“…Researches in Panamá found that the duration of visits of A. mellifera to melon flowers was strongly related to the floral type, and the longer time recorded in visits to hermaphrodite flowers was attributed to the greater complexity of shape and structure of this floral type (HOZ, 2007). despite the differences in nectar chamber height found in the studied varieties of melon, hermaphrodite and male flowers presented dimensions compatible with the average length of the proboscis of A. mellifera (4.81 ± 0.40mm), as reported by Souza et al (2009). Therefore, this characteristic would not be limiting to the collection of nectar by honeybees and could not explain the differences in attractiveness between the floral types and between the studied hybrids.…”

-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 ...

“…A pequena variação entre as abelhas africanizadas do litoral e sertão indica grande homogeneidade para o padrão de venação das asas anteriores, indicando não ter uma separação de ecótipos entre esses dois ecossistemas. Souza et al (2009) estudando a morfometria de Apis Mellifera da mesorregião do sertão paraibano encontrou em seus resultados dois grupos distintos morfometricamente, o que se assemelha com esse estudo.…”

This study aimed to determine possible differences between populations of Africanized bees in the coastal area and of the sertão of Piauí, as a technique using geometric morphometry. The material analyzed consisted of adult workers of Africanized bees from the coastal region and of the sertão of Piauí. It was used as a comparative reference breeds digital images of the wings of 50 individual's subspecies of European, African, and 45 individuals of Africanized bees coming from Ribeirao Preto in morphometric analyzes. In total we analyzed 645 images of wings. In the morphometric

“…Previous studies indicated morphological variation gradients regarding geographical distribution. Souza et al (2009) showed two different morphometric groups of A. mellifera in northeast Brazil. Nunes (2012) found morphologically differentiated groups of honey bees regarding geographical distribution in five Brazilian macro-regions (North, Northeast, South, Southeastern, and Midwest).…”

Wing morphometrics reveals the migration patterns of Africanized honey bees in Northeast Brazil

Climatic differences can directly affect the population structure of organisms. The Northeastern Brazilian covers an area of about 1.5 million square kilometres, in which the semi-arid part corresponds to approximately 60%. It is probably the most vulnerable region to climatic variations in Brazil. Here, we investigated the variability of Africanized honey bees in different localities from Northeast Brazil during the dry season and the influence of drought periods in morphological variation among populations. Analyses were carried out with data collected by traditional and geometric morphometrics of bees sampled during the dry season and showed a subtle morphological variation in agreement to the climatic pattern. Furthermore, once we added samples collected during the rainy season, we observed a change in its pattern, with a very different result from the same population sampled during drought periods. The geometric morphometrics results emphasized that samples collected during the rainy season in Mossoró would be more similar to bees from humid coastal areas. These results probably reflect the probable dispersion pattern of these bees between humid coastal and semi-arid areas.
