The fall armyworm, Spodopterafrugiperda, is a lepidopteran pest that feeds on many economically important cereal crops such as corn, rice, sorghum, and sugarcane. Native to the Americas, it has become a serious invasive pest in Africa and Asia. Recently, this pest was found in China and has spread quickly across the country. As S.frugiperda will most likely become a major pest in China, Integrated Pest Management strategies, including biological control methods, should be developed to manage its populations. Here, we report the detection of Telenomusremus parasitizing S.frugiperda eggs in cornfields in southern China based on morphological and molecular evidence. Our preliminary surveys indicated that the parasitism rates of T.remus on S.frugiperda could reach 30% and 50% for egg masses and per egg mass, respectively. Further application of T.remus against S.frugiperda in biological control programs are discussed.
