    Question

    Which of the following is correct about NPVs (nucleopolyhedroviruses)?

    A.

    NPVs are host specific

    B.

    NPVs are photostable

    C.

    NPVs kill the host quickly

    D.

    None of the above

    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:
    1. 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.
