Correct option is A
The correct answer is: (A) NPVs are host specific
Explanation:
Nucleopoly hedro viruses (NPVs) are a type of baculovirus that infects specific insect species, mainly lepidopteran pests (caterpillars and moth larvae).
These viruses are highly host-specific, meaning they do not affect non-target organisms like humans, plants, or beneficial insects.
Information Booster:
Host Specificity of NPVs:
NPVs infect only specific insect species and do not harm beneficial insects, making them ideal for biological pest control.
Example: Autographa californica NPV (AcNPV) infects the alfalfa looper caterpillar.
