Abstract: Purpose: To aim of the study was to analyze the role of plant secondary metabolites in insect herbivore resistance in Kenya. Methodology: This study adopted a desk methodology. A desk study research design is commonly known as secondary data collection. This is basically collecting data from existing resources preferably because of its low cost advantage as compared to a field research. Our current study looked into already published studies and reports as the data was easily accessed through online journals and libraries. Findings: Plant secondary metabolites in Kenya play a vital role in defending against insect herbivores. These compounds, such as alkaloids, terpenoids, and phenolics found in crops like maize, beans, and tomatoes, act as chemical deterrents and toxins, altering herbivore feeding behavior and physiology. This defense mechanism is crucial for sustainable pest management in agriculture, offering natural alternatives to synthetic pesticides and promoting ecological balance. Ongoing research explores optimizing these compounds for effective pest control strategies across diverse environmental conditions in Kenya. Unique Contribution to Theory, Practice and Policy: Optimal defense theory (ODT), induced defense theory (IDT) & resource availability hypothesis may be used to anchor future studies on role of plant secondary metabolites in insect herbivore resistance in Kenya. In agricultural and horticultural practices, leveraging knowledge of plant secondary metabolites can enhance pest management strategies. From a policy perspective, recognizing the ecological benefits of plant secondary metabolites can inform agricultural policies aimed at promoting sustainable practices and reducing chemical inputs.
