诱虫器和地面灯诱虫器诱集数量比值,明确了棉铃虫、亚洲玉米螟、桃蛀螟、劳氏粘虫、黄地老虎Agrotis segetum、大地老虎Agrotis tokionis、甜菜夜蛾Spodoptera exigua、斜纹夜蛾Spodoptera litura、银纹夜蛾Ctenoplusia agnata、甘薯天蛾Agrius convolvuli 、瓜绢野螟Diaphania indica、甜菜白带野螟Hymenia recurvalis、黄翅缀叶野螟Botyodes diniasalis (Walker)、豆荚斑螟Limabean podborer、东方蝼蛄Gryllotalpa orientalis、中华通草蛉、大草蛉17种昆虫出现了明显的迁飞过程,这些昆虫由北向南迁飞时,主要途经地点是宁津(25.90%)和济阳(20.81%),其次为庆云(12.31%)、曹县(9.26%)、菏泽(7.09%)、临清(5.47%)。【结论】 经山东省向南迁飞的昆虫种类丰富,主要从山东西部通过。
英文摘要:
[Objectives]  To clarify the migration of migratory pests in Shandong province, which is located on the main north-south insect migration passageway in China, and is therefore important to the monitoring and control of migratory pests in the rest of China. [Methods]  Searchlight-traps and ground light-trap were used to monitor migratory insects from early September to the end of October 2018 at 14 monitoring stations in Shandong province. This is the first investigation of the migration routes of species migrating southward in Shandong province. [Results]  Many important insect pests, such as Helicoverpa armigera, Ostrinia nubilalis, Conogethes punctiferalis, Leucania loreyi, and several of their natural enemies, such as Chrysoperla sinica, Chrysop pallens, were trapped. Based on sudden fluctuations in the numbers of insects trapped by searchlight-traps, and the ratio of insect populations trapped by searchlight-traps and ground light-traps, we found that 17 species undergo obvious migrations in this period, including H. armigera, O. furnacalis, C. punctiferalis, L. loreyi, Agrotis segetum, Agrotis tokionis, Spodoptera exigua, Spodoptera litura, Ctenoplusia agnata, Agrius convolvuli, Diaphania indica, Hymenia recurvalis, Botyodes diniasalis, Limabean pod borer, Gryllotalpa orientalis, Chrysoperla sinica and Chrysop pallens. The main sites of north to south insect migration were Ningjing (25.90%), Jiyang (20.81%), Qingyun (12.31%), Caoxian (9.26%), Heze (7.09%) and Linqing (5.47%). [Conclusion]  Numerous insect species migrate from north to south through Shandong province, mainly through the western part of the province.
