Abstract:

A long period of evolution causes obviously diurnal and seasonal rhythmic changes in insect life and behavior-circadian clock. At present, Lepidoptera is the most species-rich group of insects, including about 160000 identified species of butterflies and moths, and nearly 70% of the important major agricultural and forestry pests belong to Lepidoptera. The research progress of the circadian clock in Lepidoptera is of great significance for in-depth analysis of variable physiological and behavioral regulation mechanisms of Lepidoptera, effective development of the production of economic insects, and the control of agricultural and forestry pests. In this paper, the effects of the circadian clock on hatching, eating, growth, metamorphosis, reproduction and diapause, courtship behavior and migration in Lepidoptera were summarized. And the critical research advances of molecular regulation of circadian clock and coordinated regulation of circadian clock and endocrine hormones in Lepidoptera were particularly described. Based on the circadian clock principle, we discussed the co-evolutionary relationship between Lepidoptera and plants and its important ecological implications, and the application prospect of circadian clock theory in agricultural pest control and economic insect rearing improvement.
