| Studies on nests of the social wasp Polistes (Epicnemius) cinerascens Saussure showed correlation between the size of the comb and thickness of the peduncle, besides of the height of the complete cells and the number of generations produced. The duration of the colony cycle (199.3 days), the number of cells built (102.9) and adults produced (94.2) allowed to establish the rates: 0.5 cells/day, 0.3 adults/day, and 0.8 adults/cell, the % of productive cells/ nest (55.2), and the number of the generations/colony (up to 4 generations). The number of instars was 5; the growing ratio 1.3; the duration of the immature stages was eggs = 13.0 days, larvae = 23.7, pupae = 22.2 and total duration = 58.6 days; and the longevity of adult wasps = 38.3 days. |

| Foram realizadas 100 horas de observação usando o método "scanning sample" para a qualificação e quantificação dos atos comportamentais de rainhas e operárias de quinze colônias de Polistes canadensis canadensis. Foi descrito um repertório comportamental com 28 atos, no qual rainhas executam 19 atos na colônia, enquanto operárias 26, ocorrendo 17 atos em comum entre as duas castas. Dentre esses atos, dois foram exclusivos do repertório de rainhas e nove de operárias. O resultado do teste do qui-quadrado apontou diferenças significativas entre os repertórios das duas castas, sendo que rainhas permanecem mais tempo no ninho e executam com maior freqüência atividades intra-nidais, ligadas à reprodução, enquanto que as operárias executam mais freqüentemente... |

| Considerable importance has been given to nest construction and larval food transport to the nest as a precondition for the eusociality of insects. Most adult hymenopterans feed on liquids, although bees and a few wasps may also feed on pollen. Carrion represents an additional source of protein for some species and they will scavenge for dead animals in the wild. This paper aims at analyzing Hymenoptera visitors on a pig carcass during the process of decomposition, in the summer of 2005 and the winter of 2006 in Brazil, and comparing the results with other studies in the Neotropical region. To our knowledge, this is the first study which described the occurence of Agelaia pallipes, Polybia paulista and Scaptotrigona depilis on decomposing carcasses in... |
