What is the primary ecological advantage of using baculoviruses of the genus Nucleopolyhedrovirus as biological control agents?

  1. Broad-spectrum insecticidal activity against all field insects
  2. Ability to genetically transform plant tissues to express systemic toxins
  3. Species-specific, narrow spectrum insecticidal applications with no negative impacts on non-target organisms
  4. Permanent persistence in soil ecosystems without requiring reapplication

Correct answer · Option 3

Species-specific, narrow spectrum insecticidal applications with no negative impacts on non-target organisms

Explanation

Baculoviruses in the genus Nucleopolyhedrovirus are excellent candidates for species-specific, narrow spectrum insecticidal applications with no negative impacts on plants, mammals, birds, fish, or non-target insects.
