Abstract

ABSTRACT: Annonaceae presents great prominence in the world, with high potential in the production of fruit for commercial purposes. Pollination is an extremely important environmental service, both for ecosystems and for agriculture, which is essential for the increase in fruit footprint. The present study aimed to evaluate the richness, behavior and efficiency of the pollinators of the sugar-apple, in the municipality of Belém-Alagoas. 11 visits were carried out in the study area, totaling 40h of sample effort, for the observation of floral visitors in the morning and night periods. To evaluate fruit formation, pollinator efficiency treatments, manual self-pollination (geitonogamia), cross-pollination (manual), and natural pollination (control) were performed. Three species of Coleoptera were observed visiting the flowers of Annona squamosa L. Only 0.5% of the flowers of natural pollination (control) formed fruit, already in the evaluation of the efficiency of pollinators, the conversion occurred of 45% of the flowers in fruits. In Geitonogamia and cross-pollination formed 76% and 96% of the fruits, respectively. Of the animals that were observed interacting with the flowers of Annona squamosa in the municipality, only the beetles behaved as pollinators, because they contacted the reproductive structures of the flowers. The disappearance of pollinators from the cultivation of Annona squamosa, directly affects the formation of the fruits, the culture being dependent on this service. The use of agrochemicals and the absence of native vegetation are the cause in the absence of the pollinators of Annona squamosa.

KEYWORDS: Sugar-apple, pollination, family agriculture.
