Rumors of Sugarcane Aphid Resistance and Adaptation to Corn Are Unsubstantiated

Dr. Ed Bynum has addressed some unsubstantiated rumors flying around the High Plains; 1) that sugarcane aphid has become resistant to insecticides in Mexico and 2) that it is now able to develop on corn and is damaging corn in Mexico. I tried to address this last topic in my post last week, but Dr. Bynum has provided more detail on both issues in his newsletter post today.

The bottom line is that there is no evidence of insecticide resistance and no evidence that the aphid can damage corn.
