Deposition of black spots of fecal material on the plant by both nymphs and adults also detracts from the appearance and marketability of vegetables. This insect is rarely a pest of commercial vegetable crops because it is easily controlled with insecticides used against other, more serious, pests. However, it is commonly an early season nuisance in home gardens, especially those grown near wooded areas and on plants cultivated in semi-shade. This fleahopper has a broad host range, but leguminous crops are most frequently damaged. Vegetable crops that host garden fleahopper include bean, beet, cabbage, celery, cowpea, cucumber, eggplant, lettuce, pea, pepper, potato, pumpkin, squash, sweet potato, and tomato.
Field crops injured include alfalfa, clover, and sweet clover.
Occasionally it will feed on other insects. Natural Enemies Natural control has been poorly studied, but parasitic wasps can inflict high rates of mortality. L. uniformis attacks principally the nymphal stages. Beyer also reported several egg parasitoids, including Anaphes perdubius Girault and Anagrus sp. Management Suppression is easily accomplished with insecticides, including such botanical products as rotenone and sabadilla.
