SECTION 1: PEST IDENTIFICATION & BIOLOGY
QUESTION 1
Which of the following insects is classified as a true bug with piercing-sucking
mouthparts?
A) Housefly
B) Cockroach
C) Bed bug
D) Ant
,E) Mosquito
CORRECT ANSWER: C) Bed bug
RATIONALE: Bed bugs are true bugs (Order Hemiptera) characterized by piercing-
sucking mouthparts that they use to extract blood from hosts. Houseflies have
sponging mouthparts, cockroaches have chewing mouthparts, ants have chewing
mouthparts, and mosquitoes have a proboscis designed for piercing skin and
sucking blood but are not classified as true bugs in the Hemiptera order.
QUESTION 2
What is the primary characteristic that distinguishes insects from other
arthropods?
A) Presence of a segmented body
B) Presence of exactly three pairs of legs in the adult stage
C) Ability to undergo metamorphosis
D) Presence of an exoskeleton
E) Capacity to reproduce sexually
CORRECT ANSWER: B) Presence of exactly three pairs of legs in the adult stage
RATIONALE: All insects in their adult form possess exactly six legs (three pairs),
which is the defining characteristic that separates them from other arthropods like
arachnids (eight legs), crustaceans, and others. While insects have segmented
bodies and exoskeletons, these features are shared with other arthropods. Not all
insects undergo metamorphosis, and reproduction methods vary across different
pest species.
QUESTION 3
The German cockroach (Blattella germanica) completes its life cycle from egg
to adult in approximately how many days under optimal conditions?
,A) 7 to 10 days
B) 15 to 20 days
C) 30 to 40 days
D) 60 to 90 days
E) 120 to 150 days
CORRECT ANSWER: D) 60 to 90 days
RATIONALE: German cockroaches have a relatively rapid reproduction cycle of 60
to 90 days under ideal conditions (warm, humid environments), though this can
vary. This quick life cycle allows their populations to explode rapidly if not
controlled, making early detection and intervention critical for pest management.
The other timeframes do not accurately reflect German cockroach development.
QUESTION 4
Which pest produces frass (fecal pellets) that appears similar to sawdust or
powder?
A) Termite
B) Carpenter ant
C) Powderpost beetle
D) Carpenter bee
E) Dust mite
CORRECT ANSWER: C) Powderpost beetle
RATIONALE: Powderpost beetles (Family Bostrichidae and Lyctidae) produce fine,
powdery frass that resembles sawdust or flour, which is a key identifying
characteristic when inspecting wood damage. Termites produce different frass
compositions, carpenter ants leave coarser debris, carpenter bees create smooth
tunnels, and dust mites don't produce frass in the traditional sense.
, QUESTION 5
What is the complete metamorphosis pattern called when an insect goes
through egg, larva, pupa, and adult stages?
A) Incomplete metamorphosis
B) Holometabolous development
C) Simple metamorphosis
D) Gradual metamorphosis
E) Partial transformation
CORRECT ANSWER: B) Holometabolous development
RATIONALE: Holometabolous development refers to complete metamorphosis
with four distinct life stages: egg, larva, pupa, and adult. This is in contrast to
hemimetabolous development (incomplete metamorphosis), which skips the pupal
stage. Flies, beetles, moths, and fleas all undergo holometabolous development.
QUESTION 6
The common house mosquito (Culex pipiens) typically breeds in which type of
water source?
A) Fast-moving streams
B) Stagnant water in containers and gutters
C) Chlorinated swimming pools
D) Running faucet water
E) Distilled water
CORRECT ANSWER: B) Stagnant water in containers and gutters
RATIONALE: Culex mosquitoes prefer stagnant water environments such as
clogged gutters, abandoned containers, birdbaths, and other areas with minimal
water movement. They will not develop in flowing water, heavily chlorinated pools,
