Eutettix Tenella when feeding, has the ability under certain conditions to produce a systemic disease, known as curly-top in the sugar beet. This ability is acquired by the insect after emerging from the egg as a result of feeding for only a short period upon a plant already diseased. After this feeding some time must elapse before the insect is able to transmit the virus to a healthy plant. This fact indicates that there may be a short incubation period for the virus in the insect. When once the ability to produce the disease is acquired there is no evidence to indicates that it is ever lost during the life of the insect. Although many insects of species other than Eutettix Tenella have been experimented with, not one has been found that is able to transmit the virus of curly-top.
