          Abstract

          Temporal variation of solitary wasps and bees, nesting frequency, mortality, and parasitism were recorded from a remanent forest in Belo Horizonte, MG, Brazil. Wasps and bees were collected in trap-nests placed in areas with 25, 100, and 400 m², from February to November 2004. The 137 trap-nests collected contained 11 species of wasps and bees. Wasps occupied most nests (75%). Occupation peaks occurred in March (25%) and September (26%); in June, the lowest occupation (2%) was observed. Except for Trypoxylon (Trypargilum) lactitarse Saussure, no significant correlation was found between number of occupied nests, and temperature and rainfall means. In the nests, 48% of the immature specimens died; 13% of the nests were parasitized. Total death and parasitism rates of wasps and bees differed significantly.

          Avaliou-se a variação temporal das freqüências de nidificação de vespas e abelhas solitárias, a mortalidade e o parasitismo associados às suas espécies em um fragmento de mata em Belo Horizonte, MG. Os Hymenoptera foram coletados por meio de ninhos-armadilha dispostos em três tamanhos de área (25, 100 e 400 m²). De fevereiro a novembro de 2004, coletou-se o total de 137 ninhos fundados por 11 espécies de abelhas e vespas. A maioria (75%) foi fundada por vespas. As armadilhas apresentaram picos de ocupação nos meses de março (25%) e setembro (26%). O mês em que ocorreu menor ocupação foi junho (2%). Excetuando-se Trypoxylon (Trypargilum) lactitarse Saussure, não foram observadas correlações significativas entre o número de ninhos ocupados e as médias mensais de temperatura e pluviosidade. O total de 48% dos ninhos apresentou mortalidade de imaturos e 13% deles foram parasitados. As taxas de mortalidade e parasitismo foram diferentes para abelhas e vespas, i.e., ninhos de vespas apresentaram maior mortalidade.

            The Bees of the World

            A comprehensive, worldwide treatment of all groups of bees - 1200 genera and subgenera, including more than 16,000 species. In extensive introductory sections, Charles D. Michener examines the evolution of bees from wasps, the relations of the families of bees to one another, the evolution of bees in relation to that of flowering plants, the nesting behaviour of solitary and social bees, and the structure of immature and adult bees. Drawing on these considerations as well as the fossil record, he speculates on the attributes of the protobee, the common ancestor of all bees. He also cites the major literature on bee biology and describes the need for further research on the systematics and natural history of bees, including their importance as pollinators of crops and natural vegetation.
