Excessive use of chemical products has caused some negative effects such as pesticide resistance, the emergence of new pests, side effects on natural enemies and environmental contamination. For these reasons, the search for alternative and environmentally ¿¿friendly¿ methods of pest control are encouraged. One such alternative is the use of the bioactive compounds, that are effective against target organisms and have shorter persistence in ecosystems. Plant extracts possess toxic compounds such as oviposition deterrents, repellents, antifeedants and also IGR effects on their target pests. Botanicals have plant secondary metabolites, thus offer an attractive and favorable alternative for pest management. There are lots of phytochemicals found in various native and toxic plants, but there are limited research works on the isolation, purification, and mode of actions. Even a single phytochemical at different concentrations expresses many physiological interruptions against the target pests Phytochemicals are safe to natural enemies, human being and environments. Hence, it is important to know the list of phytochemicals found in native plants that can be used in pest management.
