In the normal course of a growing season, insect and mite pests of wheat and sorghum sometimes develop into areawide economic threats quickly without the knowledge of insect complexes that develop in these crops and how they interact to produce pest problems. ARS in Stillwater, OK, continuing efforts in areawide surveys of aphid species in wheat and sorghum production areas sometimes encounter new or occasional pests that could potentially develop into a primary pest. The recent increase in canola acreage throughout the Central Great Plains may also have influenced pest complexes in wheat and sorghum. Our objective is to survey, identify, estimate economic impact, and prioritize insect pests as they are developing so that short-term and possibly long-term management support can be developed. During our bi-annual survey for aphid biotypes in sorghum and wheat, we will 1) sample wheat and sorghum to identify insect pest complexes and relative abundance over a period of several years, and 2) develop short-term management plans after they have been identified.
