The southern green stink bug, Nezara viridula (L.), and the brown stink bug, Euschistus servus (Say), are common pests in Louisiana agricultural crops including cotton, soybeans, corn and grain sorghum. The objective of this presentation is to point out some visual differences between the two species which are helpful for early field detection.
In Louisiana, southern green stink bugs and brown stink bugs (Figures 1, 2 and 3) have become common pests of corn, cotton, grain sorghum, soybean and wheat. In corn, an infestation can cause injury to the plant from seedling emergence through ear formation and grain development. Seedlings punctured by stink bugs exhibit small holes surrounded by localized dead tissue.
2011 recomended controls and thresholds for soybean insect pests. Brief biological sketches of soybean insect pests are included. Soybeans can be damaged by insects any time from plant emergence until near to harvest in Louisiana. Many kinds of insects feed on leaves, stems, roots, nodules and pods, but only a few require control with insecticides. (PDF Fomat Only)
