Estudos anatômicos e histológicos sôbre a subfamília Triatominae (Heteroptera, Reduviidae): IV. parte: o complexo das glândulas salivares de Triatoma infestans

Abstract: Foram descritas anatômica e histològicamente as glândulas labiais modificadas que são um par de complexos glandulares, cada um composto de três glândulas. Cada glândula tem uma parede formada por uma camada unicelular limitando uma cavidade relativamente grande, o reservatório. As duas primeiras glândulas (D 1 e D 2) encontram-se justapostas uma à outra. Entre elas é formado um hilo que tem um canal auxiliar que o liga à terceira glãndula ( D 3), situada mais para trás. Pelo hilo as três secreções das glândula… Show more

“…Previous physiological studies of the salivary gland from Triatoma infestans described that cells entered an inactive state at 10-14 days after feeding. Five minutes after feeding, salivary gland cells were highly active, as characterised by an increased size, resumption of secretion and protoplasmatic regeneration (Barth 1954). These findings are in agreement with our results, in which more cells were adherent to plates in Araujo et al (2006).…”

“…In triatomines, the main salivary glands are composed of a single layer of epithelial cells that surrounds the large central lumen and a thin basal lamina containing tracheolae, muscle fibres/myofibrils (Barth 1954, Lacombe 1999, Reis et al 2003 and neuronal terminations . The morphology of the cells is still not completely known.…”

“…They showed a predominance of two bulky and polyploid nuclei in each cell, as observed in salivary gland of Triatoma infestans (Klug, 1834) and Panstrongylus megistus (Burmeister, 1835) (anHê & azereDo-oliVeira, 2008). According to BartH (1954), this increasing of nuclear mass may provide the intense metabolism, essential to accelerate and regulate cellular regeneration after saliva secretion. Polyploidy is a common phenomenon in many insect tissues, as midgut, epidermis, fat body, Malpighian tubules, trachea and ovary follicle (eDgar & orr-weaVer, 2001 (Martínez et al, 2014).…”

“…According to BartH (1954), there are four to six phases, including transport of substances, secretion of the saliva and cell regeneration. BartH (1954) and laCoMBe (1999) also observed that the insect nutrition changes the cell morphology. To avoid this variable, in this study the insects were dissected seven days after feeding.…”
