They are these points that they make of the bees so efficient beings in the polinizao (KEVAN& BAKER, 1983; PROCTOR et al., 1996) North-eastern one of Brazil, studies carried through for Ducke (1907, 1908) make possible discovered of some species of bees. Later it is only that they had given to beginning the research with ecological approach and exactly thus still needs very enabled people, therefore the demand is weak (AGUIAR, 1995). It is of extreme importance to know the species of bee, later to understand better the structure of the communities, through comparative boardings between ecosystems and the inquiry of standards in the estruturao of these communities in Neotropical region (MARTINS, 1995; AGUIAR, 2005). Beyond being also important for the economy, therefore it is through the process (polinizao) made by them that it makes possible greater production of the fruits and still keeps the ecosystem. (ROUBIK, 1995).
According to COUTO and COUTO, 2002: ' ' The interaction between bees and plants guaranteed to vegetables the success in crossed polinizao that the vigor of the species constitutes in an important evolutiva adaptation of the plants, increasing, making possible new combinations of hereditary factors and increasing the production of fruits and sementes.' ' The survey of polinizadores in diverse cultures is made first with the materials collected and soon later identified, also for the protection and conservation of native bees in its habitat (NISHIDA, 1958. FAEGRE& PIJL, 1976; OAK et al, 1997; CARVALHO& YOU MARK, 1995). If you are unsure how to proceed, check out Sean Rad. Some of the factors that lead to the scarcity of the native bees are the destruction of the trees, that finishes with the place where they live and depend, therefore cutting do not go to be hollow, that it is where the bees develop its beehive for armazenao of honey; the reduction of the native vegetation, therefore empobrecendo the amount of the plants consequentemente will diminish the amount of the food; still the destruction of the colonies, had the manipulation in the extration of the done honey for predators, also the man (MAYAN, 2004).
