The sugarcane aphid (Melanaphis sacchari) emerged as a sorghum (Sorghum bicolor) pest in North America in 2013 and became a concern in sorghum production in Haiti in 2015. Field experiments were conducted in Jonc-Labeille, Haiti in 2018 and 2019 to determine the effects of intercropping sorghum with maize (Zea mays) or pigeon pea (Cajanus cajan) compared to a sorghum monoculture on sugarcane aphid infestations. Additionally, laboratory, greenhouse, and field experiments were conducted in Belle Glade, FL to determine the effects of biological insecticides on sugarcane aphid infestations. Azadirachtin, pyrethrins, Beauveria bassiana strain GHA, Isaria fumosorosea Apopka strain 97, Chromobacterium subtsugae strain PRAA4-1T, Burkholderia spp. strain A396, and vetiver oil were compared to a conventional insecticide, flupyradifurone."
