2014 journal article

Polymers for the stabilization and delivery of proteins topically and per os to the insect hemocoel through conjugation with aliphatic polyethylene glycol

PESTICIDE BIOCHEMISTRY AND PHYSIOLOGY, 115, 58–66.

By: L. Jeffers n, H. Shen n, B. Bissinger n, S. Khalil n, T. Gunnoe n & R. Roe n

author keywords: Insulin; Heliothis virescens; Tobacco budworm; PEGylation; Polyethylene glycol; Protein delivery
MeSH headings : Animals; Cattle; Drug Delivery Systems / methods; Hemolymph / metabolism; Insulin / chemistry; Insulin / metabolism; Larva / growth & development; Larva / metabolism; Moths / growth & development; Moths / metabolism; Polyethylene Glycols / chemistry; Polymers / chemistry; Polymers / metabolism; Protein Stability; Serum Albumin, Bovine / chemistry; Serum Albumin, Bovine / metabolism
TL;DR: Co-feeding of aliphatic polyethylene glycol (PEG), phospholipase A2, anionic and ionic detergents, and amphipathic glycoside with bovine serum albumin as a model protein to fourth stadium tobacco budworms, Heliothis virescens, did not affect the levels of BSA in the hemolymph.

2008 review

The movement of proteins across the insect and tick digestive system

[Review of ]. JOURNAL OF INSECT PHYSIOLOGY, 54(2), 319–332.

By: L. Jeffers* & R. Roe*

author keywords: digestive system; protein movement; protein insecticide
MeSH headings : Animals; Digestive System / metabolism; Insect Proteins / metabolism; Insecta / metabolism; Protein Transport; Ticks / metabolism
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.

INSECT BIOCHEMISTRY AND MOLECULAR BIOLOGY, 37(4), 363–374.

By: M. Deborah n, S. Khalil n, L. Jeffers n, D. Sonenshine*, R. Mitchell*, C. Osgood*, R. Roe n

author keywords: vitellogenin; vitellin; ticks; Acari; American dog tick; Dermacentor variabilis; heme
