Why they are a Pest
Both the adult and their larvae are problematic. The adults will eat leaves. The larvae cause the most damage as they live in the soil and eat the roots of plants. Many weevils are host specific and have names reflecting this eg. Mango seed weevil (Sternochetus mangiferae)
They can be found on curcurbits, parsley, tomatoes, eggplant, beetroot, carrot, potato, strawberry, cabbage, broccoli and lettuce.
Weevils are a serious pest in the agriculture industry feeding on grains such as wheat, barley, rye, oats and also grape vines. They will get into the stored grains and are common in foods made from grains like pasta.
