This survey aimed at describing the interactions of floral visitors and Davilla kunthii A. St.-Hil. as well as characteristics of its reproductive biology in Itacoatiara, state of Amazonas, Brazil. Tests of the breeding system were performed. The guild of visitors was described according to richness, abundance, relative frequency and constancy. The breeding system tests indicated that D. kunthii is self-compatible. The pollination system was characterized as generalist, with 39 visitor species, from three different orders. Bees were the main group of pollinators, thus some behavioural aspects were described. Th e period of highest foraging activity was between 7 and 10 am. Some species presented agonistic and monopolistic behaviour. Given the behaviour and... |

Inspite of Etythrina species exhibit morphologic attributes for adaptation to pollination by nectarivorous birds mentioned in the literature, E. speciosa is pollinated by lots of bees (Apinae and Meliponinae) which show a great urban occurrence. Systems of E. speciosa floral reproduction, fenology, diversity, frequency and constancy of insects visiting at different hours and flowering periods were studied. E. speciosa is Biocompatible, but xenogamy is the predominant system of reproduction. A large diversity of insects visiting the inflorescences was observed, with predominance of bees. The bee species showed a higher frequency: Apis mellifera Linnaeus, 1758 (45,0 %), Trigona spinipes (Fabricius, 1793) (28,6%), Trigona hyalinata (Lepeletier, 1836) (12,2 %)... |

Studies were carried out with Lagerstroemia speciosa Pers. on floral reproductive systems, diversity and constancy of visiting insects at different hours of day, the behaviour of these insects at the flowers and the influence of these environmental factors in relation to their visits. The fenology, anthesis and others particularity of this vegetal species was studied. A great diversity of insects was verified visiting the flowers with the predominance of bees. The most frequent and constant species encountered were: Nannotrigona testaceicornis (Lepeletier, 1836) (40,2%), Tetragonisca angustula (Latreille, 1811) (16,9%), Apis mellifera Linnaeus, 1758 (11,8%), Plebeia droryana (Friese, 1900) (9,1 %) e Exomalopsis fulvofasciata (Smith, 1879) (8,5%).
