Disease & Insect Management
|MOLECRICKET SYMPTOMS AND MANAGEMENT|
|LIFE CYCLE: Spend most
of their lives underground. When soil warms in the spring
and nighttime temperatures reach 60 F (15 C), tunneling
anf feeding increase. Eggs are laid in chambers 4-12
inches (10-30 cm) below the surface. Parents die off
after mating and egg-laying. Eggs take about 3 weeks to
develop nymphs, which tunnel to the surface and feed in
the upper soil and litter. Feed and burrow at night, just
below the soil surface.
FEEDING SYMPTOMS: Root feeder. Uproots the plants, causing roots to dry out.
control is best during mid-summer when crickets and
nymphs are small.
Chemical control: imidacloprid (MERIT) applied at the beginning of egg hatch, subsurface application of fipronil (CHIPCO CHOICE). Apply late in afternoon to dry turf. Broadcast: chlorpyrifos (DURSBAN), ethoprop (MOCAP), lambdacyhalothrin (SCIMITAR), bifenthrin (TALSTAR).
Biological control: parasitic waspLarra bicolor parasitic nematodesSteinernema and Heterorhabditis
