Pollination, which is the transport of pollen grains to flower stigma, can be done by insects. Considering the pollination importance, this study aimed to evaluate the abundance of insect pollinators and floral resources on a trail of Parque Municipal Dr. Petrônio Chaves in the city of Ituiutaba-MG. Two methodologies were used to capture insects, the first collected floral visitors in full bloom activity, with plastic bags, from June (2015) to April (2016) and through of pantraps, from September (2017) to February (2018). The flowers were collected and identified to evaluate the floral resources. With plastic bags, 247 insects were collected, the ants (83.8%) were found in the flowers, as well as other non-insects pollinators. Most of the flowers were of Rubiaceae and Bignoniaceae, they had red and violet tubular morphology, pollen and nectar, but there are no odor. The yellow pantraps were more attractive to Diptera and the blues collected more Hymenoptera. The presence of pollinators was verified, but these were not found visiting the flowers, whose visitors were not good pollinators.
