FLORIDA TERMITE & WDO EXAM PRACTICE QUESTIONS
200 Multiple Choice Questions with Rationales
SECTION 1: TERMITE BIOLOGY & IDENTIFICATION (Questions 1-40)
1. Which of the following termite species is the most economically
significant wood-destroying pest in Florida? A) Drywood termite B) Formosan
subterranean termite C) Eastern subterranean termite D) Dampwood termite
Answer: B) Formosan subterranean termite (correct answer) Rationale:
While all listed species occur in Florida, the Formosan subterranean termite
(Coptotermes formosanus) is considered the most destructive due to its massive
colony sizes (up to several million individuals), aggressive foraging behavior, and
ability to cause rapid structural damage. It is also an invasive species in Florida.
2. What is the primary difference between subterranean and drywood
termite swarmers (alates) regarding their wings? A) Subterranean alates
have two pairs of equal-length wings; drywood alates have forewings longer than
hindwings B) Subterranean alates have forewings and hindwings of equal length;
drywood alates have forewings longer than hindwings C) Subterranean alates
have no wings; drywood alates have two pairs D) Both have identical wing
structures Answer: B) Subterranean alates have forewings and hindwings of
equal length; drywood alates have forewings longer than hindwings
(correct answer) Rationale: Subterranean termite alates have two pairs of
membranous wings that are nearly equal in length. Drywood termite alates have
forewings that are distinctly longer than their hindwings. This is a key diagnostic
feature for identification.
3. Which caste of subterranean termites is responsible for consuming
wood and causing structural damage? A) King and Queen B) Soldiers C)
Workers D) Alates Answer: C) Workers (correct answer) Rationale: Worker
termites are the only caste with mouthparts capable of digesting cellulose. They
feed the entire colony, including soldiers, reproductives, and nymphs. Soldiers
,cannot feed themselves due to their large mandibles, and reproductives/alates
do not consume wood.
4. The “swarming” behavior of termites typically occurs during which time
of day in Florida? A) Early morning after rainfall B) Midday in dry conditions C)
Late evening or night D) Only during winter months Answer: A) Early morning
after rainfall (correct answer) Rationale: Subterranean termite swarms in
Florida typically occur on warm, humid days, often following rainfall, during late
morning to early afternoon. Drywood termites tend to swarm in late evening or at
night. The question specifies typical Florida conditions where subterranean
swarms are most common.
5. What is the primary function of soldier termites in a colony? A) To
reproduce and lay eggs B) To forage for food C) To defend the colony against
predators D) To construct mud tubes Answer: C) To defend the colony against
predators (correct answer) Rationale: Soldier termites have enlarged
mandibles or fontanelles (glandular openings) that secrete defensive
compounds. Their sole purpose is colony defense against ants and other
predators. They cannot feed themselves and must be fed by workers.
6. Which physical characteristic distinguishes Formosan subterranean
termite soldiers from native subterranean termite soldiers? A) Formosan
soldiers have a teardrop-shaped head; native soldiers have rectangular heads B)
Formosan soldiers have an oval-shaped fontanelle on the head; native soldiers
have a fontanelle on the pronotum C) Formosan soldiers have a teardrop-shaped
head with an oval fontanelle; native soldiers have rectangular heads with a
fontanelle on the pronotum D) There is no visible difference Answer: C)
Formosan soldiers have a teardrop-shaped head with an oval fontanelle;
native soldiers have rectangular heads with a fontanelle on the pronotum
(correct answer) Rationale: Formosan subterranean termite soldiers have an
oval-shaped fontanelle (pore) on the front of their teardrop-shaped head, from
which they emit a white defensive secretion. Native subterranean termite soldiers
(Reticulitermes) have a rectangular head with a fontanelle located on the
pronotum (plate behind the head).
,7. What is the typical lifespan of a subterranean termite queen? A) 1-2 years
B) 5-10 years C) 15-25 years or more D) Only during the swarming season
Answer: C) 15-25 years or more (correct answer) Rationale: Subterranean
termite queens are among the longest-living insects. They can live 15-25 years
or longer under optimal conditions, continuously laying thousands of eggs per
day throughout their lives. This longevity contributes to colony persistence.
8. Drywood termite fecal pellets (frass) are typically characterized by: A)
Soft, moist, and clumped together B) Hard, elongated, hexagonal-shaped, and
found in kick-out holes C) Liquid and sticky D) Powdery and white Answer: B)
Hard, elongated, hexagonal-shaped, and found in kick-out holes (correct
answer) Rationale: Drywood termites push their hexagonal, ridged fecal pellets
out of small “kick-out holes” in wood. These pellets are hard, dry, and have
distinct six-sided shapes. This is a primary sign of drywood termite infestation
and differs from subterranean termite frass, which is not typically visible since
they use mud tubes.
9. Which of the following is NOT a characteristic of dampwood termites? A)
They require wood with high moisture content B) They do not require soil contact
C) They are commonly found in structural lumber in Florida homes D) They are
larger than subterranean termites Answer: C) They are commonly found in
structural lumber in Florida homes (correct answer) Rationale: Dampwood
termites (Neotermes spp.) require very high wood moisture content and are
rarely found in sound, dry structural lumber. They typically infest decaying wood,
tree stumps, and logs. In Florida, they are more common in natural settings than
in structures, unlike subterranean or drywood termites.
10. The process by which termites break down cellulose into digestible
nutrients involves: A) Enzymes produced solely by the termite’s own digestive
system B) Symbiotic protozoa and bacteria in the hindgut C) Chewing wood into
extremely fine particles D) External digestion before ingestion Answer: B)
Symbiotic protozoa and bacteria in the hindgut (correct answer) Rationale:
Termites harbor symbiotic microorganisms (flagellate protozoa in lower termites,
bacteria in higher termites) in their hindgut that produce cellulase enzymes.
, These microorganisms break down cellulose into simple sugars that the termite
can absorb. Without these symbionts, termites cannot digest wood.
11. What is the primary difference between primary and secondary
reproductives in a termite colony? A) Primary reproductives have wings;
secondary reproductives are wingless B) Primary reproductives are larger;
secondary reproductives are smaller C) Primary reproductives founded the
colony; secondary reproductives develop within the colony to supplement egg
production D) Primary reproductives produce only workers; secondary
reproductives produce only soldiers Answer: C) Primary reproductives
founded the colony; secondary reproductives develop within the colony to
supplement egg production (correct answer) Rationale: Primary
reproductives (king and queen) are the original founders of the colony after a
nuptial flight. Secondary reproductives (neotenics) develop from nymphs within
an established colony when the primary queen’s productivity declines or the
colony becomes very large. They assist or replace the primary queen in egg-
laying.
12. Which termite species is known for building above-ground carton nests
that do not require soil contact? A) Eastern subterranean termite B) Formosan
subterranean termite C) Drywood termite D) Dampwood termite Answer: B)
Formosan subterranean termite (correct answer) Rationale: Formosan
subterranean termites are unique among subterranean species in their ability to
construct above-ground carton nests (aerial colonies) made of chewed wood,
soil, and saliva. These nests can exist entirely within structures without ground
contact, making them particularly difficult to control.
13. What is the approximate time for a subterranean termite colony to reach
maturity and produce swarmers? A) 3-6 months B) 1-2 years C) 3-5 years D)
10-15 years Answer: C) 3-5 years (correct answer) Rationale: Subterranean
termite colonies typically require 3-5 years to develop from a single pair of alates
into a mature colony capable of producing swarmers. Colony development time
depends on species, environmental conditions, and food availability. Formosan
termites may develop slightly faster due to their aggressive nature.
