(Maney PublishingLeedsInglaterra, 2003)
Caste flexibility and variation according to the colony cycle in the swarm-founding wasp, Parachartergus fraternus (Gribodo) (Hymenoptera : Vespidae : Epiponini)
(Kansas Entomological Soc, 2004-10-01)
Differences between castes and related aspects in Parachartegus fraternus (Gribodo) have been studied in various stages of the colony cycle. Five colonies from three colony development stages (namely, pre-emergence, ...
An analysis of brass casting parameter process using sand casting mold

Morphological caste differences in the neotropical swarm-founding polistine wasp, Brachygastra lecheguana (Hymenoptera : Vespidae, Polistinae, Epiponini)
(California State University, 2000-01-01)
Morphological caste differences and ovary conditions were analyzed in colony of Brachygastra lecheguana. The results indicate the presence of individuals with ovary development but uninseminated (intermediates). In addition, ...
Non-allometric caste differences in Agelaia vicina (Hymenoptera, Vespidae, Epiponini)
(1998-12-01)
Non-allometric and clear-cut caste dimorphism were found in two colonies of the social wasp Agelaia vicina. Such type of allometry was previously recorded in the Epiponini and its origin is pre-imaginally determined as in ...

Morphohistochemical characterization of the perivisceral fat body in royal and worker female castes in different ages of Atta sexdens rubropilosa ants (Hymenoptera, Formicidae)
(2006-04-21)
The morphohistochemical study of the fat body in royal and worker castes of Atta sexdens rubropilosa revealed that this tissue is made up of trophocytes and oenocytes, trophocytes being the cells with cytoplasmic inclusions ...
Porous ceramics obtained by slip/starch casting consolidation method (SSCC)
(2017-01-01)
Slip/starch casting consolidation (SSCC) is a technique for obtaining porous ceramics, which joins the forming process by starch consolidation with the slip casting method. In this work, a slip which contains ceramic ...
