,Section A - Mosquito Biology AND Identification
Q1.
A surveillance program in southern Alberta uses CO2-baited CDC light traps and gravid
traps. Which combination of trap data best estimates the risk of West Nile virus (WNV)
transmission to humans?
A. Proportion of Culex tarsalis females that B. Total number of Aedes vexans females
are parous and daily survival rate and minimum infection rate (MIR)
C. Species diversity index and larval habitat D. Ratio of Culiseta inornata to Culex
density restuans and weekly precipitation
Correct: A - Proportion of Culex tarsalis females that are parous and daily survival rate
Rationale:Parity and daily survival rate directly indicate the proportion of females old enough
to have completed extrinsic incubation and transmit WNV. Total Aedes counts (B) are less
relevant as they are not primary WNV vectors. Diversity indices (C) and precipitation (D) are
indirect and less predictive.
Q2.
A larval control program applies Bacillus thuringiensis israelensis (Bti) to a floodwater
mosquito habitat. Which ecological factor most limits the residual efficacy of Bti?
A. High water temperature (>25°C) B. UV radiation breaking down the
accelerating degradation of the toxin spore-crystal complex within hours
C. Alkaline pH (>8.5) denaturing the Cry D. Competitive inhibition by native microbial
proteins flora in the water column
Correct: B - UV radiation breaking down the spore-crystal complex within hours
Rationale:Bti's spore-crystal complex is highly susceptible to UV degradation, reducing
residual activity to less than 24 hours in exposed water. High temperature (A) may enhance
degradation but is less critical than UV. pH (C) within typical field ranges does not denature
Cry proteins. Microbial competition (D) is not a significant limitation.
Q3.
In an area with confirmed pyrethroid resistance in Aedes vexans, which rotation strategy
would most effectively delay the evolution of resistance?
A. Alternate between two pyrethroids with B. Use a pyrethroid for one complete
different chemical structures each season, then switch to an organophosphate
generation the next season
Page 3
, Section A - Mosquito Biology AND Identification
C. Apply a mixture of pyrethroid and a D. Rotate among three unrelated insecticide
synergist (piperonyl butoxide) at every classes (e.g., pyrethroid, organophosphate,
treatment spinosyn) within a single season
Correct: B - Use a pyrethroid for one complete season, then switch to an
organophosphate the next season
Rationale:Rotating between classes annually reduces selection pressure from a single mode
of action, slowing resistance evolution. Alternating pyrethroids (A) does not address
cross-resistance. Mixtures (C) can delay resistance but risk dual resistance if not carefully
managed. Within-season rotation (D) may not allow resistance alleles to decline sufficiently.
Q4.
A mosquito control district is evaluating a new adulticide application technology that
produces ultra-low volume (ULV) droplets with a volume median diameter (VMD) of 15 µm.
What is the primary disadvantage of this droplet size for mosquito control?
A. Excessive evaporation before reaching B. Poor penetration through vegetation and
target mosquitoes canopy
C. Increased non-target deposition on water D. Rapid sedimentation due to gravitational
surfaces settling
Correct: A - Excessive evaporation before reaching target mosquitoes
Rationale:Droplets of 15 µm are very small and have high surface-area-to-volume ratio,
leading to rapid evaporation, especially in low humidity. This reduces the number of droplets
that remain airborne and contact mosquitoes. Penetration (B) is better with smaller droplets.
Non-target deposition (C) and sedimentation (D) are less of an issue with small droplets.
Q5.
Which mosquito species in Alberta is most likely to be a bridge vector for WNV, exhibiting
both ornithophilic and mammophilic feeding behavior?
A. Ochlerotatus (Aedes) flavescens B. Culex tarsalis
C. Anopheles earlei D. Culiseta morsitans
Correct: B - Culex tarsalis
Rationale:Culex tarsalis is a primary WNV vector that feeds readily on birds (ornithophilic)
and mammals (mammophilic), making it an effective bridge vector from avian reservoirs to
humans. A. flavescens is primarily mammophilic. Anopheles earlei and C. morsitans are less
involved in WNV transmission.
