Resumo: | The present experiment was carried out to study the frequency, collection type (nectar and/or pollen), behaviour of insects on watermelon flowers, Citrullus lanatus var. Crimson sweet, and the effect of these insects on fruit production. The flowers were marked and fruit set was evaluated: 14 female flowers were protected and compared to the same number of unprotected flowers. The most frequent insects were stingless bees Trigona spinipes (48.72%), followed by stingless bees Tetragonisca angustula (15.70%), Africanized honeybees Apis mellifera (9.93%), flies - Diptera (9.30%), wasps - Vespidae (7.70%), ants - Formicidae (5.13%) and butterflies - Lepidoptera (3.52%). T. spinipes visited the flowers from 8 a.m. to 5 p.m. without injuring them and preferred male flowers (82.9%) compared to female ones (17.1%). These bees decreased the frequency in elapsing the day. T. angustula preferred male flowers (85.4%) compared to female ones (14.6%) and showed a peak of nectar hoarding at 9 a.m. and pollen hoarding at 6 p.m. A. mellifera preferred visiting male flowers too (71.0%) compared to female ones (29.0%), showing two peaks of hoarding at 10 a.m. for nectar and 6 p.m. for pollen. Flowers of the covered area, which were not visited by insects, did not produce fruits. |

Crimson sweet, e seu efeito na produção de frutos, tanto em quantidade quanto em qualidade. As flores foram marcadas e a produção foi avaliada: 14 flores femininas foram cobertas com armações revestidas de tecido de náilon para impedir a visita dos insetos e os dados foram comparados a um mesmo número de flores descobertas. Os insetos mais freqüentes nas flores da melancia foram as abelhas irapuás (Trigona spinipes - 48,72%), seguidas das abelhas jataí (Tetragonisca angustula - 15,70%) e africanizada (Apis mellifera - 9,93%), dípteros (9,30%), vespídeos (7,70%), formigas (5,13%) e coleópteros (3,52%). As abelhas irapuás visitaram as flores das 8h às 17h, preferindo as flores masculinas (82,9%). Esta abelha diminuiu sua freqüência no decorrer do dia. A abelha jataí preferiu flores masculinas (85,4%) mostrando um pico de coleta de néctar às 9h e de pólen às 18h. A abelha africanizada preferiu as flores masculinas também (71,0%), mostrando dois picos de freqüência, às 10h para néctar e às 14h para pólen. As flores que foram mantidas cobertas durante a floração não produziram frutos.Universidade Estadual de Maringá2008-03-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/140810.4025/actasciagron.v27i3.1408Acta Scientiarum.
