Gorgojo, Black Vine Weevil

Description:

The adult weevil is matte black with fused wing covers, and is unable to fly. It feeds at night on the outer edges of leaves, causing the leaves to have a notched margin. Broadleaved evergreen plants such as Camellia, Rhododendron, Euonymus and Bergenia are particularly prone to damage, although a wide range of different garden plants is susceptible to attack

Habitat:

Sub-tropical mountain forest in central Guatemala at 1800 msn They live below the soil surface, and feed on roots and cambium at the base of the trunk. They cause most damage to herbaceous plants, particularly those growing in containers, where root growth is restricted. Severe infestations can result in complete root destruction and hence plant death.

Notes:

Son una importante plaga de los cultivos tanto las larvas como los adultos. Las larvas se alimentan de las raíces de las plantas. Los adultos poseen los élitros fusionados y no vuelan y se alimentan durante la noche de las hojas de las plantas. Se reproducen asexualmente (partenogegéticamente).
