The pollination services performed by Apis mellifera are essential for the high-quality apple production. The aim of this study was to obtain information about the pollination services used in the municipalities of Vacaria-RS e São Joaquim-SC, the main apple-producing regions in Brazil. Semi-structured interviews were conducted with apple growers and technicians responsible for the orchards during 2013 and 2015. The obtained information was: a) cropping systems; b) use of pollination services; c) number of hives per hectare during flowering; d) renting value of hives; e) mortality of colonies; f) agrochemicals used on flowering; g) presence of native bees on flowering. In Vacaria and São Joaquim, respectively, 70% and 68.6% of the apple growers use the integrated apple production as their production model. The directed pollination is used by 100% and 90.0% of respondents respectively, from which, 80% and 47.1% opt for the hive rent. On average, three hives were used per hectare in both regions. The average cost is U$ 17.52 and U$ 17.74 per hive, respectively. During the flowering period, insecticides and fungicides are used by 100% and 97.2% of the apple growers. The highest mean percentage of mortality of colonies during flowering was reported in Vacaria, 11.8%. Native bees are often found in apple flowers. The development of management strategies for the conservation of domestic and wild pollinators is essential.

O objetivo deste estudo foi obter informações sobre os serviços de polinização utilizados nos municípios Vacaria-RS e São Joaquim-SC, principais regiões produtoras de maçãs no Brasil. Entrevistas presenciais com questionários semiestruturados foram realizadas junto aos maleicultores e técnicos responsáveis pelos pomares, entre 2013 e 2015. As informações obtidas foram: a) sistema de cultivo adotado; b) emprego de serviços de polinização; c) número de colmeias por hectare na floração; d) valor do aluguel de colmeias; e) mortalidade de colônias; f) insumos químicos utilizados na floração; e g) presença de abelhas nativas na floração. Em Vacaria e São Joaquim, 70% e 68,6% dos maleicultores utilizam a produção integrada de maçã como modelo produtivo. A polinização comercial é utilizada por 100% e 90,0% dos entrevistados, respectivamente, dos quais 80% e 47,1% optam pelo aluguel de colmeias. Em média, são utilizadas três colmeias por hectare em ambas as regiões. O custo médio é de R$ 56,60 e R$ 57,30 por colmeia, respectivamente. Durante a floração, agrotóxicos foram utilizados por 100% e 97,2% dos entrevistados. O maior percentual médio de mortalidade de colônias foi relatado em Vacaria, 11,8%. Abelhas nativas são frequentemente observadas na floração. É imprescindível o desenvolvimento de estratégias de manejo para a conservação de polinizadores domésticos e silvestres.

Division of labor among workers is common in insect societies and is thought to be important in their ecological success. In most species, division of labor is based on age (temporal castes), but workers in some ants and termites show morphological specialization for particular tasks (physical castes). Large-headed soldier ants and termites are well-known examples of this specialization. However, until now there has been no equivalent example of physical worker subcastes in social bees or wasps. Here we provide evidence for a physical soldier subcaste in a bee. In the neotropical stingless bee Tetragonisca angustula, nest defense is performed by two groups of guards, one hovering near the nest entrance and the other standing on the wax entrance tube. We show that both types of guards are 30% heavier than foragers and of different shape; foragers have relatively larger heads, whereas guards have larger legs. Low variation within each subcaste results in negligible size overlap between guards and foragers, further indicating that they are distinct physical castes. In addition, workers that remove garbage from the nest are of intermediate size, suggesting that they might represent another unrecognized caste. Guards or soldiers are reared in low but sufficient numbers (1?2% of emerging workers), considering that <1% usually perform this task. When challenged by the obligate robber bee Lestrimelitta limao, an important natural enemy, larger workers were able to fight for longer before being defeated by the much larger robber. This discovery opens up opportunities for the comparative study of physical castes in social insects, including the question of why soldiers appear to be so much rarer in bees than in ants or termites.
