HvarAKR1B1‐mediated tolerance in Hippodamia variegata: Deciphering the metabolic adaptation and fitness costs under prolonged starvation

Pest Management Science, EarlyView.
Starvation stress significantly affected the growth and development of Hippodamia variegata. Combined transcriptome and metabolome analysis and RNA interference verification revealed that HvarAKR1B1 may be involved in the response of Hippodamia variegata to starvation stress.

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.

CRISPR/Cas9-mediated Serine protease 2 disruption induces male sterility in Spodoptera litura

Frontiers in Physiology, 2022
Male fertility is essential for reproduction and population growth in animals. Many factors affect male fertility, such as courtship behavior, sperm quantity, and sperm motility, among others. Seminal Fluid Proteins (SFPs) are vital components of seminal

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

Pest Management Science, EarlyView.
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 Isoflavones by the Larvae of the Common Cutworm (Spodoptera litura)

Chemical and Pharmaceutical Bulletin, 2006
Biotransformation of the 5,7,4'-trimethoxyisoflavone (1), 6,7,4'-trimethoxyisoflavone (2), and 7,4'-dimethoxyisoflavone (3) by insects, Spodoptera litura was investigated. Compound 1 was transformed to 5-hydroxy-7,4'-dimethoxyisoflavone (4), 7-hydroxy-5,4'-dimethoxyisoflavone (5) and 4'-hydroxy-5,7-dimethoxyisoflavone (6) by S. litura.
