The wheat weevil, also known as the grain weevil or granary weevil, is an insect that feeds on cereal grains, and is a common pest in many places. It can cause significant damage to harvested stored grains and may drastically decrease crop yields. The females lay many eggs and the larvae eat the inside of the grain kernels.
Hylobius abietis or the large pine weevil is a beetle belonging to family Curculionidae. This species is widely regarded as the most important pest of most commercially important coniferous trees in European plantations. Seedlings planted or arising from natural regeneration after clear felling operations are especially at risk. The adult weevils cause damage by eating the bark of seedlings around the 'collar' of the stem, thus 'ring-barking' the tree seedling which usually results in its demise.
