Curly top virus of sugar beet, named for the severe curling and distortion it causes to the leaves of infected plants, is transmitted through the feeding activities of the beet leaf hopper (Circulifer tenellus, Baker). Because the virus can be transmitted in only a few minutes of feeding, control of the leafhopper could theoretically be achieved only by insecticides which kill faster than it takes the insect to complete a transmission feeding.
