“…Also the ether extract fraction strong digestibility reduction in TM50 group in comparison to the control one can be ascribed to the increase of chitin level in daily feed intake. To explain that, two mechanisms can be assumed: 1) an amount of lipids are tied to insect cuticle where their function is to prevent desiccation (Klowden, 2013); 2) in general, lowering digestibility due to an increased chitin level in diet is responsible of an increased passage rate of feed through the digestive tract, lowering the apparent coefficient digestibility of all the nutrients.…”

“…The internal tracheal tubes are connected to the external environment through valve-like structures, known as spiracles, located along the exoskeleton. Oxygen-rich air is delivered directly to the cells, without requiring blood circulation, through thin-walled micron-scale tracheal tubes known as tracheoles [8]. Early investigations on the insect respiratory system suggested that for some insects gas exchange could be achieved solely by diffusion [9,21], but many insects supplement diffusion with convective transport [13].…”

“…The rhythmic and selective collapse behavior of tracheal tubes in RTC is made possible by the inherent structure of these tubes. Insect tracheal tubes are composed of two distinct layers: an outer layer of epithelial cells and an inner layer of chitin fibers embedded in a matrix known as the intima layer [11,8] (figure 2). The epithelial cells in the outer layer secrete mainly chitin and other proteins but likely do not play any mechanical role.…”

“…SISTEMA CIRCULATORIO Los insectos poseen un sistema circulatorio de tipo abierto, donde la hemolinfa baña los órganos de forma directa, facilitando el intercambio de nutrientes, desechos y hormonas, y participando además en la termo-regulación. La hemolinfa es impulsada por una bomba contráctil, el corazón, ubicada dorsalmente a lo largo de la línea media del abdomen, que se continúa con un conducto muscular denominado aorta que recorre el tórax y la cabeza (Hertel & Pass, 2002;Klowden, 2013).…”

“…Dependiendo del tipo de alimentación, de sus características y de cómo debe ser procesado el alimento, los sectores del tubo digestivo adquieren características especiales, tales como esclerotizaciones de la superficie interna del proventrículo, divertículos que se evaginan desde el esófago, secreciones proteicas especiales de las glándulas salivares, bolsas gástricas, etc. (Audsley & Weaver, 2009a;Klowden, 2013).…”
