Evaluar el consumo de poliestireno expandido (EPS) y polietileno baja densidad (PEBD) por larvas gorgojo negro (Tenebrio molitor), poder evidenciar en los diferentes tipos sustratos donde se desarrolla su estado larval. Los plásticos son difíciles degradar, principal contaminante Ríos, lagos océanos, pueden biodegradar mecanismos biológicos, especialmente insectos, coleópteros, que destacan mol...

An active fragment was identified from tenecin 1, an antibacterial protein belonging to the insect defensin family, by synthesizing the peptides corresponding to the three regions of tenecin 1. Only the fragment corresponding to the C-terminal beta-sheet domain showed activity against fungi as well as Gram-positive and Gram-negative bacteria, whereas tenecin 1, the native protein, showed activi...

Species of Fusarium have significant agro-economical and human health-related impact by infecting diverse crop plants and synthesizing diverse mycotoxins. Here, we investigated interactions of grain-feeding Tenebrio molitor larvae with four grain-colonizing Fusarium species on wheat kernels. Since numerous metabolites produced by Fusarium spp. are toxic to insects, we tested the hypothesis that...

Prolyl carboxypeptidase (PRCP) is a lysosomal proline specific serine peptidase that also plays a vital role in the regulation of physiological processes in mammals. In this report, we isolate and characterize the first PRCP in an insect. PRCP was purified from the anterior midgut of larvae of a stored product pest, Tenebrio molitor, using a three-step chromatography strategy, and it was determ...

The spectrum of Tenebrio molitor larval digestive proteinases was studied in the context of the spatial organization of protein digestion in the midgut. The pH of midgut contents increased from 5.2-5.6 to 7.8-8.2 from the anterior to the posterior. This pH gradient was reflected in the pH optima of the total proteolytic activity, 5.2 in the anterior and 9.0 in the posterior midgut. When measure...

One alternative to waste processing polystyrene is use Tenebrio molitor larvae. This study aims determine the increase in body length and weight, rate of degradation, value Waste Reduction Index (WRI) larvae T. molitor. used laboratory experimental using completely randomized design model (CRD) data analysis with control 4 feed treatments. Each treatment level was repeated 5 times order obtain ...
