    Question: Mining and skeletonization of cabbage leaves is caused by?

    Options:

    Diamond back moth
    Leaf webber
    Head borer
    Semilooper

    ✅Explanation:The diamond back moth, also known as the cabbage moth, is the primary culprit behind mining and skeletonization of cabbage leaves.
    -Mining: Diamondback moth larvae are small and green, initially feeding by mining within the leaf tissue.
    -Skeletonization: As the larvae mature, they start feeding on the outer layers of the leaf, leaving only the veins intact. This gives the leaf a skeletonized appearance.

    📌 Other options Explanation:
    -Leaf webber: While some leaf webber species might cause feeding damage to cabbage leaves, they typically spin silken webs around the leaves for protection.
    -Head borer: This pest mainly targets the cabbage head itself, burrowing and feeding inside the developing heart of the cabbage.
    -Semilooper: Though some semilooper caterpillars can feed on cabbage leaves, their feeding pattern typically involves consuming large chunks of the leaf tissue.
