2007 article

The movement of proteins across the insect and tick digestive system

Jeffers, L. A., & Roe, R. M. (2007, December 4). Journal of Insect Physiology, Vol. 54, pp. 319–332.

By: L. Jeffers* & R. Roe n 

author keywords: digestive system; protein movement; protein insecticide
MeSH headings : Animals; Digestive System / metabolism; Insect Proteins / metabolism; Insecta / metabolism; Protein Transport; Ticks / metabolism
topics (OpenAlex): Insect Resistance and Genetics; Insect and Pesticide Research; Insect Pest Control Strategies
TL;DR: Protein movement was observed for both normal dietary and xenobiotic proteins, which suggest that the mechanism for transfer is not substrate specific and could be highly significant to the future of protein and nucleic acid-based insecticide development as well as traditional chemical insecticidal technologies.
