How can you tell the difference between wood suffering from brown rot
and wood suffering from white rot? - ANSWER ✔✔Wood infested
with brown rot typically:
• appears dark brown,
,• shows excessive shrinkage,
• develops cross-grain cracking, and
• can be crushed easily to form a brownish powder.
Wood infested with white rot on the other hand, often:
• appears whiter than normal,
• shows normal shrinkage,
,• does not crack across the grain,
• is spongy to the touch.
What is the difference between the stains caused by stain (sapstain)
fungi vs. mold fungi? - ANSWER ✔✔Sapstain fungi live on the starch
in wood cells. These fungi may discolor the sapwood entirely or in
patches. This stain is deep within the wood and cannot be removed by
brushing or planing.
On the other hand, discoloration caused by mold fungi is superficial. This
means that you can usually remove the discoloration by brushing or
planing. However, on hardwoods with open pores (very large and visible
vessels) such as the oaks, the surface molds may cause stains that are
too deep to remove easily.

, How can you distinguish between winged termites and winged ants? -
ANSWER ✔✔Look at their antennae, waists, and wings. Winged
termites have straight antennae, thick waists, and wings that are equal in
size and shape. Winged ants have bent antennae, narrow waists, and
forewings that are larger than the hind wings.
Name the four basic castes of termites. Describe the basic function(s) of
each caste. - ANSWER ✔✔Workers - gather food, maintain the
galleries, tend the young, and groom the other termites.
Soldiers - guard the colony against predators.
Primary reproductives - "swarmers" that fly out of their colonies to start
new colonies of their own. They are the future kinds and queens of new
colonies.
Secondary reproductives - supplement egg production in the presence
of the king and queen and can take over the egg laying if the queen dies
or begins to fail.
