Impact and management of the invasive “Kudzu bug,” Megacopta cribraria (Hemiptera: Plataspidae), in soybeans

Since its initial discovery in Georgia in fall of 2009, the distribution and population densities of the invasive plataspid Megacopta cribraria (Fabricius) have increased dramatically in the southeastern United States. This insect readily uses soybeans as both a feeding and reproductive host and has the potential to reduce soybean yields. Due to its recent introduction, management options are still being developed and refined. We examined the relationship between M. cribraria density and soybean yield and quality. In addition, we evaluated treatment thresholds in the soybean maturity groups that are typically grown in the affected region and observed the spatial dynamics of this insect within soybean fields. Our findings will allow soybean producers to better understand and manage this emerging pest.
