Step-by-step solution

Dragonflies are useful to get rid of aphids and mosquitoes.

Bacillus thuringiensis (Bt) is a microbial biocontrol agent that can be introduced to control lepidopterans, dipterans, etc. The bacterial disease kills the caterpillars, but leave other insects unharmed.

Glomus is the genus that mainly forms the fungal part of mycorrhiza and helps in absorption of water and phosphorus.

Baculoviruses are pathogens that attack insects and other arthropods. These viruses have species-specific, narrow spectrum insecticidal applications.
