,Q1. A mosquito control program in Alberta is evaluating a wetland for larviciding.
The target species is Aedes vexans. Which combination of factors would MOST favor
the use of a bacterial larvicide (Bti) over a conventional insect growth regulator
(IGR)?
A. High water temperature and dense vegetation
B. Water pH below 5 and high organic content
C. Presence of non-target invertebrates and need for rapid control
D. Persistent water body with multiple broods
Correct Answer: C. Presence of non-target invertebrates and need for rapid control
Rationale: Bti is highly specific to mosquito larvae and degrades quickly, minimizing
non-target impact. It provides rapid control, whereas IGRs are slower and affect
non-target arthropods. High temperature and organic content affect Bti efficacy but the
primary reason to choose Bti is its target specificity and rapid action.
Why Wrong:
A - High temperature and vegetation affect all larvicides; they do not specifically
favor Bti over IGRs.
B - Low pH and high organic content can reduce Bti efficacy; IGRs may be more
stable under such conditions.
D - Persistent water bodies with multiple broods might favor IGRs due to longer
residual activity.

Q2. In Alberta, the primary vector for West Nile virus (WNV) is Culex tarsalis. A
surveillance program reports a vector index (VI) of 0.75 and an infection rate (IR) of
1.5 per 1,000. Which action is MOST consistent with Alberta's integrated pest
management (IPM) thresholds?
A. Initiate adulticidal fogging in all urban areas
B. Continue surveillance and increase larval control efforts
C. Issue a public health advisory and consider targeted adult control
D. Discontinue control measures due to low risk
Correct Answer: C. Issue a public health advisory and consider targeted adult control
Rationale: Alberta's IPM uses thresholds based on VI and IR. A VI of 0.75 and IR of
1.5/1000 indicates moderate risk, prompting public advisories and targeted adult control,
not widespread fogging or cessation. Larval control alone is insufficient at this risk level.
Why Wrong:
A - Widespread fogging is reserved for high risk (VI > 1.5 or IR > 3.0).
B - Larval control is important but does not address adult vectors already infected.
D - Discontinuing control would ignore the moderate risk indicated by the thresholds.

Guidelines.
Q3. A novel mosquito control agent is being tested that targets the larval midgut by
binding to a specific receptor. The agent is effective against Aedes and Culex but not
against Anopheles. Which molecular mechanism is MOST likely responsible for this
species specificity?
A. Differences in the peritrophic membrane thickness
B. Variation in the receptor's amino acid sequence
C. Differential expression of detoxification enzymes
D. Differences in larval feeding behavior
Correct Answer: B. Variation in the receptor's amino acid sequence
Rationale: Species-specific toxicity of midgut-acting toxins (e.g., Cry toxins) is primarily
due to the presence and structure of specific receptors (e.g., cadherin-like proteins) in the
midgut. Amino acid sequence variations alter binding affinity, leading to differential
susceptibility among species.
Why Wrong:
A - Peritrophic membrane thickness can affect toxin penetration but is not the primary
determinant of receptor-mediated specificity.
C - Detoxification enzymes may influence resistance but not the inherent species
specificity of a toxin.
D - Feeding behavior affects exposure but not the molecular specificity of the
toxin-receptor interaction.
Reference: Lacey, L.A. (2017). Microbial Control of Insect and Mite Pests, Ch. 3.
Q4. A mosquito control district is applying a permethrin-based adulticide. Which
tank-mix additive would MOST likely enhance the insecticide's efficacy while
reducing resistance selection pressure?
A. Piperonyl butoxide (PBO)
B. Mineral oil
C. Sodium chloride
D. Atrazine
Correct Answer: A. Piperonyl butoxide (PBO)
Rationale: PBO is a synergist that inhibits cytochrome P450 enzymes, which are involved
in metabolic resistance. By blocking these enzymes, PBO increases the toxicity of
permethrin, allowing lower doses and reducing selection pressure for resistance.
Why Wrong:
B - Mineral oil is a surfactant/spreader, not a synergist.
C - Sodium chloride has no effect on insecticide activity.
