Resumo: | 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. |

A polinização é um serviço ambiental de extrema importância, tanto para os ecossistemas quanto para a agricultura, essencial para o aumento no pegamento dos frutos. Com o presente estudo objetivou-se avaliar a riqueza, comportamento e a eficiência dos polinizadores da pinha, no município de Belém – Alagoas. Foram realizadas 11 visitas na área de estudo, totalizando 40h de esforço amostral, para a observação de visitantes florais nos períodos matutinos e noturnos. Para avaliar a formação de frutos, foram realizados os tratamentos de eficiência de polinizador, autopolinização manual (geitonogamia), polinização cruzada (manual) além da polinização natural (controle). Foram observadas três espécies de coleópteros visitando as flores de Annona squamosa L. Apenas 0,5% das flores da polinização natural (controle) formaram frutos, já na avaliação da eficiência dos polinizadores, ocorreu conversão de 45% das flores em frutos. Na geitonogamia e polinização cruzada formaram 76% e 96% dos frutos, respectivamente. Dos animais que foram observados interagindo com as flores da Annona squamosa no município, apenas os besouros se comportaram como polinizadores, pois contataram as estruturas reprodutivas das flores. O desaparecimento dos polinizadores dos cultivos da Annona squamosa, afeta diretamente a formação dos frutos, sendo a cultura dependente deste serviço. A utilização de agroquímicos e a ausência da vegetação nativa são a causa na ausência dos polinizadores da Annona squamosa.
