| The survival of social wasp species depends on the success in founding new nests. These species can use plant species with different specific characteristics for nesting, with nest architecture varying according to the habits of those plant species. The nesting of social wasps in natural environments was studied in the period from October 2005 to September 2007 inthe rio das Mortes riparian forest, municipal district of Barroso, Minas Gerais State, Brazil, with the objective of evaluating the different types of plant substrate used by social wasps for nesting, and to investigate whether there is a relationship between nest construction type and the habits of plant species. A total of 171 colonies of social wasps belonging to 29 species were recorded, which... |

| Melipona mondury Smith 1863 is an important stingless bee species pollinator and honey/pollen producer, but threatened by fragmentation of habitats throughout its range. This article presents the identification and partial characterization of nesting substrates, bionomic including population features of M. mondury by comparing data between nest architecture of natural beehive and boxes colonies. Nineteen colonies (13 in boxes and six in beehives) were analyzed with regards to substrate nesting, nest characteristics (e.g. length and width of the combs, height and diameter of the pollen and honey jar) and bee population. The average volume and diameter of the trunks cavities used for nesting of M.mondury were18.4 L and 15.8 cm; the average number of combs... |

| The phylogeny of the Stenogastrinae wasps is still under discussion and their systematic incomplete. In the present work we used geometric morphometrics, a technique based on a rigorous statistical assessment of shape, to compare the forewings of fifteen species of Stenogastrinae wasps belonging to four different genera to ascertain whether this approach may be used as a reliable method in the study of the taxonomy of the group. The results show that the wing vein junctions can be diagnostic for both genus and species identification. For the first time in this subfamily, we propose a phylogenetic classification of the species based on wing morphology that largely agrees with the cladistic data available at genus level and reflects the differences among... |

| We examined the hypotheses that the empty combs of Polybia occidentalis Olivier (Hymenoptera: Vespidae) nest insulate the inside of the nest. To examine this hypotheses, two kinds of temperature measurements were carried out: 1) with the outer comb of the nest intact (Control) and 2) removed (Treatment), using a large and a small nest. In the large nest, the daily nest temperatures (outer part, Tn1; inner part, Tn2) in Control were lower by 0.6°C (Tn1) and 1.2°C (Tn2) than those in Treatment, because of a higher ambient temperature (Ta) throughout temperature assessment in Treatment. However, the excess temperature (Tn - Ta) in Control was higher than that in Treatment. The value was higher by 0.7°C at Tn1 and 0.1°C at Tn2. In the small nest, the excess... |
