Sugarcane Aphid in Sorghum near San
Angelo
Joel
Webb, EA-IPM Runnels and Tom Green, today has identified sugarcane aphids in
the San Angelo area. This is the nearest
confirmed growing season report of the sugarcane aphid to the High Plains area. The aphid was confirmed as overwintering right
here in Hale County and was found on native Johnson grass in Lubbock, Hale,
& Swisher Counties earlier this spring, but since that time has fallen off
the ‘radar’ with no more colonies found in our area. We assume healthy populations of predators
are to blame for the disappearance of the aphid from our area, but we cannot be
certain. With no native sugarcane aphids
to monitor, we have been and will be watching the migration of the aphid from
the south while anticipating and bracing for their arrival on the High Plains. In the Valley, Coastal Bend, and Hill Country,
the aphid has been an economic pest this year, but reduced in population compared
to recent seasons.
