Research ArticleOpen accessIn the author namesMorpho-physiological Differences of the Spermatheca of Attini Ants (Hymenoptera: Myrmicinae)Gabriela Ortiz, Maria Izabel Camargo-MathiasThe insect's spermatheca store the spermatozoa from the time of copulation until the fertilization of the eggs and consists of a sac, usually associated to glands. The ant species Atta laevigata, Atta sexdens sexdens, Atta sexdens piriventris, Acromyrmex coronatus and Cyphomyrmex muelleri are considered pests, as they cause economics losses to several crops. The spermatheca of these species were examined … …American Journal of Agricultural and Biological Sciences, Vol. 1, Issue 4 · 31 Dec 2006 · 7,588 accessesView PDFCite
Research ArticleOpen accessIn the author namesAnalysis of the Differential Gene Expression, by the DD-RTPCR Technique, Of Workers Atta sexdens rubropilosa Mandibular Glands (Hymenoptera: Formicidae)Lorena Favaro Pavon, Maria Izabel Camargo Mathias, Flávio Meirelles, Maurício Bacci JúniorThe DD-RTPCR technique is becoming more efficient nowadays to isolate and characterize genes differentially expressed among cells, tissues or individuals, being used here, for the first time in the study of mandibular glands of minina and media workers and soldiers of the ant species Atta sexdens rubropilosa. The expression profile of bands (transcripts), obtained in the present study, permitted the … …American Journal of Agricultural and Biological Sciences, Vol. 1, Issue 2 · 30 Jun 2006 · 7,846 accessesView PDFCite
Research ArticleOpen accessIn the author namesStudy of the Mandibular Glands of Ant Workers Atta sexdens rubropilosa (Forel, 1908) (Hymenoptera: Formicidae) Focusing the Ultrastructural CytochemistryLorena Favaro Pavon, Maria Izabel Camargo MathiasThe mandibular glands of hymenopterans in general are paired structures located on each side of the head. These glands possess an excretory duct located at the internal surface of the mandible articulation, through which these glands release the secretion they produce. The mandibular glands of the minima, media and soldier worker of the ant Atta sexdens rubropilosa were analyzed by … …American Journal of Agricultural and Biological Sciences, Vol. 1, Issue 2 · 30 Jun 2006 · 7,648 accessesView PDFCite
