Resistant varieties, beneficial predators can help producers win sugarcane aphid battle

While sugarcane aphids have been difficult to suppress in past years due to their natural traits and limited insecticide options, a Texas A&M AgriLife Research study shows resistant sorghum varieties and beneficial predators could provide a solution.Dr. Ada Szczepaniec, AgriLife Research entomologist at Amarillo, recently authored "Interactive effects of crop variety, insecticide seed treatment, and planting date on population dynamics of sugarcane aphid and their predators in late-colonized sorghum" in the Crop Protection journal.This research demonstrates that a commercially available resistant sorghum variety provides an adequate protection against this pest in the central High Plains. It also shows aphid predators already present are readily attracted to aphid-infested sorghum, Szczepaniec said.
