Baculoviruses are good example of bio-control agents. Justify giving three reasons.

Explanation

**Step-by-Step Solution:**

1. **Definition of Baculoviruses**: Baculoviruses are a group of viruses that specifically infect insects and other arthropods. They are known for their pathogenic properties, making them effective in controlling pest populations.

2. **Reason 1 - Pathogenicity**: Baculoviruses are pathogens that primarily target insects. This specificity allows them to effectively reduce pest populations without harming beneficial insects. They infect the host insect, leading to its death, which helps in managing pest outbreaks.

3. **Reason 2 - Narrow Spectrum**: Baculoviruses are excellent candidates for narrow-spectrum insecticidal applications. This means they can selectively target specific pest species without affecting non-target organisms. This selectivity is crucial in integrated pest management strategies, as it minimizes the impact on beneficial insects and the ecosystem.
