Danielle Sekula, IPM Agent in Weslaco, is reporting finding small colonies of sugarcane aphids. She said, "My student Alma and I detected sugarcane aphids on commercial sorghum at about the V8 stage down by the river in Hidalgo County. That was on Tuesday, March 21, about 3 weeks earlier than we first found them in a commercial field in 2016. The colonies we found this week were small, containing one winged aphid (alate) and 3 to 5 small nymphs. Sugarcane aphids are barely starting to colonize. But with the current heat and strong winds, the sugarcane aphid may start to populate rapidly and migrate north quickly in our valley sorghum in the next few weeks.
Please start scouting your sorghum diligently and prepare for possible spray applications, if need be."
