    Which type of host(s) is not necessary for completing

    the life cycle of a pathogen but aids in its survival during unfavorable periods?
    A Collateral hosts Correct Answer Incorrect Answer
    B Alternate hosts Correct Answer Incorrect Answer
    C Wild hosts Correct Answer Incorrect Answer
    D Infected seed Correct Answer Incorrect Answer
    E Asymptomatic hosts Correct Answer Incorrect Answer

    Solution

    Collateral hosts are those that pathogens primarily attack but are not obligatory for completing their life cycles. They are part of the host range and aid in pathogen survival. In contrast, alternate hosts are crucial for completing the life cycle, while wild hosts and infected seeds serve as sources of primary inoculum.
