Mosquito License Exam) – Q&A
The genus of mosquito having palps roughly as long as the proboscis is:
a. Aedes
b. Culex
c. Anopheles ✔️Ans - Anopheles
Mosquito larvae breathe: ✔️Ans - Through respiratory openings near
the tip of the abdomen
Some mosquitoes lay their eggs: ✔️Ans - On damp soil
The number of mosquito species in Michigan is approximately: ✔️Ans -
60
The three classes of Michigan mosquitoes, based on breeding sites, are:
✔️Ans - Floodwater, permanent water, and container/tree hole mosquitoes
Insects that are often confused with mosquitoes are: ✔️Ans - Midges
Which potential pathogens contracted from mosquitoes are most
concerning in Michigan? ✔️Ans - West Nile virus (WNV), St. Louis
encephalitis (SLE), La Crosse encephalitis (LAC) and eastern equine
encephalitis (EEE).
What family do mosquitoes belong to? ✔️Ans - Culicidae
The three egg laying patterns ✔️Ans - - eggs laid singly on the water
surface - eggs glued together to form rafts that float on the water surface
- eggs laid singly out of the water
Anopheles eggs... ✔️Ans - Have lateral extensions that serve as floats
Culex eggs ✔️Ans - Culex, Culiseta, Coquillettidia and Uranotaenia
species glue individual eggs together to form floating rafts of up to 300
eggs or more.
, Aedes eggs ✔️Ans - The eggs of Aedes, Psorophora and Orthopodomyia
species are deposited individually out of the water, and they are adapted to
withstand desiccation (being dry) until the area is later flooded and the
eggs hatch.
Siphon ✔️Ans - An air tube
The time it takes mosquitoes for complete larval Development in
mosquitoes ✔️Ans - The time for complete larval development at
normal summer temperatures in Michigan is from five to 10 days but may
be much longer at lower temperatures.
How many segments on an adult mosquitoe? ✔️Ans - 15, only 14 are
visible
Antennae are believed to be organs of... ✔️Ans - Hearing and smelling
This genus appears to be the major vectors of WN and SLE in the United
States. ✔️Ans - Culex
How is EEE different from SLE and WN? ✔️Ans - EEE differs from SLE
and WN in that it is primarily a rural disease centered near freshwater
swamps.
The human age group most likely to have severe symptoms from La Crosse
encephalitis (CE group) are:
a. Children
b. Teenagers
c. Older adults ✔️Ans - Children
A "dead-end host" is one that:
a. Causes the death of the mosquito vector
b. Always dies after receiving a pathogen from a vector
c. Is outside of the natural transmission cycle of the virus ✔️Ans - Is
outside of the natural transmission cycle of the virus
SLE and WN disease are caused by viruses that have a natural transmission
cycle involving several species of:
a. Wild birds
