Evolução do sistema reprodutivo de formigas da tribo Attini (Hymenoptera : myrmiciane): análise das espermatecas
(Universidade Estadual Paulista (Unesp), 2007-10-04)
A espermateca dos insetos estoca os espermatozóides desde a cópula até a fecundação dos ovos, e consiste de uma bolsa que freqüentemente possui glândulas associadas. Considerações sobre a anatomia, histologia e ultra-estrutura ...
Attractiveness of Different Citrus Pulps to the Leaf-Cutting Ant Atta sexdens rubropilosa (Hymenoptera: Formicidae)
(California State University, 2009-01-01)
The most common control method Uses toxic baits consisted of dehydrated citrus pulp as carrier and attractant. However, the portion of the citrus fruit that is attractive to ants is still Unknown, despite its importance ...
Yeasts associated with nests of the leaf-cutting ant Atta sexdens rubropilosa Forel, 1908
(Kluwer Academic Publ, 1997-03-01)
A total of 137 yeasts associated with the leaf-cutting ant Atta sexdens rubropilosa Forel, 1908 were characterized, being selected 93 for analysis. Twenty four species belonging to seven genera(Candida, Cryptococcus, ...
DECOMPOSITION RATES OF SPENT FUNGAL REFUSE OF ATTA-SEXDENS (HYMENOPTERA, FORMICIDAE) AND IMPLICATIONS FOR ESTIMATING FORAGE INTAKE BY LEAF-CUTTING ANTS
(Gustav Fischer Verlag Jena, 1994-05-01)
Using simulated ceramic refuse chambers, field decomposition studies were performed on the spent fungal refuse of the lead-cutting ant Atta sexdens rubropilosa. Refuse half life was estimated at 40 days, with complete ...
Sites of Defoliation by Atta sexdens rubropilosa (Hymenoptera, Formicidae) in Artificial Plants
(California State University, 2009-01-01)
This study aimed to achieve a better understanding about the foraging behavior of leaf-cutter ant (Atta sexdens rubropilosa Forel) workers with respect to defoliation sites in plants. To accomplish that, artificial plants ...

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 ...
