Trap-nest occupation by solitary wasps and bees (Hymenoptera: Aculeata) in a forest urban remanent
Provedor de dados: Neotropical Entomology
Autores: Loyola,Rafael D.; Martins,Rogério P.
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...

The flowering-visiting bees at the ecological station of the Universidade Federal de Minas Gerais, Belo Horizonte, MG, Brazil
Provedor de dados: Neotropical Entomology
Autores: Antonini,Yasmine; Martins,Rogério P.
The richness and the composition of bee species at the ecological station of the Universidade Federal de Minas Gerais, Campus Pampulha, Belo Horizonte, MG, Brazil, was recorded from January to December 1996. The bee fauna of the ecological station is rich (98 species) in low-density populations species (350 individuals). The composition of the bee fauna is seasonal (Q = 29.35, df = 11, P &lt; 0.002), however the composition in flowering plants showed no seasonality (Q = 17.30, df = 11, P &lt; 0,099). The bee species visited 23 flowering plant species from 11 families. Asteraceae (111 individuals in 53 species) and Convolvulaceae (88 individuals in 26 species) were the most visited families. There was a positive relation between bee abundance and the number...

An overview of proximate factors affecting the nesting behavior of solitary wasps and bees (Hymenoptera: Aculeata) in preexisting cavities in wood
Provedor de dados: Neotropical Entomology
Autores: Morato,Elder F.; Martins,Rogério P.
Guilds of Aculeate solitary wasps and bees that nest in preexisting cavities in wood are important components of terrestrial ecosystems because they engage in several ecological interactions (e.g. predation and pollination) with other species of plants and animals. Spatial and temporal variations in richness and abundance of solitary wasps and bees can be related to changes in environmental structure and in the diversity of other groups of organisms. The nesting period of these Aculeata is their most critical life cycle stage. Females of solitary wasp and bee species invest relatively more time constructing and provisioning their nests than do females of social species. Differently from species that nest in the soil or construct exposed nests, the main...

Small-scale area effect on species richness and nesting occupancy of cavity-nesting bees and wasps
Provedor de dados: Revista Brasileira de Entomologia
Autores: Loyola,Rafael D.; Martins,Rogério P.
Small-scale area effect on species richness and nesting occupancy of cavity-nesting bees and wasps. The research was conducted in an urban forest remnant in southeast Brazil. We tested the predictions of the following hypotheses: (1) larger areas present higher species richness of bees and wasps, (2) solitary bees and wasps occupy more nests in larger areas, (3) rare species occupy more nests in smaller areas. We sampled Aculeate bees and wasps using trap nests from February to November 2004. We placed trap nests in sampling units (SU) with different size (25, 100 and 400 m²) located in 6 ha of secondary mesophytic forest. One hundred and thirty-seven trap nests were occupied by seven species of bees and four species of wasps. We found an increase in wasp,...

Does predator benefits prey? Commensalism between Corynoneura Winnertz (Diptera, Chironomidae) and Corydalus Latreille (Megaloptera, Corydalidae) in Southeastern Brazil
Provedor de dados: Zoologia
Autores: Callisto,Marcos; Goulart,Michael D.C.; Moreno,Pablo; Martins,Rogério P.
Commensalism between Corydalus Latreille, 1802 (Megaloptera, Corydalidae) and Corynoneura Winnertz, 1846 (Diptera, Chironomidae, Orthocladiinae) larvae was recorded in Indaiá stream, at 1,380 m a.s.l. (Parque Nacional da Serra do Cipó, 19º-20ºS, 43º-44ºW) and in the headwaters of São Francisco river, at 1,300-1,700 m a.s.l. (Parque Nacional da Serra da Canastra, 20º00'-20º30'S, 46º15'-47º00'W), in Minas Gerais state, Brazil. Seventy eight Corydalus larvae (range 22-88 mm) were sampled: 61 in the Indaiá stream and 17 in other two streams. Twelve Corydalus larvae (22-79 mm) in the Indaiá stream and three out of 15 larvae in the headwaters of São Francisco river (38-50 mm) had Corynoneura, larvae and pupae on their gills (3rd to 6th) and a few larvae attached...

A estrutura da guilda de abelhas e vespas visitantes florais de Waltheria americana L. (Sterculiaceae)
Provedor de dados: Anais da Sociedade Entomológica do Brasil
Autores: Macedo,João F.; Martins,Rogério P.
A fenologia floral de Waltheria americana L. (Sterculiaceae) e o número de espécies de angiospermas floridas foram quantificados em dois locais do Campus Pampulha da Universidade Federal de Minas Gerais em Belo Horizonte, Estação Ecológica (EE) e Prefeitura (PR). O objetivo foi avaliar a importância de W. americana como fornecedora de pólen e néctar para uma guilda de vespas e abelhas visitantes. Na estação chuvosa o número de espécies de angiospermas floridas foi maior que na estação seca, mas apresentou diferença significativa apenas na PR. Todavia, em ambas estações, nos dois locais, houve uma correlação positiva entre o número de flores em W. americana e o número de outras espécies floridas. Na PR o número de flores em W. americana foi...

Potencial da erva daninha Waltheria americana (Sterculiaceae) no manejo integrado de pragas e polinizadores: visitas de abelhas e vespas
Provedor de dados: Anais da Sociedade Entomológica do Brasil
Autores: Macedo,João F.; Martins,Rogério P.
A quantificação anual da disponibilidade de flores de Waltheria americana, da riqueza em espécies e da taxa de visitação de abelhas e vespas às suas flores, permitiu avaliar o potencial dessa invasora para os programas de manejo integrado de pragas e de polinizadores. O estudo foi conduzido em dois locais do Campus da Universidade Federal de Minas Gerais - UFMG (Estação Ecológica e Prefeitura). Em cada local foram registrados mensalmente a produção de flores em 20 indivíduos desta planta, o número de espécies e de visitas de abelhas e vespas às suas flores. Trinta e sete espécies de abelhas e 72 espécies de vespas visitaram as flores de W. americana nos dois locais. A riqueza e o número de visitas de abelhas correlacionaram-se positiva e significativamente...
