Biopesticides: Uses and importance in insect pest control: A review

Biopesticides are made up of plant materials that kill insects and a variety of microorganisms that kill insects, such as entomopathogenic fungi, entomopathogenic bacteria, entomopathogenic viruses, and entomopathogenic nematodes. These are used to get rid of agricultural and household insect pests. Several new methods are being developed in the biopesticide sector, and production and marketing of biopesticides are increasing significantly worldwide because of the noteworthy results in integrated pest management. Lots of Bt-genic crops, different types of entomopathogenic bacteria, entomopathogenic viruses, entomopathogenic fungi, and nematode-associated entomopathogenic bacteria are available in the market and are being used in agriculture to protect crops from insect pests and reduce insect pest populations. In the present review, we describe the role of biopesticides, including microbial and plant-derived ones, in insect pest management and the importance of their uses. An updated illustration of the present information on biopesticides and the availability of their commercial products and active substances in plants that can be very helpful in Insect pest management is reported in this review.
