Question
Why should we use bioinsecticides?
Solution
- Chemical insecticides are poisonous and enter the food web. They have many adverse effects on humans and the environment.
- 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.
- Being toxic to insects, they do not consume the plants.
- 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.
