Sugarcane aphid in grain sorghum The sugarcane aphid, which can be a devastating pest of grain sorghum, was found infesting sorghum in Arkansas in 2014. While it has been present in the U.S. for some time as a pest of sugarcane, it has only been documented in sorghum at economically damaging levels in the U.S. since 2013. Little information is available on the best management practices for this insect in sorghum, and most of the insecticides labeled for use in sorghum are ineffective. We are collaborating with other researchers in Arkansas and throughout the affected region to develop management recommendations for sugarcane aphid. Early efforts will focus on developing an economic threshold, evaluating insecticides and application methods for chemical control, and determining the impact of cultural practices such as planting date and variety on sugarcane aphid populations.
