10. Subterranean wood destroying organisms 'trophallaxis' refers to:

11. Which termite species typically has the smallest colony size?

Clear selection

12. How do termites digest the cellulose found in wood?

Through symbiotic protozoa and bacteria in their gut.

They have multiple stomachs like cows and other ungulates.

By soaking the wood in their saliva to partially digest it before ingestion.

They don't; they only eat the fungus growing on the wood.

Clear selection

13. What happens if a subterranean termite worker is exposed to air with very low humidity?

It will grow wings and fly away.

It will start behaving erratically in a search for water.

It will die quickly due to desiccation (drying out).

It will call soldiers as part of it's defense response.

Clear selection

14. Which of these is a biological requirement for any termite colony to grow?

A source of cellulose and moisture.

Frequent exposure to sunlight.

A diet high in protein and fat.

Salt-rich soil.

Clear selection

15. Which termite species is known for creating 'carton' nests inside wall voids or attics?

Formosan subterranean termite

West Indian drywood termite

Powderpost beetle

Clear selection

16. What is the defining feature of 'frass' produced by drywood wood destroying organisms?

Liquid droplets left on the surface of walls.

Six-sided, seed-like pellets with longitudinal ridges.

Fine, powdery dust similar to flour.

Large chunks of chewed wood mixed with mud.

Clear selection

17. In Hawaii, the West Indian drywood termite is frequently found in which part of a home?

In the soil beneath the concrete slab.

Only in damp, rotting portions of the frame/structure.

Inside furniture, picture frames, and structural timbers.

Near plumbing pipes and drains.

Clear selection

18. When inspecting for subterranean wood destroying organisms, why is it important to check 'earth-to-wood' contacts?

Because termites prefer to eat soil rather than wood.

Because the wood stays drier when it touches the earth.

Because ants cannot climb on wood that touches the ground.

Because these points provide a direct, hidden entrance for termites from the soil into the structure.

Clear selection

19. Which of the following is a sign of an active infestation of drywood wood destroying organisms?

Mud tubes on the concrete foundation.

Accumulation of fresh, sand-like fecal pellets under 'kick-out' holes.

Leaking faucets and poor site drainage.

Painting the foundation white.
