Principal component analysis was used to search for relationships among communities of predators (Coccinellidae, Syrphidae, and Chrysopidae), aphids, and environmental conditions in crops of sorghum (Sorghum bicolor (L.) Moench) in 2016, 2017, and 2018. The aphid species collected were Schizaphis graminum (Rondani), Rhopalosiphum maidis (Fitch), and Melanaphis sacchari (Zehntner). M. sacchari was most abundant, with abrupt decrease in abundance over the years. Twelve species of Coccinellidae predators, two Chrysopidae, and 13 of Syrphidae were identified. Principal component analysis revealed a stronger relationship between M. sacchari and predators than weather. The relationship among Hippodamia convergens Guérin-Méneville, Scymnus (Pullus) dozieri Gordon, and M. sacchari was excellent.
