Question

Why should we use bioinsecticides?

Answer 1

1. Chemical insecticides are poisonous and enter the food web. They have many adverse effects on humans and the environment.
2. On the other hand, bacterial and fungal toxins which can destroy pests and pathogens can be directly integrated into plants with the help of biotechnology.
3. Being toxic to insects, they do not consume the plants.
4. Similar to bacteria, some species of fungi and viruses are useful as pesticides. e.g. Spinosad, a by-product of fermentation is a biopesticide.
   Hence, in order to overcome the problems of chemical insecticides, we should use bioinsecticides.
