Question 1
What is the primary purpose of Integrated Pest Management (IPM) in structural
pest control?
A. Eliminate all pesticide use entirely
B. Use only chemical pesticides for fast results
C. Combine multiple pest control methods to reduce pest populations
economically and safely
D. Focus only on biological control agents
Answer: A. Eliminate all pesticide use entirely
Rationale: IPM does not aim to eliminate pesticide use completely; instead, it
integrates multiple control strategies such as cultural, mechanical, biological,
and chemical methods. The goal is to manage pest populations at acceptable
levels while minimizing risks to humans, property, and the environment. Option
A is incorrect because IPM does not prohibit pesticides entirely, only encourages
responsible and minimal use when necessary.
,Question 2
Which pest is most commonly associated with structural wood damage in
buildings?
A. Ants
B. Termites
C. Cockroaches
D. Fleas
Answer: B. Termites
Rationale: Termites are the most destructive structural pests because they feed
on cellulose in wood, often causing hidden damage over long periods.
Subterranean termites are especially problematic in buildings. While ants,
cockroaches, and fleas are nuisance or health pests, they do not typically cause
major structural wood damage like termites do.
Question 3
What is the most effective way to prevent rodent infestations in industrial
buildings?
A. Routine fogging with insecticides
B. Removing all lighting around the structure
C. Sealing entry points and eliminating food and water sources
D. Using sweet baits only indoors
Answer: C. Sealing entry points and eliminating food and water sources
Rationale: Rodent prevention relies primarily on exclusion and sanitation.
Sealing cracks, holes, and gaps prevents entry, while removing food and water
sources reduces attraction. Chemical control alone is not sufficient for long-term
prevention. Fogging and baiting may reduce populations but do not prevent
reinfestation without structural and sanitation measures.
,Question 4
Which class of pesticides is most commonly used for insect control in structural
pest management?
A. Rodenticides
B. Herbicides
C. Insecticides
D. Fungicides
Answer: D. Fungicides
Rationale: Fungicides are primarily used to control fungal diseases, not insects.
Structural pest control for insects relies on insecticides, which are specifically
designed to target insect nervous systems or growth processes. Rodenticides
target rodents, herbicides target plants, and fungicides target fungi, making D
incorrect.
Question 5
What is the main reason pesticide resistance develops in pest populations?
A. Overuse of biological controls
B. Repeated use of pesticides with the same mode of action
C. Lack of pest reproduction
D. Use of clean water in mixing
Answer: B. Repeated use of pesticides with the same mode of action
Rationale: Resistance develops when pests are repeatedly exposed to the same
chemical mode of action, allowing naturally resistant individuals to survive and
reproduce. Over time, the population becomes harder to control. Biological
controls and water quality do not directly cause resistance. Proper rotation of
pesticide classes helps delay resistance development.
, Question 6
Which pest is a known vector of disease in institutional settings?
A. Housefly
B. Carpenter bee
C. Lady beetle
D. Praying mantis
Answer: A. Housefly
Rationale: Houseflies are mechanical vectors of disease because they feed on
decaying organic matter and then contaminate food and surfaces with
pathogens. They are commonly associated with gastrointestinal diseases in
institutional environments. The other insects listed are not significant disease
vectors in such settings.
Question 7
What is the most important factor when selecting a pesticide for structural pest
control?
A. Color of the pesticide formulation
B. Cost alone
C. Label directions and site approval
D. Popularity among other applicators
Answer: C. Label directions and site approval
Rationale: The pesticide label is a legal document that dictates where and how a
product can be used. Selection must always follow label instructions and ensure
the product is approved for the intended site. Cost, appearance, or popularity
are not valid selection criteria under regulatory standards.
