    Warburgia Ugandensis and Croton Dichogamus: Possible Botanical Bullets against Callosobruchus Maculatus
    (A Multidisciplinary peer-reviewed Journal, 2025) Katoo, Athanas Alexander; Ngugi, Mathew; Gitahi, Stephen
    Botanical pesticides, derived from plant products, have gained significant popularity as an alternative to conventional synthetic insecticides. These natural products often consist of various bioactive compounds that offer effective pest control and may reduce the chances of pest resistance. However, challenges such as variation in pest response, short residual activity, and difficulties in large-scale production hinder their widespread use. This paper explores different generations of botanical pesticides, focusing on their chemical composition, modes of action, and applications. First generation botanical pesticides, including nicotine, rotenone, essential oils, sabadilla, and pyrethrum, are discussed, along with their associated limitations. The second-generation botanical pesticides, such as Melia extracts, synthetic pyrethroids, and neem products, are presented as more specific and environmentally friendly alternatives. Furthermore, the insecticidal potential of Croton dichogamus and Warburgia ugandensis, two East African plants, is examined. Both plants possess promising phytochemical properties that show potential for controlling pests like Callosobruchus maculatus in stored grains. This review highlights the ecological and economic value of these plants in pest management strategies and the sustainable use of plant-based pesticides.
