DESCRIPTION OF THE PESTS
Adults are 0.12 to 0.25 inch long, wedge-shaped, active insects that jump and
fly short distances when disturbed. Colors vary by species and are often
mottled or speckled with whitish green, yellow, and brownish gray. Adults
insert eggs into turfgrass leaves. Nymphs lack wings; their color varies with
species. Disturbed nymphs have a characteristic habit of moving sideways or
backwards. Generation time varies from 12 to 30 days, depending on species and
temperature.
SUSCEPTIBLE SPECIES
All grasses can be affected by leafhopper feeding.
DAMAGE
Although leafhopper sightings are not uncommon on golf courses and lawns,
severe injury usually occurs only with large leafhopper populations. Both
nymphs and adults suck sap from the leaves, resulting in yellowing or
bleaching. Affected turfgrass lose vigor and may die as a result of extended
presence of high populations.
MANAGEMENT
Generally treatment for leafhoppers is not needed. Treat only if populations
are high enough that damage is intolerable.
