Question

Given below are two statements.
Statement I: Baculoviruses are pathogens that attack nematodes.
Statement II: Baculoviruses are used as biological control agents in ecologically sensitive areas as they are species-specific in their action.
In the light of the above statements, choose the correct answer from the options given below.

• A. Both Statement I and Statement II are true
• B. Both Statement I and Statement II are false
• C. Statement I is true, but Statement II is false
• D. Statement I is false, but Statement II is true

Hint:

Always remember: Baculoviruses target arthropods/insects only. They are the ideal candidates for species-specific, narrow-spectrum insecticidal applications in IPM.

Answer 1

The Correct Option is D

Step 1: Understanding the Problem:
Baculoviruses are important biological control agents used in integrated pest management (IPM) programs.
Step 2: Approach and Formula:
Verify the target organism profile and the ecological characteristics of Baculoviruses according to standard biological literature.
Step 3: Detailed Explanation:
- Statement I: Baculoviruses (mostly under the genus {Nucleopolyhedrovirus}) are pathogens that specifically attack insects and other arthropods, not nematodes. Fungi like {Pochonia} or specific bacteria are often used against nematodes. Therefore, Statement I is false.
- Statement II: Baculoviruses are excellent candidates for species-specific, narrow-spectrum insecticidal applications. They have no negative impacts on plants, mammals, birds, fish, or even non-target beneficial insects, making them ideal for use in ecologically sensitive areas. Therefore, Statement II is true.
Step 4: Final Answer:
Statement I is false, but Statement II is true.
