Give the name of pathogen which attack on insect and other Arthopods so used as biological control agents.

Answer

**Step-by-Step Solution:**

1. **Understanding Biological Control Agents**: Biological control involves using natural organisms to manage pest populations. This method is part of Integrated Pest Management (IPM), which aims to maintain ecosystem stability and biodiversity while controlling pest populations.

2. **Identifying Pathogens**: Pathogens that attack insects and arthropods can be utilized as biological control agents. These include bacteria, fungi, and viruses.

3. **Recognizing Specific Pathogens**:
- **Bacillus thuringiensis (Bt)**: A bacterium that is effective against caterpillars.
- **Trichoderma**: A fungus used for various pest control applications.
- **Baculoviruses**: A group of viruses specifically targeting insects and arthropods.

4. **Focusing on Baculoviruses**: The question specifically asks for a pathogen that attacks insects and arthropods. Baculoviruses are known for their effectiveness in controlling pest populations.

5. **Genus Identification**: Baculoviruses belong to the genus **Nucleopolyhedrovirus**, which is significant in biological pest control.

6. **Final Answer**: The pathogen that attacks insects and other arthropods, used as a biological control agent, is **Baculovirus**.
