RNA Interference of Chitinase Gene in Spodoptera litura [PDF]

The Korean Journal of Pesticide Science, 2014
RNA interference (RNAi) is the method which controls phenotypes of gene in live cells. Chitinase is the enzyme helping digestion and absorption of old cuticles during the ecdysis of insects. In order to investigate molting-inhibition effect with the chitinase related gene in Spodoptera litura, RNA was extracted from the instars.

Bt agave: why it is time to explore a new biotechnological frontier

Pest Management Science, Volume 82, Issue 9, Page 8053-8063, September 2026.
Drylands cover 41% of Earth, requiring sustainable crops. Agave, drought‐ and heat‐adapted, offers high‐value products with low water needs. Pests limit yield, yet Bacillus thuringiensis (Bt) Cry proteins, successful in other plants, remain unexploited in Agave.

Biotransformation of Sinesetin by the Larvae of the Common Cutworm (Spodoptera litura)

Biological and Pharmaceutical Bulletin, 2004
Biotransformation of sinesetin (1) by larvae of Spodoptera litura was investigated. Compound 1 was converted to a new flavonoid, (+)-5,7,3',4'-tetramethoxyflavone-6-O-beta-D-glucoside (4), and two known flavones, 4'-hydroxy-5,6,7,3'-tetramethoxyflavone (2) and 6-hydroxy-5,7,3',4'-tetramethoxyflavone (3).

Valorization of Ficus carica Pruning Residues as Selective Botanical Insecticides: Optimized Furanocoumarin Extraction, Efficacy Against Neotropical Stink Bugs, and Mechanistic Insights via Molecular Docking

Archives of Insect Biochemistry and Physiology, Volume 122, Issue 4, August 2026.
Optimized extracts from Ficus carica pruning waste exhibit strong biological activity against major stink bug pests. Complementary in silico analyses suggest this efficacy relies on pest‐specific acetylcholinesterase inhibition, predicting a promising, pollinator‐safe alternative for sustainable agriculture.
