Sumario:Spathodea campanulata is an ornamental plant species native to Africa introduced to Brazil whose flowers produce large amounts of nectar that is toxic to insects. The aim of this work was to assess the insecticidal potential of S. campanulata nectar through mortality tests performed on Sitophilus zeamais in Assis, São Paulo State, Brazil. The highest sugar concentrations were recorded in nectar harvested from flowers in the evening. Pure nectar spray treatments showed a control efficiency of 89% of the insect population, which was a statistically significant difference as related to other nectar and control treatments.
