Abstract

The reproductive period, flower visitors and predispersal hazards of an Ipomoea species were estudied in 1989 and 1990 at the "Horto Botânico", UFSC. Ipomoea sp. showed peak of flower production in March and peak of fructification in May. Bees, and secondarily, moths were the most frequent flower visitors. Augochlora essex and Augochlora sp. (Hymenoptera: Halictidae) seem to be the effective pollinators. The greatest mortality of reproductive structures was evidenced in buds (64%, n=634) and flowers (50%, n=227). The mortality rates varied durings the reproductive period. The larva of a Diptera: Lonchaeidae occurred in 17% of fruits (n=3961) and damaged 15% (n=7690) of the seeds produced. A dilution effect in the rate of predation was observed in peaks of fructification. Fruits with a greater number of seeds were proportionaly more attacked by the Diptera. Malformation was founded in 9% of seeds, being more frequently in fruits with 3 and 4 seeds.
