Interpretive Summary:

Technical Abstract: The Suction Trap Network is a set of suction traps currently located in Illinois, Indiana, Iowa, Kansas, Louisiana, Michigan, Minnesota, Missouri, Nebraska, and Wisconsin. The objective of the STN is to monitor aphids of agricultural interest, to detect invasive species, to track the phenology of soybean and Eastern flower thrips (vectors of Soybean Vein Necrosis Virus), and other potential pests of soybean. For Iowa, the flight activity of the total number of aphids collected from 2016 through 2020 varied from one year to another for all the locations but Ames which had a lower density and diversity of aphids than the other locations. Abundant aphid pest species for all locations in Iowa included the bird cherry-oat aphid and the soybean aphid. There was seasonal population dynamics for soybean and Eastern flowers thrips in 2020. The soybean thrips were more abundant than the Eastern flower thrips mostly in Kanawha and Sutherland with peaks occurring in the middle of August and the first week of October.
