- A They are broad-spectrum agents capable of killing nearly all insect pests
- B They are species-specific and do not harm non-target organisms
- C They remain heat-stable and persist for years within soil reservoirs
- D They produce potent chemical toxins that diffuse through plant tissue
Correct answer: B. They are species-specific and do not harm non-target organisms
Explanation: Baculoviruses (genus Nucleopolyhedrovirus) are species-specific and narrow-spectrum, affecting only the target insect pest without harming other organisms or the environment.
