What does it mean when a grass goes dormant? - Correct Answer-The
grass has died off (turned brown) because of too cold or too hot of
conditions and will green up when when the conditions are right again
What is Thatch? - Correct Answer-A layer of living and dead plant stems,
leaves, and roots that develop between the soil surface and green
vegetation
What is Dethatching? - Correct Answer-The process of reducing or
removing thatch
What is Aeration? - Correct Answer-Practice that removes plugs from the
soil and lets in air flow and nutrients
Which method will NOT help monitor cutworms? - Correct Answer-Pitfall
traps

What is Bacillus thuringiensis (Bt) ? - Correct Answer-A common bacterium
that kills many types of caterpillars
When should you apply an insecticide? - Correct Answer-When the insect
is at its most vulnerable stage
What is the Milky spore disease? - Correct Answer-A bacterial disease that
is caused by the bacterium, Bacillus popilliae, and kills Japanese beetles
What do you do to control fire ants? - Correct Answer-Use a combination of
broadcast bait and mound treatments
Sod webworms... - Correct Answer-Spin silk webbing near the soil in turf
An insecticide applied to control white grubs... - Correct Answer-Should be
watered in to reach the soil
Mole crickets... - Correct Answer-Have only one generation per year

What are the 2 different kinds of metamorphosis that insect pests undergo?
- Correct Answer-1.) Gradual metamorphosis: Nymphs (young stages) of
insects that undergo this look like small versions of the adult
2.) Complete metamorphosis (most common type of development among
turf grass pests): The young stages of insects that undergo this look very
different from the adults before before they become pupae and change into
adults
How do Chinch bugs damage turf? - Correct Answer-They feed in clusters
and damage first appears as circular patches of yellowing turf that
resemble drought injury and large infestations of the southern chinch bug
may completely kill St. Augustine lawns.
What are 4 pests that might cause root damage to turf? - Correct Answer-
1.) Japanese beetle
2.) Mole cricket
3.) Masked chafer
4.) Green june beetle
How does frequent mowing impact fire ants? - Correct Answer-Frequent
mowing is a control method that golf course managers use to force red
imported fire ant colonies to less disturbed areas. The more times areas
are mowed, the less time fire ants have to establish colonies
What are 3 ways to find turf insects in the soil? - Correct Answer-1.)
Scouting
, Page |4
2.) Sampling
3.) Monitoring
There are 3 different kinds of traps that are used to monitor insects. What is
the role of each trap in monitoring turf insects? - Correct Answer-1.) Light
traps: Uses an ultraviolet (UV) bulb that attracts most night flying insects to
trap insects so you can count the number of adult insects that will produce
turf-damaging caterpillars, grubs, or cutworms and predict when turf
damage could occur
2.) Pheromone traps: Traps that are developed for the Japanese beetle
adult, cutworm moth, and the larger sod webworm moth to let you monitor
a single species
3.) Pitfall traps: Traps that are developed to catch and monitor Billbugs by
using a 16-ounce cup buried up to the rim in, or next to the turf. Billbug
adults fall into the trap and can be counted to monitor the beginning of
activity in the spring (petroleum jelly applied in a band near the top of the
cup will prevent bill bugs from crawling out
What are 4 pest-control problems that are caused by a thick layer of
thatch? - Correct Answer-1.) It reduces winter shelter for many pests
2.) Thick thatch creates a more uniform humidity zone for sod webworms,
cutworms, and chinch bugs. Thinner thatch allows the soil surface to dry
out
3.) Billbug larvae and (sometimes) white grubs feed on thatch
4.) Thatch hinders the movement of biological controls or pesticides.
Thatch may bind a pesticide so tightly that it does not get through the soil to
come into contact with the target pest
