[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.
