,Q1. A mosquito control program in an urban area detects West Nile virus (WNV) in
Culex quinquefasciatus. Historical data show WNV transmission peaks when vector
infection rate exceeds 1 per 1,000. The current infection rate is 2.5 per 1,000, and
mosquito abundance is rising. Which intervention strategy is most appropriate as the
primary response?
A. Defer adulticiding until human cases are confirmed to reduce insecticide exposure.
B. Focus exclusively on larval source reduction to avoid resistance development.
C. Implement targeted ultra-low volume (ULV) adulticiding in areas with high vector
infection and abundance.
D. Increase public education campaigns and delay chemical control until infection rate
reaches 5 per 1,000.
Correct Answer: C. Implement targeted ultra-low volume (ULV) adulticiding in areas
with high vector infection and abundance.
Rationale: Targeted ULV adulticiding is recommended when vector infection rates and
abundance indicate imminent transmission risk, as it rapidly reduces adult mosquito
populations. Larval source reduction is important but may not act quickly enough; waiting
for human cases or higher infection rates increases outbreak risk. Public education is
secondary to immediate vector control.
Why Wrong:
A - Deferring adulticiding until human cases occur allows virus amplification and
increases human exposure.
B - Larval source reduction is essential but insufficient alone for rapid epidemic
response.
D - Delaying action until infection rate reaches 5 per 1,000 exceeds the established
threshold and escalates risk.

Mosquito-Borne Disease Surveillance and Response.
Q2. An IPM program for rodent control in a municipal sewer system is facing bait
aversion in Norway rats (Rattus norvegicus). Which strategy is most effective to
overcome aversion and improve long-term control?
A. Double the concentration of the current anticoagulant bait.
B. Switch to a single high-dose acute toxicant without prebaiting.
C. Rotate to a different chemical class of rodenticide and use pulse baiting.
D. Eliminate all baiting and rely solely on trapping.
Correct Answer: C. Rotate to a different chemical class of rodenticide and use pulse
baiting.
Rationale: Bait aversion often results from sublethal exposure to an anticoagulant.
Rotating to a different chemical class (e.g., from a first-generation to a second-generation
Page 3
, anticoagulant or a non-anticoagulant) and using pulse baiting reduces the likelihood of
aversion and improves acceptance. Doubling concentration may increase toxicity but not
palatability. Acute toxicants without prebaiting often cause bait shyness. Trapping alone is
insufficient for large sewer infestations.
Why Wrong:
A - Increasing concentration does not address the behavioral aversion to the bait
matrix.
B - Acute toxicants without prebaiting frequently induce bait shyness.
D - Trapping is labor-intensive and rarely achieves population reduction in sewers.
Reference: NCSU Public Health Pest Control Manual, Rodent Control Chapter.
Q3. A new insecticide exhibits a high log P (octanol-water partition coefficient) and
low water solubility. How will these physicochemical properties most likely affect its
environmental fate and efficacy in mosquito larvicide applications?
A. Rapid degradation in water due to high solubility.
B. Persistence in aquatic sediments and potential biomagnification.
C. Reduced efficacy against mosquito larvae due to poor cuticular penetration.
D. Increased volatility leading to rapid atmospheric dissipation.
Correct Answer: B. Persistence in aquatic sediments and potential biomagnification.
Rationale: High log P indicates lipophilicity, causing the compound to partition into
organic matter and sediments, increasing persistence and potential for biomagnification in
food chains. Low water solubility limits degradation in water column. Lipophilicity
enhances cuticular penetration in insects, not reduces. Volatility is not directly predicted
by log P.
Why Wrong:
A - Low water solubility means slow degradation in water, not rapid.
C - Lipophilic compounds typically penetrate insect cuticle well, enhancing efficacy.
D - Log P does not predict volatility; vapor pressure is the key factor.
Reference: Pesticide Environmental Fate and Toxicology, NC State Extension.
Q4. During a public health pesticide application, a technician notices that the spray
tank pressure is fluctuating and the nozzle output is inconsistent. Which component is
most likely malfunctioning and requires immediate inspection?
A. Nozzle strainer
B. Agitator
C. Pressure regulator
D. Spray gun gasket
Correct Answer: C. Pressure regulator
