Sugarcane Aphid (SCA) Current 2015 Distribution Map(s)
Dr. Robert Bowling, Extension Entomologist in Corpus Christi, has spent several weeks looking for sugarcane aphids this winter on Johnsongrass and sorghum from the Rio Grand Valley and even over to the San Angelo area. He has assembled maps that contain individual county records of when he found aphids and a composite map for the start of 2015 that are located at Texas Sugarcane Aphid News . As diligent as Dr. Bowling has been looking for the sugarcane aphid, we know there are still many counties that have not been checked and aphids may start to become active on Johnsongrass and any of the sorghum related plants as temperatures rise and plants start growing. Anytime you come across sugarcane aphids in counties that have not been reported for your county, please contact someone on the personal contact list of the Texas Sugarcane Aphid News, and/or collect some aphids in a ziplock bag or another container, let a contact person look at the aphids or take the aphids to your local county extension office.
Sugarcane Aphid Overwintering Site - Hale County, TX
Mr. Blayne Reed, Extension Agent - IPM for Floyd, Hale, and Swisher counties and Dr. Pat Porter, Extension Entomologist - District 2, monitored the overwintering Johnsongrass site in Hale County for winter survival of sugarcane aphids. They found no surviving sugarcane aphids at the site yesterday. Last November the site was infested with sugarcane aphids and had a thriving population. At the site temperature recorders were used to monitor hourly the temperature at the soil surface and at a 4.5 inch depth below the soil surface. Details about the temperature data can be found at Texas Sugarcane Aphid News . This provides good evidence that sugarcane aphids did not successfully overwinter, at least from Hale Center to the Northern Texas High Plains. Many thanks are extended to Blayne and Pat for seizing the opportunity to monitor sugarcane aphids winter survival.
