          Abstract

          Este trabalho tem como objetivo a identificação dos insetos visitantes e polinizadores das flores do "dendê" Elaeis guineensis Jacq., e do "caiaué" Elaeis oleifera (H.B.K) Cortés, atráves de coletas em locais e horários diferentes, quando as inflorescências masculinas das plantas encontravam-se em plena antese. Um total de 159 insetos foram observados tendo sido constatado dentre os diversos tipos de visitantes, os meliponídeos: Trigona sp. ("dendê" e "caiaué"), Apis mellifera adansonni e Partamona sp. ("dendê"). Constatou-se ainda a presença de uma quantidade razoável de insetos da família Curculionidae do gênero Elaeidobius, que voavam em torno das inflorescências, sendo evidente a sua participação na polinização das espécies estudadas. Além disso, verificou-se a presença de larvas de um coléoptero da família lycidae, junto as inflorescências das plantas.

          Translated abstract

          This identifies insects visiting and/or pollinating the flowers of the study "African Oil Palm" Elaeis guineensis Jacq. and the "Brazilian Oil Palm" Elaeis oleifera (H.B.K.) Cortés. Insects were collected at different times of day at different locations, when the male inflorescences were at full anthesis. A total of 159 individual insects were collected including, among others, Meliponid bees: Trigona spp. (on African and Brazilian Oil Palms), Apis mellifera adansonii and Partamona sp. (on African Oil Palm). Also observed were a considerable number of insects in genus Elaeidobius (family Curculionidae) flying about the inflorescence, indicating that they also play a role in the pollination of both palm species. Beetle larvae in the family Lycidae were also noted on the plant inflorescences.
