“…Wooden pieces measured 25x25x130 mm and had 11 cm-deep canals with 6, 9, and 12 mm diameter. Trapnest sizes in this study are similar to those in other studies (Morato & Campos 2000, Morato 2001a. Ten wooden pieces of each canal diameter were randomly arranged as trap-nest blocks.…”

“…Bawa et al (1985) reported that bigger bees are more important pollinators when flowers are located in the canopy. In the Central Amazon region, bees occupied more trap-nests located between 15 m and 8 m high than those at 1.5 m (Morato 2001a). This result may be due to a larger availability of floral resources in the canopy (Roubik et al 1982).…”

Neotropical Entomology 35(1): 041-048 (2006) Ocupação de Ninhos-Armadilha por Espécies de Vespas e Abelhas Solitárias (Hymenoptera: Aculeata) em um ). 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. PALAVRAS-CHAVE: Nidificação, mortalidade, parasitismo, Trypoxylon lactitarse, Auplopus militarisABSTRACT -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 m 2 , 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.

“…This variation, however, must be interpreted cautiously because, in addition to the potential diversity of species in the study area (ALVES-DOS-SANTOS 2003), the results can be affected by different man-made nesting materials (BOSCH 1995), trapnest diameter (VANDENBERG 1995), height of trap-nests in relation to ground level (MORATO 2001), exposure of trap-nests to sun (FRANKIE et al 1988), availabity of natural preexisting cavities , and by the period of sampling. Irrespective of these variables, some general patterns has emerged from the studies made.…”

More recently, trap-nesting bees and wasps have been used in researches designed to evaluate the habitat quality (FRANKIE et al 1998, TSCHARNTKE et al 1998, the effects of habitat fragmentation and of the landscape complexity on community composition and predator-prey interactions (MORATO & CAMPOS 2000, MORATO 2001, STEFFAN-DEWENTER 2002, KRUESS & TSCHARNTKE 2002 asil. asil.…”

Trap-nesting bees (Hymenoptera, Apoidea) in areas of dry semideciduous forest and caatinga, Bahia, Brazil

ABSTRACT. In this study were examined the species richness and seasonal abundance of cavity-nesting bees in areas of dry semi-deciduous forest and caatinga in the State of Bahia, Brazil. Sampling was done employing two types of trap-nests: bamboo canes and tubes made of black cardboard with dimensions of either 58 x 6 mm or 105 x 8 mm. The traps were inspected once a month. One hundred and forty-six nests of 11 bee species were collected in the forest, and 121 nests of seven species were collected in the caatinga. Five species of cleptoparasitic bees were also reared from these nests. The highest nesting frequencies occurred in the wet season in both areas. Nests parasitism was important only for Centris tarsata Smith, 1874, and was higher at the caatinga site than in the forest. The mortality of pre-emergent adults was high, especially in C. tarsata, Tetrapedia diversipes Klug, 1810 and Euglossa cordata (Linnaeus, 1758). Information on the number of cells per nest, the size, shape, and arrangement of brood cells in the nests, as well as the number of adults produced and the number of generations per year are also presented. Species richness, temporal patterns of nesting, and percentage of parasitism were compared with other habitats.

“…Data on communities of trap-nesting bees and wasps and their natural enemies have been used in research on habitat quality (Frankie et al, 1998;Tscharntke et al, 1998), the effects of habitat fragmentation and of landscape complexity on community composition and predatory-prey interactions (Morato and Campos, 2000;Morato, 2001;Steffan-Dewenter, 2002;Kruess and Tscharntke, 2002;Klein et al, 2006;Tylianakis et al, 2006) and how urban environments can support such insects (Tommasi et al, 2004;Zanette et al, 2005).…”

ABsTRACT. We studied the community ecology of trap-nesting bees in two forest fragments of the State of São Paulo, Brazil, during two years, utilizing bamboo canes and tubes made of black cardboard as trap nests. The traps were inspected once a month with an otoscope. One hundred and fifteen nests were obtained at Estação Ecológica de Paulo de Faria, Paulo de Faria (EEPF). These included nine species belonging to five genera and two families. At Santa Cecília Farm (SCF), 12 species belonging to seven genera and three families built 392 nests. Natural enemies reared from nests of both areas included Hymenoptera, Diptera and Coleoptera. Species richness was similar between the areas but the communities differed considerably in species composition. The higher diversity found at EEPF was due to more even distribution of the species. No difference was observed between the numbers of nests built in each year in each area. Although the species richness was lower in the cool/dry season of both years at SCF, and in the first year at EEPF, the nesting frequencies did not differ between seasons for both the overall community but for each of the most abundant species. No annual fluctuation in the frequencies of nesting was observed. As temperature and precipitation were not found to be significantly different between the two years of study in each area, we concluded that climatic stability resulted in population stability.
