“…Regarding the floral resource foraged during bee visits (FIGURES 3b and d), in hybrids investigated in the two sites studied, the frequency of visits for nectar collection was higher than for pollen collection, corroborating the observations made by Siqueira et al (2011) and Kiill et al (2012).…”

“…These morphological differences between floral types are important for this crop, because in melon plants, the production of male flowers is higher than the production of hermaphrodite flowers, with sex ratio ranging from 6-19 male flowers to 1 hermaphrodite flower (ABREU et al, 2008;KOUONOM et al, 2009;SIQUEIRA et al, 2011;TSCHOEKE et al, 2015). In this way, although the production of hermaphrodite flowers is lower, they have morphological characteristics that make them more attractive.…”

-Floral morphology and biology are important characteristics for plant-pollinator interactions and may influence the behavior of these agents. This study aimed to determine which floral attributes of different melon hybrids influence this interaction and, consequently, their attractiveness in simultaneous crops. The study was conducted in the region of Petrolina, State of Pernambuco (PE)/Juazeiro, State of Bahia (BA) and Mossoró, State of Rio Grande do Norte (RN), in areas with the following melon hybrids: Yellow type, Piel de Sapo, Cantaloupe and Galia. For studies on floral morphology and biology, hermaphrodites and male flowers of each hybrid were analyzed for their size and nectar chamber size, pollen and nectar production, anthesis time and flower lifespan. Floral visitors were observed simultaneously in hybrids of three types of melon, from 5:00 a.m. to 6:00 p.m., in the two study sites. Evaluations of the corolla diameter and flower height indicated that the hermaphrodite flowers were larger in size than male flowers in all types of melon investigated, in both study sites. As for nectar chamber, male flowers are larger in width, but smaller in height, compared to hermaphrodite flowers. Regarding the volume of nectar, differences were found between floral types for the hybrids evaluated, in the two study sites; the hermaphrodite flowers produced 2-7 times more nectar than male flowers in all studied hybrids. Observations of visits of Apis mellifera to areas with simultaneous flowering of the three types of melon demonstrated differences in the frequency of visits between hybrids, floral type and foraged resource. Flowers of the hybrids Piel de Sapo and Cantaloupe exhibited larger corolla diameter, larger dimensions of the nectar chamber and greater supply of resources for foraging, which could explain the higher number of visits of bees to their flowers in the sites studied.

NA ATRATIVIDADE DE POLINIZADORESRESUMO -A morfologia e a biologia floral são consideradas como características importantes nas interações planta-polinizador e podem influenciar o comportamento desses agentes. O objetivo deste trabalho foi verificar quais os atributos florais de híbridos de diferentes tipos de meloeiro poderiam influenciar nessa interação e, consequentemente, em sua atratividade em cultivos simultâneos. O estudo foi realizado na região de Petrolina-PE/Juazeiro-BA e Mossoró-RN, em áreas com os híbridos de meloeiro do tipo amarelo, pele-de-sapo, cantaloupe e gália. Para o estudo da morfologia e a biologia floral, foram selecionadas flores hermafroditas e masculinas de cada híbrido, que foram avaliadas em relação às suas dimensões e da câmara nectarífera, produção de pólen e de néctar, horário de abertura e tempo de vida da flor. Os visitantes florais foram observados concomitantemente em híbridos de três tipos de meloeiro, no período das 5h às 18h, nos dois locais ...

“…In relation to foraged resource the pollen collection concentrated in the morning and the nectar collection observed during the whole day is in accordance with the pattern observed by Hoz (2007) and Siqueira et al (2011) and indicates that this difference can be related with the constant production of nectar by flowers attracting bees throughout the day.…”

The study was carried out to verify if there are differences in foraging frequency and behavior of Apis mellifera in two melon hybrids (10:00 -'Yellow melon' and Sancho -'Piel de Sapo') in the municipality of Juazeiro, state of Bahia, Brazil. The frequency, behavior of visitors and the floral resource foraged were registered from 5:00 am to 6:00 pm. There was a significant difference in the frequency of visits when comparing hydrids (F = 103.74, p <0.0001), floral type (F = 47.25, p <0.0001) and resource foraged (F = 239.14, p <0.0001). The flowers of Sancho were more attractive to A. mellifera when compared with hybrid 10:00, which may be correlated to the morphology and floral resources available. This could be solved with scaled planting, avoiding the overlapping of flowering of both types.

“…In this research, in all situations of number of hives, there was more visits to hermaphrodite than to male flowers, although the first type is produced in much lower number (1:16 up to19, SIQUEIRA et al, 2011). This preference of bees must be related to the floral resource, since hermaphrodite flowers offer more nectar than male ones.…”
