Part 8 (Chapter 9) Introduction to Urban and Industrial Integrated Pest Management

The Ambrosia beetles are so named because they feed only on [a].

Drywood termites have the ability to live in wood without contact with the [a] and are frequently carried in [b] objects into geographical areas where they are not normally found.

The term "powderpost beetle," used broadly, applies to any of the following three closely related families: Lyctidae, [a], and [b].

The [a] has a rusty red-brown to black color, covered with fine yellow hairs, giving it a velvety appearance.

Drywood termite infestations are frequently detected by the presence of the six-sided [a] which have been pushed out of the galleries.

Borates are toxic to [a] , but are not considered significantly hazardous to [b].

Termites other than [a] termites are divided into two groups: drywood and [b] termites.

The largest termites are found in the [a] termite group; they require wood with a high degree of [b].

Beetles belong to the Order Coloeptera, the largest of the insect orders. The [a] stage is responsible for almost all damage done to wood by beetles.

The first step in controlling wood decay is to locate and eliminate the source of [a]. This can usually be accomplished by mechanical alterations which provide for adequate circulation of [b].

The West Indian rough-headed powderpost drywood termite

a.)is of no commercial significance in the US

b.)has soldier heads that are plug-like

c.)is extremely destructive to woodwork

d.)has the scientific name Cryptotermes brevis

The Pacific dampwood termite

a.)is the largest of the native US termites

b.)is most commonly found in the warm and dry inland areas

c.)can survive for long periods in dry, sound wood

d.)is a significant pest at low altitudes

Residual insecticides (used against wood-boring beetles)

a.)that are oil-based give better control because of greater penetration into the wood

b.)should be water based formulations

c.)that are sprays should be applied at a low pressure using a flat fan nozzle

d.)may have oil carriers that have a solvent action on some wood finishes

Preventive measures to help reduce non-subterranean termite infestations include

a.)painting exterior wood

b.)inspecting lumber used in construction

c.)do not use moist or moisture-damaged wood

d.)screen all doors, windows, and ventilation openings

In heat fumigation,

a.)structures are tarped

b.)hot air is blown until a constant of 140 °F to 150 °F temperatures are reached

c.)temperature probes are not used

d.)it is more practical and economical for areas of manageable size

Wood damage in buildings caused by fungi

a.)can easily be controlled using fungicides

b.)especially rot fungi

c.)is best controlled by reducing moisture in and around structures

d.)usually start as a result of subterranean termite infestation

Moisture meters

a.)are not a useful component of a moisture control program

b.)can be used to monitor the success of moisture control programs

c.)are useful for determining the potential for wood decay

d.)can be used to determine the moisture level in wood

The old house borer

a.)feeds as a larva on living trees, recently felled logs, and seasoned lumber

b.)indoors is the only Cerambycid of major economic importance that can reinfest dry seasoned wood

c.)is a member of the Cerambycidae family

d.)has a very short life cycle

When inspecting for drywood termites

a.)wooden furnishings in the home need not be checked

b.)look for plugs in entrance and exit holes used by the termites

c.)the building perimeter should be checked carefully

d.)tap the wood to detect hollow galleries

Toxic mold

a.)can be harmful to humans through production of toxins and allergens

b.)is easily identified and controlled

c.)can trigger allergic reactions in sensitive individuals

d.)is a wood-destroying organism

1/8" exit holes in hardwoods only; frass is fine

1/16 - 1/8" exit holes; frass contains tiny bun-shaped pellets

¼ - 3/8" oval-shaped exit holes in softwoods only

Dark staining near small tunnels and holes in wood

Clean chambers and tunnels without fine frass; hard pellets packed in galleries

Provide five (5) guidelines for chemical management of wood-boring beetles.

List four (4) examples of procedures that can be used in a successful moisture control program.

The term "powderpost beetle" applies to three closely-related families of insects. List them.

Name a wood-boring insect (not termites) that can digest the cellulose that is found in wood.
