Identification of feeding deterrent/repellent for the brown marmorated stink bug

The brown marmorated stink bug, Halyomorpha halys (Stal) (Hemiptera: Pentatomidae), is an extremely polyphagous pest in Asia and host rang includes plants of economic importance such as pea, soybean, apple, peach, cherry, and various other fruit and ornamental trees.  Damage to crops from H halys in mid-Atlantic States has reached critical levels, especially, caused serious damage to peach and apple crops with some growers loosing over 60 to 100 percent of their crop.  The effectiveness of various insecticide classes to control of H. halys has been tested in laboratory conditions, however, some pesticide application must be conducted by a pest control applicator.  There is no current effective biological control agent available, thus alternative management tools are needed to protect plants.  Feeding deterrents/repellents of H. halys have been identified in the laboratory bioassay and can be immediately used in orchards or other commodity-based fields.  Because they are natural products, there are no environmental pollution concerns as using other synthetic insecticides.  The identified feeding deterrents/repellents can be easily commercialized and used for protecting agricultural crops from H. halys damage in support of ongoing H. halys management programs.
