Bioactivity of plant extracts against cowpea bruchid Callosobruchus maculatus (Fab): a review

The objective of the present review is to know the bioactive compounds of the plant extract against Callosobruchus maculatus. Plants are able to produce a large number of bioactive compounds. Plant extract was found to have a wide range of bioactive compounds like Alkaloids, Carbohydrates, Starch, Glycosides, Flavonoids, Triterpenoids, Resins, Saponins, Steroid, Proteins and Tannins. The high concentration of phytochemicals protects against the Callosobruchus maculatus. Recent revelations have shown that synthetic insecticides were found to penetrate into grains and may be toxic. Natural products such as botanical insecticides may provide suitable alternatives. The review obviously designated that plant products have potentials of controlling Callosobruchus maculatus in stored cowpea as they are safe, free of residue and strong biological activities that are eco-friendly and biodegradable.
