“…5 in Sales et al, 2001). More recent findings have demonstrated that vicilin molecules are absorbed by the midgut epithelium of C. maculatus larvae (Uchôa et al, 2006;Souza et al, 2010). In the light of these new discoveries concerning the fate of ingested vicilins in C. maculatus larvae, we decided to reinvestigate the localization of variant vicilins in the midgut of larval cowpea beetle, taking into consideration the possibility of an intracellular target for the absorbed variant vicilins.…”

“…Uchôa et al (2006) demonstrated that vicilins were absorbed intact through the midgut of C. maculatus larvae, and where subsequently detected in the haemolymph and internal organs such as fat body and malphigian tubules. The absorbed vicilin molecules were detected in adult females and males after emergence and were also deposited in the eggs following copulation (Souza et al, 2010;Alexandre et al, 2011).…”

“…This was suggested a long time ago, and the idea of manipulating the titre and metabolism of peptides with endocrine functions appeared particularly amenable to develop new insect control technologies, even though quite a few concerns were raised about the effective occurrence of peptide gut absorption (Schneidermann, 1984;Keeley and Hayes, 1987;Menn and Borkovec, 1989). However, the peptide/protein degradation in the gut upon ingestion is not an absolute barrier, and a consistent experimental evidence indicates that absorption of molecules and macromolecules takes place at detectable levels (Bavoso et al, 1995;Kurahashi et al, 2005;Casartelli et al, 2005;Uchoa et al, 2006;Fiandra et al, 2009). As the background information in these basic field of study continues to grow, the possibility of integrating different tools and approaches to develop new biotechnologies for insect control appears to be particularly promising, and certainly worthy of further research efforts.…”

“…Among these, secondary metabolites such as terpenic metabolites, phenols, alkaloids and cyanogenic glycosides. Similarly the proteins are also involved in the defensive capabilities of many green plants have been reported [30]. Such as proteins include digestive enzyme inhibitors, chitinases, vicilins, lectins and lectin-like proteins, these proteins have potential use as naturally occurring insecticide agents against pests and insect control [31].…”
