Technique B because it preserves the harmless insects and targets only the moth larvae
Explanation:
The technique with the least impact on the environment is technique B because it preserves the harmless insects and targets only the moth larvae.
The environment is made up of living and non-living components. Together, the components interacts to define the ecosystem.
- A control method for pest that is best desired is one that selectively targets the unwanted organism.
- Technique B is engineered towards destroying the harmful larvae.
- This achieves the result with little impact on the balance on the ecosystem.
- Unlike technique A, it does not destroy other insects which can be very useful in plant pollination.

Just think of it like this: Fungi is basically like garbage collectors. They will recycle the stuff that you dont need and or want.
