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.
