Circadian regulation of night feeding and daytime detoxification in a formidable Asian pest Spodoptera litura

Abstract

Zhang et al. show that the circadian gene coupling between night feeding and day detoxification is regulated through the binding of circadian elements to E-boxes in Spodoptera litura, one of the most difficult Asian agricultural pests to control. Exposure of these larvae to a pesticide affects them more at night than during the day, suggesting the need for time-of-day considerations for pesticide application.
