摘要

Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) is a major invasive pest threatening tomato production globally. Its high adaptability, rapid reproduction, and global spread from South America to Europe, Asia, and Africa have made it a serious challenge for growers. Conventional management relies heavily on chemical insecticides such as pyrethroids and neonicotinoids. However, the development of resistance, environmental concerns, and impacts on non-target organisms have limited their long-term effectiveness. Alternative strategies are increasingly needed. Cultural and physical controls, such as crop sanitation and traps, offer partial success. Biological control using natural enemies has shown promise but faces implementation challenges. Among emerging approaches, plant essential oils (PEOs) have gained attention as natural, biodegradable insecticides. PEOs exhibit diverse bioactivities—neurotoxic, repellent, antifeedant, and ovicidal—making them effective against T. absoluta. This review explores the pest’s biology, current control methods, and the potential of PEOs as part of sustainable pest management strategies. Future research should focus on improving PEO formulation, stability, and field performance to enable wider adoption in tomato pest management programs, supporting Zero Hunger, Responsible Consumption and Production.
