Abstract:
... The fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith), is one of the most highly polyphagous invasive pests causing serious damage to maize crops in China. However, little is known about the gut immune responses to the environment, particularly along the migration routes in Jianghuai, China, throughout the autumn and winter. In this study, high-throughput sequencing and real-time quantitativ ...

This study initially revealed that only α-CYP caused significant weight loss at 8.5 mg/(kg•day) in rats. All three CYP isomers caused the accumulation of hepatic glycogen, and hyperlipemia phenotype as the increment of total triglyceride. Rats treated w ...
