Work is underway at Pendleton, OR to find resistant wheat varieties for the Russian wheat aphid. South African researchers have found resistance to be conferred by single, dominant genes in some lines. Of 995 lines evaluated at Pendleton, only 20 had some tolerance to the pest.

USDA tests have shown that predatory insects do a better job of controlling stored grain pests than fumigation, and pose no risk of contamination. New regulations are needed to allow introduction of biocontrol insects into grain bins. These bugs can be easily removed during cleaning, but their levels generally do not get high. Using the bugs before harvest will help eliminate residual pests and add to the prevention of a problem.
