The insect midgut epithelium represents an interface between the internal and the external
environment and it is the almost unique epithelial tissue by which these arthropods acquire …

Simple Summary The Malpighian Tubules (MTs) are well known and studied as the main
excretory organs in most insects. However, MTs, despite their quite simple morphology, can …

New approaches have led to advances in the molecular knowledge of digestion and nutrient
absorption in insects. Cell fractionation with proteomics revealed the molecular composition …

The spatial organization of digestion, which corresponds to the steps by which the ingested
food is hydrolyzed in the different regions of the gut, was described in insects from the major …

The spectacular radiation of insects has produced a stunning diversity of phenotypes.
During the past 250 years, research on insect systematics has generated hundreds of terms …

Because food proteins are crucial for insect survival, growth, and fecundity, enzymes
involved in their digestion have attracted the attention of fundamental entomologists …

Background While apocrine secretion was among the earliest secretory mechanisms to be
identified, its underlying basis remains poorly understood. Scope of review This review …

Chymotrypsins (CTP) are a main type of proteolytic digestive enzymes in Lepidopteran
insects. They can play a major role in degrading activated Bt toxin in some insect species …

Cockroaches are among the first insects to appear in the fossil record. This work is part of
ongoing research on insects at critical points in the evolutionary tree to disclose evolutionary …

Background Stick and leaf insects (Phasmatodea) are an exclusively leaf-feeding order of
insects with no record of omnivory, unlike other “herbivorous” Polyneoptera. They represent …
