Abstract: The fall armyworm (Spodoptera frugiperda) is a major agricultural pest in the world. So far, it has spread to126 countries and regions around the world, causing serious damage to many major food and economic crops such as maize. Fall armyworm invaded China in January 2019 and quickly spread to 27 provinces. In 2021, the occurrence area of S. frugiperda has exceeded 1.38 millionha. Bacillus thuringiensis (Bt) is a gram-positive bacterium used to control agricultural pests. It has the characteristics of high efficiency and specificity for pests, environmental friendliness, and safety for humans and animals.Bt mainly relies on the insecticidal protein produced by it to exert its insecticidal effect. The sustainable control of fall armyworm mainly relies on genetically modified crops with Bt insecticidal genes and Bt microbial pesticides now. At present, a variety of high-efficiency Bt products such as Bt natural strains, genetically engineered Bt strains, and genetically modified (GM) crops have been developed in my country for the control of fall armyworm. This article will introduce the latest progress in the research of Bt control of fall armyworm domestic and abroad.

Key words: Spodoptera frugiperda, Bacillus thuringiensis, biological control, microbial pesticides, genetically modified crops
