| Abstract Honey has different physical and chemical properties because it is produced from the nectar of plants. The present work had the objective of analyzing laboratory tests on honey bee Melipona subnitida D. from Ceará, in comparing them with other honeys from the Northeast Region, making it possible to know better the standards of these honeys, in order to verify their suitability to the Brazilian legislation and contribute to a future more appropriate and specific legislation for the honey of the native bees, since the existing legislation only addresses bee products from Apis mellifera L. Studies were correlated with Fiehe/hydroxymethylfurfural (HMF) in addition to pH/acidity, Lund, lugol, moisture, ash, soluble solids (°Brix) and coloring. For the... |

| In order to conduct a proper risk assessment of pesticides to bees, information is needed in three areas: (i) the toxicity of the pesticide; (ii) the probability of bee exposure to that pesticide; and (iii) the population dynamics of the bee species in question. Information was collected on such factors affecting pesticide risk to (primarily wild) bees in several crops in Brazil, Kenya and The Netherlands. These data were used to construct ?risk profiles? of pesticide use for bees in the studied cropping systems. Data gaps were identified and potential risks of pesticides to bees were compared between the crops. Initially, risk profiling aims to better identify gaps in our present knowledge. In the longer term, the established risk profiles may provide... |

| (Biologia floral de cinco espécies de Passiflora L. (Passifloraceae) em mata semidecídua). O estudo da biologia floral de cinco espécies de Passiflora foi feito em uma mata de planalto em Campinas, São Paulo. Passiflora alata, P. amethystina e P. miersii apresentam flores de cor púrpura a violeta e corona variegada. As flores são diurnas, perfumadas, autoincompatíveis e polinizadas por abelhas de grande porte. Passiflora amethystina e P. miersii diferem de P. alata por apresentarem filamentos livres no opérculo, que em P. alata é horizontal e denticulado. Estas diferenças no opérculo promovem comportamentos característicos das abelhas durante as visitas. Passiflora suberosa possui flores verde-amareladas e opérculo plicado. As flores são diurnas, inodoras,... |

| The bee species of the Apinae, in addition to the thoracic salivary glands, possess a pair of cephalic glands originating as branches of the excretory duct that crosses the head. These glands are known as cephalic salivary or labial cephalic glands. The degree of development of these glands in newly emerged, nurse and forager workers and virgin and egg-laying queens of Apis mellifera Linnaeus, 1758 and Scaptotrigona postica Latreille, 1807 were evaluated by measuring the secretory alveolar units. The area of the secretory alveoli, measured in total gland preparations, was used to evaluate differences in size. In both species, gland size was found to increase progressively from newly emerged workers to foragers and from virgin to egg-laying queens. A... |

| Parasites of adult bees are almost exclusively flies and the most important of them are conopids. This note registers for the first time the association of species of Physocephala (Diptera: Conopidae) with Centris (Heterocentris) analis (Fabricius). From 26 females and nine males of the host species found dead inside trap-nests on the campus of the University of São Paulo, Ribeirão Preto, Brazil, 35 parasitoids were obtained belonging to nine species of Physocephala. The data show that C. analis is a host to several conopid flies, and suggest that such parasitoids can play an important role in population control of this bee species. |
