Management and within-field spatial distribution of Megacopta cribraria (Hemiptera: Plataspidae) in soybeans

Since its initial discovery in Georgia in fall of 2009, the “kudzu bug” Megacopta cribraria (Fabricius) has expanded rapidly into neighboring states, including South Carolina.  This insect readily uses soybeans as both a feeding and reproductive host and has been shown to significantly reduce soybean yields in multiple field experiments. It is imperative to develop scientifically validated management recommendations for this insect as it continues to expand its range.  In addition to the impact of M. cribraria on soybean yield and quality, we examined the spatial dynamics of this insect within soybean fields and evaluated treatment thresholds for timing insecticide applications.  This information will better prepare affected soybean growers to successfully manage this invasive pest.
