“…Xylocopa bees utilize pollen as food (Viana et al 2002) and M. guianensis is a plant with abundant pollen. In addition, Xylocopa are efficient pollination agents, mainly for plants such as Mouriri with poricidal anthers (Buchmann 1983).…”

Mouriri guianensis is a Brazilian endemic plant species distributed throughout the Amazon forest, Caatinga, Mata Atlântica and Cerrado domains, extending northward into Venezuela. The aim of this study was to describe the flowering phenology, floral biology and visitors associated with M. guianensis, highlighting the crepuscular bee species Megalopta amoena. Mouriri guianensis flowers from September to March. The flowering, the details of floral biology and the activities of floral visitors were observed for ten individual plants in December 2013, January-March 2014, September-December 2014 and JanuaryMarch 2015. The flowering peaks occurred in December 2013 and in November-December 2014. Bees were collected in January and February 2015. A total of 86 individuals belonging to six bee species were recorded visiting the flowers, with Xylocopa cearensis making more than one-half of the visits (60%), followed by Melipona subnitida and Megalopta amoena with 21.17% and 9.41% of the visits, respectively. The visitors showed activity peaks between 5:00 and 6:00 AM (66.27%). Buzz pollination was their predominant behavior. Megalopta amoena used its jaws to open the pore and the anther gland. Melipona subnitida used parts of the glands to seal the entrance to the colony. The visitors, except for Augochlopsis sp. and Trigona sp., are pollinators of M. guianensis. Plants having an extended anthesis can attract visitors both day and night. In this study, we present an example of a crepuscular pollination system. We suggest that blooming at twilight is a strategy used by the plant to escape unsuitable visitors. KEYWORDS: Pollination, insect-plant interaction, floral oil, crepuscular foraging. Um total de 86 indivíduos de seis espécies de abelhas foi registrado visitando as flores com Xylocopa cearensis realizando a maioria das visitas (60%), seguida por Melipona subnitida e Megalopta amoena com 21,17% e 9,41%, respectivamente. Os visitantes mostraram picos de atividade entre 5:00 -6:00 h (66,27%). O comportamento predominante foi o de vibração. Megalopta amoena utilizou suas mandíbulas para romper os poros da antera e glândula. Melipona subnitida utilizou partes das glândulas para a vedação da entrada da colônia. Os visitantes, a exceção de Augochlopsis sp. e Trigona sp., são polinizadores de M. guianensis. Plantas com longos períodos de antese podem atrair visitantes diurnos e noturnos. Aqui demonstramos um exemplo de sistema de polinização crepuscular, sugerindo que o fato florir durante o crepúsculo é uma estratégia da planta para escapar de visitantes inoportunos. PALAVRAS-CHAVE: Polinização, interação inseto-planta, óleo floral, forrageamento crepuscular.

ABSTRACT(Nectar production and bee visits in two cultivated species of Passifl ora L. (Passifl oraceae)). Pollinator activity is affected by resource availability. Flowers that produce more nectar are visited more, which results in a greater fruit set. Th e eff ect of nectar production on pollinator activity was tested in two cultivated species of passion fruit, Passifl ora alata Curtis and Passifl ora edulis Sims, in Morretes, Paraná. Flower buds were bagged and the accumulated nectar of fl owers was collected hourly. Th e volume and concentration of nectar of P. alata increased during anthesis, which was associated with rising temperatures. Th e volume of nectar of P. edulis increased during the diurnal period of anthesis, falling aft er 6 pm. Th e nectar concentration was constant during anthesis. Th e visitation rate of Xylocopa frontalis (Olivier) was constant for P. alata (1.7 visits/100fl owers/hour) and for P. edulis (6.6 visits/100fl owers/hour). Th e visitation rate of Bombus morio (Swederus) for P. alata was 5.8 visits/100fl owers/hour, and was higher at the beginning of anthesis. Th e constant rate of visits by X. frontalis may be associated to the continuous nectar production by both species of passionfl ower. Since both species are xenogamous, the maintenance of visits during anthesis may favor pollen fl ow among the individuals assuring good crop production.

This study contributes to the knowledge about the diversity of bees belonging to the genus Xylocopa Latreille, 1802 of the São Paulo State through a compilation of taxonomic and biological information. Identification keys are presented for the four subgenera (Dasyxylocopa Hurd & Moure, 1963; Neoxylocopa Michener, 1954; Schonnherria Lepeletier, 1841 and Stenoxylocopa Hurd & Moure, 1960) and for the 22 species recorded for the state, beyond the available data on its biology, plants visited and geographic occurrence.
