XYLOPIA SERICEA A. ST.-HILL. (ANNONACEAE), UMA ESPÉCIE NATIVA POLINIZADA POR THRIPS (THYSANOPTERA)?
Keywords:
beetle, entomophily, flowering, phenology, protogynyAbstract
Beetles are widely reported as the main pollinators of the robust, fleshy flowers of Annonaceae, although other studies highlight the participation of other insects in pollination. In this study, we investigate the pollinators of Xylopia sericea, a multi-purpose native tree, and whether flowering and fruiting are related to climatic variables, from February-2008 to October-2009. Xylopia sericea is exclusively dependent on pollinators for fruit formation, and exhibits protogynous, large, fleshy, white, chamber-like flowers suggest pollination by beetles. But it was the thrips Frankliniella spp., the visitors with pollinator behavior, contacting fertile parts and with pollen attached to the body. Flowering is annual and more synchronous than fruiting, with intermediate synchrony and non-seasonality. Our results add to the growing lacking literature that reports the importance and participation of thrips in the mixed pollination of other Xylopia species.
