It is gray to greenish yellow. Beet leafhoppers breed on weeds such as sowbane, lambs- quarters, and careless weed. Canta- loup plants are not their favorite food, and they do not reproduce on The beet leafhopper. They soon leave if there are no weeds in the field. If weeds are present, the leafhoppers will remain in the field and hop back and forth between the weeds and the cantaloup plants. The beet leafhopper

If weeds are present, the leafhoppers will remain in the field and hop back and forth between the weeds and the cantaloup plants. The beet leafhopper is the only in- sect known to transmit curly top, a virus disease that usually kills canta- loup plants in the seedling stage. Plants affected by curly top when they have 2, 3, or 4 leaves may be so stunted that they are worthless, or they may die. Plants affected after the 6-leaf stage may look undamaged; yet the quality and yield of the melons may be reduced. Older plants may show symptoms of curly top at the ends of the runners, such as shortening of the distance between leaves, and inward curling of leaves. Not all beet leafhoppers transmit the curly top virus. The percentage of virus carriers may be low or it may be high. Noncarriers can pick up the virus from plants infected by carriers and, in turn, infect healthy plants. A leafhopper infected with the curly top virus remains infective. The leafhoppers that you see in your fields may have come from different places. You cannot judge by their numbers alone how much damage they may do. The amount of damage de- pends on the number of virus carriers and the potency of the virus strain they carry. • Control.—Clean culture is a "must" in beet leafhopper control. Weed the fields as early as possible. Early weeding protects young plants, which are highly susceptible to curly top. By the time plants have begun to send out runners, they have developed considerable resistance to the disease. If beet leafhoppers migra
