O cubiu ( Solanum sessiliflorum Dunal) (Solanaceae) e originario da regiao Amazonica. Suas propriedades alimentares, medicinais e agronomicas tem despertado o interesse de pesquisadores desde 1970. No entanto, estudos sobre insetos em plantas tanto de ocorrencia natural como de cultivos sao escassos. O objetivo deste trabalho foi realizar um levantamento da ocorrencia de insetos e  caracterizar os danos aparentes aos cultivos de cubiu localizados em Benjamin Constant, no Alto Solimoes, Amazonas, Brasil. Foram encontradas 51 especies de insetos adultos distribuidas em 22 familias e sete ordens. Hymenoptera, Hemiptera e Coleoptera congregam juntas 82,35% das especies encontradas neste estudo. Hemiptera e Coleoptera sao as ordens com maior numero de familias, oito e cinco, respectivamente; enquanto a familia Formicidae (Hymenoptera) tem  o  maior numero de especies (11). Foram registradas 18 especies de insetos fitofagos, 10 pertencentes a ordem Coleoptera e oito a Hemiptera. O maior numero de familias foi registrado para a ordem Hemiptera com seis, para Coleoptera identificou-se apenas tres. Os Coleoptera da especie Epicauta pestifera Werner (Meloidae) constituem a principal praga do cultivo de cubiu em Benjamin Constant, pois seu ataque em reboleira e capaz de destruir varias plantas em um unico dia e exterminar plantios em poucas semanas. Outros fitofagos dos generos Colaspis e Cerotoma , ambos Chrysomelidae, ao consumirem o tecido foliar expoem as plantas ao ataque de microrganismos e reduzem a area  fotossintetica. Enquanto que Edessa rufomarginata De Geer (Pentatomidae, Hemiptera) causa danos diretos e indiretos e merece atencao durante todo o ciclo de producao. Entomofauna associated to cultivation of Cubiu (Solanum sessiliflorum Dunal) in Benjamin Constant city, Amazonas, Brazil Abstract. Cubiu ( Solanum sessiliflorum Dunal, Solanaceae) is originally from Amazon region and its dietary, medicinal and agronomic properties sparked the interest of researchers since 1970. The studies about insects on cubiu plants both of natural occurrence as well as in cultivations, is scarce. This study aims to relate the visitor insect of cubiu plants, with emphasis to the phytophagous species. We found 51 species of the mature insect, distributed among 22 families and seven orders. Hymenoptera, Hemiptera and Coleoptera represent together 82.35% of the species found in this study. Coleoptera and Hemiptera are the orders with larger number of families, eight and five, respectively, while Formicidae (Hymenoptera) is the family with the largest number of species (11). We recorded 18 species of phytophagous insects, ten belong to the order Coleoptera and eight to the order Hemiptera. However, the largest number of families was recorded to the order Hemiptera with six, while Coleoptera has only three. The species of beetles Epicauta pestifera Werner (Meloidae) constitute the main pest of the cultivation of cubiu in Benjamin Constant, because the attack in agglomerates may destroy many plants in just one day and exterminate the plantation within weeks. Other genus of phytophagous such as Colaspis and Cerotoma , both Chrysomelidae, consumes foliar tissues, exposing the plants to the attack of microorganisms, which may compromise the photosynthetic capacity of the plant. Edessa rufomarginata De  Geer (Pentatomidae, Hemiptera) causes direct and indirect damages and deserves attention throughout the production cycle.
