“…2, Nogueira-Neto 2002) could be enough. In addition, currently only few estimates are available of the number of sex alleles present in managed Melipona populations (Kerr 1987;Aidar and Kerr 2001;Carvalho 2001), and none of these studies have considered the genetic consequences of prolongued breeding of stingless bee colonies from a limited stock.…”

Stingless bees play an important ecological role as pollinators of many wild plant species in the tropics and have significant potential for the pollination of agricultural crops. Nevertheless, conservation efforts as well as commercial breeding programmes require better guidelines on the amount of genetic variation that is needed to maintain viable populations. In this context, we carried out a long-term genetic study on the stingless bee Melipona scutellaris to evaluate the population viability consequences of prolonged breeding from a small number of founder colonies. In particular, it was artificially imposed a genetic bottleneck by setting up a population starting from only two founder colonies, and continued breeding from it for a period of over 10 years in a location outside its natural area of occurrence. We show that despite a great reduction in the number of alleles present at both neutral microsatellite loci and the sex-determining locus relative to its natural source population, and an increased frequency in the production of sterile diploid males, the genetically impoverished population could be successfully bred and maintained for at least 10 years. This shows that in stingless bees, breeding from a small stock of colonies may have less severe consequences than previously suspected.In addition, we provide a simulation model to determine the number of colonies that are needed to maintain a certain number of sex alleles in a population, thereby providing useful guidelines for stingless bee breeding and conservation efforts.

“…Recent studies are proving that honey has good effects on human health. The honey of Tetragonisca angustula angustula shows bactericidal action against Escherichia coli (Migula, 1895) and Staphilococcus aureus Rosenbach, 1884 (Aidar 2002). Park et al (2000) have discovered anticancer and anti-HIV activities in ethanolic extracts of propolis of Apis mellifera L., 1758 collected from different parts of Brazil.…”

Insects and the substances extracted from them have been used as medicinal resources by human cultures all over the world. Besides medicine, these organisms have also played mystical and magical roles in the treatment of several illnesses in a range of cultures. Science has already proven the existence of immunological, analgesic, antibacterial, diuretic, anesthetic, and antirheumatic properties in the bodies of insects. Several authors have surveyed the therapeutic potential of insects, either recording traditional medical practices or employing insects and their products at the laboratory and/or clinical level. Thus, insects seem to constitute an almost inexhaustible source for pharmacological research. Chemical studies are needed to discover which biologically active compounds are actually present within insect bodies. The therapeutic potential of insects represents a significant contribution to the debate on biodiversity conservation, as well as opening perspectives for the economic and cultural valorization of animals traditionally regarded as useless. Their use needs to be at a sustainable level to avoid overexploitation.
