Biotechnology Plays a Significant Role to Control Insect Pests of Agricultural Crops

Today insect pests have been one of most important problem in food production. Previous research have been proved that 1/3 of agricultural production of world, prized at several billion dollars is ruined by damaging of field and storage insect pests every year. Various toxic, broad-spectrum and synthetic chemicals are used to control pests. Natural ecosystem, human health and our environment can be affected due to excessive use of these harmful chemicals. So now biologically based approaches are developing to control insect pest instead of toxic and synthetic chemicals which are ecofriendly, cost-effective and useful and reliable. There are different types of bio pesticides such as arthropods natural enemies (predators, parasitoids, and parasites), entomopathogens (bacteria, fungi, virus and nematodes), insect hormones and plant derived bio pesticides.
