Home respiratory polygraphy management is similarly effective to polysomnography, with a substantially lower cost. Therefore, polysomnography is not necessary for most patients with suspected sleep apnea. This finding could change established clinical practice, with a clear economic benefit.

-Nests of Centris vittata were obtained from trap-nests at Santa Carlota Farm, Cajuru, SP, Brazil. The bees nested in bamboo canes ranging from 8.5 to 24.7 cm in length and from 0.9 to 1.9 cm in diameter. The bees constructed their nests with a mixture of soil and an oily substance. Completed nests had 1-8 urn-shaped cells arranged in a linear series, separated by a space filled with loose soil. The nest plugs resembled the bottoms of cells and were externally covered with an oily material. In some cases they were also covered with an another yellowish, sticky substance of unknown origin. The innermost cells of the nests produced females and the outermost cells males, resulting in proterandry. Females were significantly larger than males, and no dimorphism in males was found. Nests were parasitized by the megachilid bee, Coelioxys sp., the bombyliid fly, Anthrax sp. and by meloid beetles. C. vittata nested exclusively in the hot and wet season (September-April), producing at least two generations. © Inra/DIB/AGIB/Elsevier, Paris nesting biology / trap-nest / Centris vittata / Apidae / Brazil

Ninhos de Monobia angulosa Saussure foram obtidos em ninhos armadilhas, na Fazenda Santa Cariota, Cajuru, SP (n=10) e na Estação Ecológica de Jatai, Luís Antônio, SP (n=3). As vespas nidificaram em gomos de bambu que variaram de 158 a 194 mm no comprimento e de 9,5 a 15 mm no diâmetro interno. Os ninhos consistiram de uma série linear de células, variando de 1 a 6, separadas por partições de barro, seguidas ou não por célula vestibular e fechamento, também de barro, construído na entrada do tubo ou mais internamente a ela. Células intercalares foram observadas em 33,3% dos ninhos. As células de cria foram aprovisionadas com lagartas previamente paralizadas e a oviposição foi realizada no teto da célula. Foram produzidas mais fêmeas do que machos, com as fêmeas sendo criadas nas células distais. Tanto o tamanho das fêmeas como o comprimento das células de onde elas emergiram, foram significantemente maiores que os dos machos. Os inimigos naturais foram: Chrysis intrincata Dahibom (Chrysididae), Anthrax sp. (Bombyliidae) e moscas Tachinidae. M. angulosa apresentou, pelo menos, duas gerações por ano, ambas presentes na estação quente e chuvosa.

ABSTRACT. Three nests of Euglossa (Glossura) annectans Dressler, 1982 were obtained from trap nests at Serra do Japi, Jundiai, Sao Paulo State, Brazil. The bees nested in bamboo cane (one nest) and in wooden-boxes (two nests). SolitalY (two cases) and pleometrotic (one case) foundations were observed. Two nests were re-used once by two females working in each of them. Re-using females that shared the nests were of the same generation and each built, provisioned and oviposited in her own cells, characterizing a communal association. The brood development period was related to climatic conditions. Natural enemies included Anthrax oedipus oedipus Fabricius, 1805 (Bombyliidae), Coelioxys sp. (Megachilidae) and Meli/lobia sp. (Eulophidae).
