Many domestic and international scholars have done a wide range of researches on electromagnetictheory and technology and have made some achievements. Electromagnetic technology has been used inforest pests control as a convenient and high-efficient physics means. This article summarizes the currentstudy of the electromagnetic biological effect and introduces the application of microwave, pulsedelectromagnetic field and electrostatic field to forest pests control. The research direction and prospect of theapplication of electromagnetic theory and technology to forest pests control are also discussed.
