Economic loss is not usually great except in some specific devastating conditions or when it involves the transmission of viruses.

Risk factors

Insect concerns are greater in warm production areas, in association with other susceptible crops (such as solanaceous hosts) in the vicinity or in the rotation, reduced soil preparation or limited use of insecticides.

Climatic changes, restricted use of insecticides and reduced soil ploughing are potential factors which can enhance the development or resurgence of insect damage.
