Mimosa tenuiflora (Willd.) Poir. (Mimosaceae) is a xerophilous plant which is very common in degraded areas in the Brazilian semi-arid region, including areas of beekeeping. The ingestion of leaves from M. tenuiflora by ruminants is responsible for malformations. Chemical analyses of this plant revealed that it contains several secondary compounds including three triterpenoidal saponins, designated Mimonosides A–C, four flavones, five flavanones and four chalcones. Several plant species contain secondary compounds in nectar and pollen that could be toxic to pollinators, including bees. Experimental approaches are necessary to identify plant species that produce pollen that is toxic to bees. The present study aimed to determine the toxic potential of M. tenuiflora (Willd.) Poir. (Mimosaceae) pollen to Africanized honey bees (Apis mellifera L.).(AU)
