Observations On The Seasonal Abundance Of Sorghum Midge, Anthony Zukoff
Kansas Agricultural Experiment Station Research Reports
Sorghum midge,Stenodiplosis sorghicola(Coquillett), is a major pest of sorghum production worldwide. Midge larvae develop within the sorghum spikelet protected from predation and chemical control. Feeding by larvae prevents grain development resulting in varying degrees of blank heads. Historically, sorghum midge has been considered a minor pest in Kansas. In recent years, significant midge infestations have been documented in several locations of the southwest and southeast portions of the state. Some basic information on sorghum midge seasonality in Kansas will help to refine some management recommendations if this pest becomes more prevalent. Sorghum midges were recovered from samples taken …

Integrating cover crops (CCs) in dryland crop production in the semiarid central Great Plains (CGP) can provide several ecosystem benefits. However, CC adoption has been slow in the CGP because CCs utilize water that otherwise would be available for the subsequent cash crop. Grazing CCs can provide economic benefits to offset revenue loss associated with decreased crop yields when CCs are grown ahead of a cash crop. Field experiments were conducted from 2015 through 2022 to quantify effects of grazing CCs on soil bulk density, aggregate stability, and chemical properties across western Kansas. At the Kansas State University HB Ranch …
