- W48744103 abstract "Podium angustifrons e uma especie de vespa solitaria que nidifica em cavidades pre-existentes, com distribuicao na Guiana Francesa, Bolivia e Brasil. O objetivo deste estudo foi investigar a biologia de nidificacao desta especie, discutindo aspectos de sua historia de vida. Para captura dos ninhos de P. angustifrons, foram instaladas ninhos-armadilha de madeira no Parque Municipal das Araucarias, Guarapuava (PR), Brasil, de Janeiro 2003 ate Abril de 2009. Foram coletados 29 ninhos, durante todos os meses quentes. Os ninhos nao apresentaram celulas vestibulares e intercalares, seus fechamentos sao constituidos por material vegetal mascado, seguido de barro misturado a materiais orgânicos, revestidos por resina, podendo ter uma camada de liquens. As celulas foram aprovisionadas com diferentes especies de baratas silvestres (Chorisoneura sp, Riata sp e Helgaia sp) em estagio de ninfa e/ou adulto. A maioria das pre-pupas entrou em diapausa no inverno com tempo de desenvolvimento de 187 a 283 dias para as femeas e 180 a 283 dias para machos. Ocorreu mortalidade em 41,66% das celulas aprovisionadas, sendo 33,33% causado por falha de desenvolvimento e 8,33% por cleptoparasitas da familia Chrysididae.%%%%Podium angustifrons is a species of solitary wasp which nests in pre-existing cavities, with neotropical distribution in French Guyana, Bolivia and Brazil. The aim of this study was to investigate the nesting biology of Podium angustifrons, discussing aspects of their life history. To capture the nests of P. angustifrons, wooden trap-nests were installed in the Parque Municipal das Araucarias, Guarapuava (PR), Brazil, from January 2003 to April 2009. A total of 29 nests were collected, all during the warmer months. These showed no vestibular and intercalary cells, and their closures were made up of chewed plants and mud mixed with organic materials and resin-coated surfaces, sometimes showing a layer of lichens. The cells were provisioned with various wild species of cockroaches (Chorisoneura sp, Riata sp and Helgaia sp) in the nymph stage and / or adults. The sex ratio was 4.6 females per male, significantly higher that the expected 1:1. Most pre-pupae entered diapause in winter with development time ranging from 187 to 283 days for females and 180 to 283 days for males. Deaths occurred in 41.66% of cells provisioned, 33.33% were attributed to faulty development and 8.33% to Chrysididae." @default.
