摘要： The noctuid species Spodoptera frugiperda (J. E. Smith), Spodoptera litura (Fabricius), and Mythimna separata (Walker) are among the most destructive agricultural pests globally. Currently, the management of these pests largely relies on chemical control methods, which are often inefficient, contribute to the development of insecticide resistance, and pose risks to environmental and food safety. In contrast, biological control using natural enemies, such as predators and parasitoids, has proven to be an effective, environmentally safe, and sustainable alternative. This approach has been successfully implemented in various regions of Africa, Asia, and the Americas. The assassin bug Rhynocoris fuscipes (Fabricius) is a key generalist predator that effectively controls a wide range of pests, including caterpillars, aphids, and planthoppers. However, its predation efficiency against the fall armyworm, common armyworm, and oriental armyworm remains poorly understood. In this study, we assessed the potential of R. fuscipes as a candidate biocontrol agent for managing these armyworm pests by examining its functional response, intraspecific interference competition, and prey preference. Our findings suggest that R. fuscipes shows strong potential as a biocontrol agent against these noctuid pests and provide valuable insights for optimizing its use in integrated pest management strategies.
