Abstract

Last year, the widespread outbreak of soybean gall midge took many farmers and entomologists by surprise. There was significant field edge injury and economic loss in at least 65 counties in Iowa, Nebraska, Minnesota, and South Dakota. A small team organized a concerted effort to learn more about the life cycle, biology and management of soybean gall midge in 2019. The first step was to establish emergence cages in various habitat types to better understand where they overwinter. We used the “corn rootworm” style traps to collect adults emerging from the ground. A series of traps in Iowa, Nebraska and South Dakota have been monitored for several weeks this spring (Figure 1).
