A review on biopesticidal activities of ethnobotanical plants

Abstract

Harmful organism that harms vegetables, fruits, crops, grains and all types of food stuffs stored in houses and ware houses is called pest. For the management of pest number of synthetic pesticides are used more frequently on vegetables crops and stored grain pests. However, due to its side effects on target specific organisms and non-target specific organisms a sustainable approach was performed to produce biopesticides of plant origin and are isolated from ethnobotanical plants for protection of crops, for increasing production of yields, for maintaining health of domestic animals and human beings and for their possible incorporation into the Management of pest/insect. In this review, bio-pesticidal activities of ethnobotanical plants were conducted by number of pioneer workers against number of pests by isolating its extract using soxhlation, cold percolation, vacuum evaporation, and by separating secondary metabolites of the extracts using thin layer and column chromatography. Obtained purified fractions of the ethnobotanical plant were applied on insect/pests for observing insecticidal / biopesticidal activities. From the results, it has been noticed that the extract and its fractions obtained from the ethnobotanical plants and their parts contain number of bioactive compounds including alkaloids, flavonoids, tannins, saponins, terpenoids that can be use as biopesticides and as an alternative source of synthetic pesticides/chemical pesticides. Biopesticides can be very cheap, easy and eco-friendly way of insect/pest management.
