Abstract:
[Objectives] Shandong province is an important pathway for the north-south migration
of many insect species in China. Understanding the community structure of
migratory insects in Shandong is therefore important for identifying migratory
insect species and predicting their population dynamics. [Methods] 14 monitoring sites were established in
Shandong province and searchlight and ground light-traps deployed on each site
to monitor insects from September to October 2018. [Results] A total of 408
insect species (12 orders and 54 families) were identified in 14 areas. Search
light trapping resulted in a total of 388 insect species (12 orders and
45 families) being identified, whereas ground-light trapping identified 365
insect species (11 orders and 46 families). The main orders captured in
searchlight traps were the Lepidoptera (79.12%),
Coleoptera (9.42%), Orthoptera (8.14%) and Neuroptera (2.26%), and the main orders captured by
ground-light traps were the Lepidoptera (68.84%),
Coleoptera (23.46%), Hymenoptera (3.69%), Orthoptera (1.50%) and Hemiptera
(2.26%). Searchlight traps captured more insects than ground light-traps. [Conclusion] These results reveal the structure and diversity of the Shandong
insect community, and confirm the migratory behavior of many important insect
species in this province.
