2011 recommended treatments and thresholds for corn and grain sorghum insects. Brief biological sketches of pests included. (PDF Format Only)

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.
