Electrolytic treatment of wastewater from a fowl slaughterhouse using cast-iron electrodes
(1998-12-01)
A viability study of an electrolytic process for the transformation of organic matter and free sulphide contained in wastewater from a fowl slaughterhouse in order to minimise odours was carried out Cast iron and aluminium ...
The caste system of Coptotermes gestroi (Isoptera: Rhinotermitidae)
(2005-08-04)
Coptotermes gestroi is an oriental species introduced to Brazil and considered, in the São Paulo State area, one of the most economically important pests. Although there are a few works concerning the basic biology of this ...
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 ...
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, ...

Background: The aim of this study was to evaluate the presence of bacteria and fungi on dental plaster casts stored long-term. Methods: Forty-four pairs of dental casts stored since 1980e1981 were used. The material for ...
Caste differentiation pathways in the Neotropical termite Silvestritermes euamignathus (Isoptera: Termitidae)
(2016-07-01)
Termites are hemimetabolous insects that commonly exhibit a bifurcation in post-embryonic development, with the presence of two lines: (i) the nymphal–imaginal line; and (ii) the apterous line. The former comprises the ...
Castes in the neotropical social wasp Leipomeles dorsata (Fabricius) (Hymenoptera: Vespidae): A window for workers achieving a new status in the colony
(2010-01-01)
Morphometric studies performed in several species of Neotropical social wasps from the tribe Epiponini showed that in some species there are marked differences between castes, while other species present highly distinct ...
