Wheat Bug
Nysius huttoni
The Wheat Bug (Nysius huttoni) is a pest of wheat, flax, clover, oats, barley, rye and other crops. An enzyme in adult saliva can affect flour protein when milled. Damage of 1% of wheat grains can make the whole crop unsuitable for baking. Surveys were conducted because of the presence of potential host material in Wyoming and high potential for establishment after introduction. Endemic to New Zealand, it has spread through Northern Europe but has not been found in the United States.
The Wheat Bug portion of the Small Grains Commodity Survey is conducted by the Wyoming Pest Detection / CAPS Program. The survey is a visual examination of the host plant. Host plant fields were swept with nets and visually surveyed May through August. Sweep net samples were examined for suspects at ÃÛÑ¿TV.
