Biological control techniques of Ectropis obliqua and Ectropis grisescens
Ectropis obliqua and Ectropis grisescens,which are related species of the same genus,are both main pests in tea plantations. In this paper,the research and application progress of the biological control of Ectropis oblique and Ectropis grisescens were summarized from the aspects of pest viral agents,sex pheromones,patnogenic bacteria and fungi,tea plant volatiles and utilization of natural enemies,and the biological control of the two pests was prospected,aiming at providing a reference for further research on the biological control of two species and solving the harm caused of the two pests in production.
