What is a common characteristic of damage caused by Alfalfa Weevil larvae?

The damage caused by Alfalfa Weevil larvae is primarily characterized by skeletonizing or shredding of new growth tips. Alfalfa Weevil larvae feed on the tender, succulent parts of the alfalfa plants, specifically targeting the upper shoots and leaves. This feeding behavior results in a distinctive pattern where the leaf tissue is consumed, leaving only the veins intact. As a consequence, the new growth tips can appear ragged or shredded, and the overall health of the plant can be significantly compromised. This feeding can stunt growth and reduce the quality of the forage produced, making it a key concern for agricultural management in alfalfa crops.

While complete defoliation is a serious form of damage, it is not typical for the feeding patterns of Alfalfa Weevil larvae, who often leave some foliage intact. Root rot primarily relates to soil and moisture conditions and is not a direct result of larval feeding. Wilting of plants can occur due to various stress factors, but it does not specifically indicate the unique feeding activity of Alfalfa Weevil larvae. Therefore, skeletonizing or shredding of the new growth tips accurately reflects the specific damage caused by these pests.
