There are approximately NUMBER species of mosquitos worldwide, most of which are not medically significant.

Why is it important for you to be able to recognize each life stage of the mosquito?

Which statement about the pupa stage of mosquitos is correct?

A) This stage feeds on algae

B) This is the stage in which metamorphosis to adults will occur

C) This stage lasts approximately from two to three days

D) Mosquito pupae can be very active, coming to the surface for air

Which mosquitoes bite?

a. Male mosquitoes

b. Female mosquitoes

c. Both male and female mosquitoes

Mosquitoes lay eggs both _ and _ depending on the species

________ instar mosquito larvae are used in identification.

Adult female mosquitoes__________________.

a. Feed on nectar after emerging from the pupal stage

b. Usually mate only once to fertilize her lifetime supply of eggs

c. Must obtain a protein rich blood meal for each batch of eggs

The main mosquito classifications based on larval habitat are:

a. Permanent water

b. Floodwater

c. Day biters

d. Container

e. Night biters

Floodwater mosquitoes ________________.

a. Lay their eggs in standing water
b. Lay their eggs in stagnant water
c. Lay eggs that need to dry out before hatching
d. Lay their eggs in moist soil

Mosquitoes that develop in floodwater habitats usually become a problem about DAYS TO DAYS after a heavy rain, and subside in about a month or two.

Permanent water mosquitoes prefer to lay their eggs ___________.

a. In quiet bodies of freshwater with sunlight
b. In bodies of water with a good deal of surface vegetation
c. In bodies of water with no surface vegetation
d. In bodies of water with very little wave action
e. In bodies of water with some wave action

Some Culex species prefer _ water.

Some species of permanent water mosquitoes lay eggs that will tolerate

Populations of permanent water mosquitoes:

a. Are typically high in the spring and decline throughout the summer
b. Peak in August, September and sometimes October in warmer areas
c. Are typically low in the spring build up throughout the summer
d. Peak in late April, May, and June

Container mosquitoes encountered by mosquito control professionals are primarily in the genera _ and _

Due to their medical importance, significant types of container mosquitoes are _ and _

Select important characteristics of Aedes albopictus.

a. Aedes albopictus eggs are laid singly on the sides of water-holding containers
b. Aedes albopictus larvae usually pupate after five to ten days
c. Aedes albopictus has largely displaced Aedes aegypti in the southeastern US

important characteristics of Aedes aegypti.

a. Aedes aegypti eggs are desiccation-resistant
b. Aedes aegypti is closely associated with humans and their dwellings
c. Aedes aegypti was introduced into the U.S. through scrap tires from Northern Asia
d. Aedes aegypti are better larval competitors than Aedes albopictus using lower-nutrient, natural resource environments

Mosquito trapping data is used

a. To estimate adult mosquito population densities, species, age structure, and distribution
b. To determine optimal time to conduct control measures
c. To evaluate appropriate treatments
d. For arboviral surveillance

To determine arbovirus prevalence, data derived from mosquito surveillance include

a. Estimates of mosquito species abundance
b. Infection rates in the mosquito populations
c. Mapping potential breeding sites

Larval Surveillance data should include

a. the number of larvae per dip
b. mosquito species
c. stage of development
d. census of persons at potential risk within a 1 mile radius
e. GPS coordinates
f. type and size of breeding area

The standard survey tool for adult mosquito collection is:

Gravid traps use an _ attractant to sample female Culex spp. mosquitoes which have taken a blood meal and are seeking a place to lay eggs.

Mosquito control programs can increase the effectiveness and efficiency of their services by incorporating

The goal of source reduction is to remove the _ that is needed to sustain the mosquitoes’ life cycle.

Examples of organisms used to control mosquito larvae and pupae are

a. Fish
b. Predacious mosquitoes
c. Copepods
d. Praying mantis

Larvicides are categorized as:

Select one or more:
a. Neurological toxins
b. Surface oils and films
c. Bacterial larvicides
d. Organophosphates
e. Insect growth regulators
f. Breeding inhibitors

For adulticides, one of the most significant things to be aware of is:

At a minimum, bioassays should be conducted ___________ to determine if there has been a change in insecticide efficacy.

a. prior to the spray season
b. following the spray season
c. at scheduled intervals during the spray season
d. at intermittent intervals during the spray season

Bottle bioassays and cage tests are used to

Critical components of an effective communication and education of IPM approach to mosquito control include

a. Continuing Education
b. Stewardship
c. Personnel Certification
d. Recordkeeping
e. Permitting

Depending on the temperature and the species, natural disasters will produce increased
mosquito populations in approximately DAYS TO DAYS
