Sweet potato (Ipomoea batatas (L.) Lam.) is a plant potentially used as food in underdevelopedcountries and although it is easy to be planted and managed, many factors, like insects, may limit itsproductivity. Usually, aphids attack cabbage (Brassica sylvestris (L.) Mill.) Mill.), negatively influencingon its development and survival. The aphid species observed were Brevicoryne brassicae and Myzuspersicae (both Hemiptera: Aphididae). In this study was found that these species co-occur and showpotential to cause damage also on sweet potato plants in Brazil. So, they have to be considered inIntegrated Pest Management - IPM to sweet potato crop.A batata-doce (Ipomoea batatas (L.) Lam.) é uma planta de grande potencial alimentar empaíses subdesenvolvidos e, embora seja de fácil cultivo e manejo, vários fatores podem limitar suaprodutividade, dentre eles, insetos pragas. Comumente, pulgões atacam couve (Brassica sylvestris(L.) Mill., influenciando negativamente no seu desenvolvimento e sobrevivência. As espécies depulgões observadas foram Brevicoryne brassicae (L.) e Myzus persicae (Sulzer) (ambos Hemiptera:Aphididae). Neste estudo foi observado que estas espécies de pulgões coexistem e tambémapresentam grande potencial para causarem danos em plantas de batata-doce cultivadas noBrasil. Desta forma, sugere-se a inclusão dessas espécies de pulgões no programa de ManejoIntegrado de Pragas - MIP da cultura de batata-doce. Sweet potato (Ipomoea batatas (L.)
