Background: When the natural pollinator's declines, beekeeping can contribute to the pollination services, assuring crop yields, and can also be used to strengthen the livelihoods through commercialization to increase economic revenue. Methods:A farmers' survey and field experiment were conducted on 2011 to assess the economics of beekeeping as pollination management practices adopted by the farmers of Chitwan district, Nepal. Samples of 75 respondents from the list of beekeeper farmers of Chitwan district were selected randomly. Information was obtained from individual respondents through a pretested questionnaire and group discussion. Furthermore, to assess the benefit of bee pollination 15 experimental plots were selected to see the effect of bee pollination on mustard crop yield.Results: From the study, the gross income (rupees/hives), productivity (rupees/man-day), average cost (rupees/ hives), and gross benefit (rupees/hives) as a result of keeping bees were found to be 4475.23, 1506.30, 2526.66, and 1948.57, respectively. The benefit-cost ratio of beekeeping was found to be significantly higher, at 1.8. The contribution of the bee pollination on the mustard crop production was found significantly higher than that on the mustard production without the insect pollination. Conclusions:This research finding will provide the new ways of thinking on the relationship between beekeeping and their importance on the crop production. The pollination shortage due to pollinator declines can be mitigated through the beekeeping which helps to uplift the sustainable livelihoods of the farmers through income generation.

“…Pollination by insects, especially bees, is essential to many crops, for instance apple tree, avocado, melon, passion fruit and pear (GIANNINI et al, 2015). For melon, studies focused on pollination were developed in different countries, showing that this plant depends on Apis mellifera to ensure productivity (SOUSA et al, 2009(SOUSA et al, , 2012.…”

-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. Index terms: anthesis, Cucurbitaceae, nectar, pollen, floral resources. AVALIAÇÃO DE CARACTERÍSTICAS FLORAIS DE HÍBRIDOS DE MELOEIRO (Cucumis melo L.) 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 ...

“…Thus, they need to visit many flowers and consequently act as effective pollinators. In fact, honeybees are considered the most important pollinators of agricultural crops (Witter et al, 2014;Giannini et al, 2015aGiannini et al, , 2015bSousa et al, 2016). An example is melon (Cucumis melo), which depends entirely on pollinating agents for fruit production (Giannini et al, 2015b).…”

This study aimed to analyze the details of collection of floral resources (pollen and nectar) by honeybees (Apis mellifera) on male and hermaphrodite flowers of melon (Cucumis melo). The experiments were conducted in areas located at Embrapa Semiárido and Embrapa Produtos e Mercado, Petrolina, state of Pernambuco, in November and December 2011, with crop of a hybrid yellow 10/00 F1 melon. Honeybee colonies housed in Langstroth hives, uniform concerning the number of individuals and brood area were used. The four experimental areas (0.5 ha each), received respectively 0, 1, 2 and 3 hives, from the first day on which the hermaphrodite flowers appeared to the end of the flowering period of the melon crop. The results showed that the bees visited more the hermaphrodite than the male flowers, in order to collect the resources (pollen and nectar), in all areas where honeybee hives were placed. In general, independently from the number of hives, the resource most collected was nectar. Pollen collection occurred mainly at the first hours of the morning, while nectar was collected throughout the day.
