Biogenic amines are biological active compounds that play a significant role in regulation of animal physiology. In insects, the main amines are trace amines like octopamine and tyramine. Those two amines seem to be a partial counterparts of epinephrine and norepinephrine present in vertebrates. Little is known about activity of those compounds in beetles, hence we examined effects of 4 amines ...

The efficacy of phosphine has been established for numerous major stored product insects. However, data related to the evaluation effect on Tenebrio molitor L and Alphitobius diaperinus Panzer are limited. present study aims evaluate susceptibility these species by using following protocols: (a) all life stages were exposed 3 days different concentrations phosphine, (b) adults 3000 ppm until in...

Peptidoglycan recognition proteins (PGRPs) are a family of innate immune molecules that recognize bacterial peptidoglycan. PGRP-LE, a member of the PGRP family, selectively binds to diaminopimelic acid (DAP)-type peptidoglycan to activate both the immune deficiency (Imd) and proPhenoloxidase (proPO) pathways in insects. A PGRP-LE-dependent induction of autophagy to control Listeria monocytogene...

Inhabitants of the Indonesian island of Sumatra are faced with the problem of insufficient food supplies and the consequent risk of undernourishment and health issues. Edible insects as a traditional and readily available food source could be part of the solution. The nutritional value of insects depends on many factors, e.g., species, developmental stage, sex, diet, and climatic conditions. Ho...

Edible insects are a sustainable food source to help feed the growing population. Mealworms (Tenebrio molitor) can survive on variety of wastes and alter their composition based source. Commercial carrot production produces an abundance carotenoid-rich pomace, which may be beneficial for mealworm larvae growth. This study uses I-optimal response surface design assess effect dehydrated pomace co...

The 14-3-3 family of phosphorylated serine-binding proteins acts as signaling molecules in biological processes such as metabolism, division, differentiation, autophagy, and apoptosis. Herein, we report the requirement of 14-3-3ɛ isoform from Tenebrio molitor (Tm14-3-3ɛ) in the hemocyte antimicrobial activity. The Tm14-3-3ɛ transcript is 771 nucleotides in length and encodes a polypeptide of 25...
