DOMAIN I: ADVANCED PEST BIOLOGY & IDENTIFICATION (Questions 1-20)
Q1. An inspection of a pharmaceutical warehouse reveals small, flattened,
reddish-brown beetles with 11-segmented antennae ending in a 3-segmented club.
Larvae are found inside sealed cardboard boxes. The pest is most likely:
A. Tribolium castaneum (Red Flour Beetle)
B. Cryptolestes ferrugineus (Rusty Grain Beetle)
C. Lasioderma serricorne (Cigarette Beetle)*
D. Trogoderma variabile (Warehouse Beetle)
Correct Answer: C
Key Competencies: Stored product pest diagnostics; morphological identification.
Scenario Deconstruction: "Flattened" is misleading; Cigarette beetles are oval and
humped. Key diagnostic: 11-segmented antennae with serrated (saw-like) club. Larvae
are internal feeders in packaged goods.
Evidence-Based Justification: Cigarette beetles are major pests of stored tobacco,
spices, and pharmaceuticals. Confirmation requires examination of antennae. Red flour
,beetles (A) have antennae that gradually enlarge. Rusty grain beetles (B) are slender
with long antennae. Warehouse beetles (D) have larvae with distinctive long hairs.
Consequences of Error: Misidentification leads to incorrect treatment focus (surface vs.
product infestation) and potential regulatory action in a pharmaceutical facility.
Professional Insight: Use pheromone traps specific to Lasioderma for monitoring.
Control requires source elimination (infested products), sanitation, and possibly
controlled atmosphere or fumigation.
Q2. A client reports large, black ants emitting a formic acid odor when crushed, nesting
in a wall void near a bathroom leak. Workers are polymorphic. The species and critical
management focus is:
A. Tapinoma sessile (Odorous House Ant); moisture correction and baiting.
B. Camponotus pennsylvanicus (Black Carpenter Ant); locate and eliminate the parent
colony (often outdoors) and correct moisture issues.*
C. Formica subsericea (Field Ant); perimeter spray.
D. Crematogaster spp. (Acrobat Ant); void injection.
Correct Answer: B
Key Competencies: Carpenter ant biology; differentiating moisture-related wood
invaders.
Scenario Deconstruction: Large, black, polymorphic, formic acid odor, associated with
moisture = classic carpenter ant. Bathroom leak indicates a satellite colony.
Evidence-Based Justification: Carpenter ants excavate wood for nesting, unlike termites
that consume it. Management requires finding the parent colony (often in a tree, stump,
,or structural wood) and eliminating it, along with correcting moisture that attracts them.
Simply treating the satellite colony (void injection) will fail.
Consequences of Error: Treating as a nuisance ant (A, C, D) leads to recurring
infestations and continued structural damage.
Professional Insight: Use a moisture meter and thermal camera to trace the moisture
trail and locate nests. Follow foraging trails at night. Insecticidal dusts (e.g., desiccants)
applied to nest galleries are often more effective than sprays for colony elimination.
Q3. During a quarterly inspection of a museum, you observe tiny (1-2 mm), soft-bodied,
wingless insects in a herringbone pattern on the surface of historical documents. They
jump when disturbed and show evidence of surface grazing on the paper fibers. The
primary pest is:
A. Lepisma saccharina (Silverfish)
B. Thermobia domestica (Firebrat)
C. Liposcelis bostrychophila (Booklouse)
D. Entomobrya spp. (Springtail)*
Correct Answer: D
Key Competencies: Micro-pest identification; damage assessment on sensitive
materials.
Scenario Deconstruction: Size, soft body, jumping behavior (furcula), and surface
grazing pattern indicate Collembola. Herringbone pattern is characteristic of springtail
aggregation. Silverfish and firebrats leave irregular holes and scales, not surface
grazing. Booklice do not jump.
, Evidence-Based Justification: Springtails require high moisture and feed on microscopic
fungi. Their presence indicates humidity issues (>70% RH) conducive to mold growth,
which damages documents. They are not typical stored-product pests but indicate
environmental conditions that support other degradative processes.
Consequences of Error: Treating with residual insecticides (appropriate for silverfish)
risks chemical damage to artifacts and fails to address the moisture/fungal issue
driving the infestation.
Professional Insight: Implement climate control (dehumidification to <50% RH) and
HEPA vacuuming. Never apply liquid pesticides near archival materials. Monitor with
sticky traps and hygrothermographs.
Q4. A multi-unit apartment complex reports bed bug complaints in 40% of units
following a recent tenant turnover. Inspection reveals mixed life stages concentrated
around sleeping areas, with fecal spotting on mattress tags but no aggregations along
ceiling junctions. The primary dispersal mechanism and strategic priority is:
A. Phoretic transport on clothing; focus on resident education.
B. Active harborage-seeking migration through wall voids and electrical conduits;
prioritize infrastructure treatment and unit-to-unit barrier placement.*
C. Introduction via used furniture; inspect incoming items only.
D. Natural outdoor migration; perimeter treatment required.
Correct Answer: B
Key Competencies: Bed bug behavioral ecology; multi-unit housing IPM strategy.
Scenario Deconstruction: High infestation rate across multiple units suggests
established infestation spreading through structural voids rather than individual
introductions. Concentration at sleeping areas indicates active feeding sites. Absence
