MOSQUITO SURVEYS
a. General. Mosquito surveys are essential to determine the species present,
their abundance, their potential hazard in transmitting disease, and to collect information
on which to base an efficient control program. Two types of mosquito surveys are
widely used.
(1) The original basic survey determines the species, source, location,
densities, and flight range of mosquitoes.
(2) The operational survey is a continuing evaluation which is extremely
valuable in the daiIy operation of a mosquito control program, providing information on
the effectiveness of control operations, and data for comparison throughout a season or
from year to year. Equipment for mosquito surveys are shown in figure 3-1.
b. Maps. A good map of the area to be surveyed is the first requirement. A
sample map is shown in figure 3-2. The map should show, as a minimum, the location
of Iight traps, resting stations, biting stations, and larval breeding sites. A complete
description of each of the above sites should be prepared separately from the map to
include all pertinent information such as, "Biting Station Number 1 is located behind the
gristmiII at the crossroads of Smith Road and Foster Road." The importance of these
maps cannot be overemphasized. They should be kept up to date at all times and
reviewed on a continuing basis.
c. Larval Surveys. Mosquito larval dipping stations can be anywhere water
stands. It can be anything from a lake to a tree hole. Common larval dipping stations
are small pools in wooded areas, barrels and other containers, open ditches and drains,
and even truck tire tracks on unpaved roads. Most larval collections are done with the
white enamel dipper and the number of larvae taken at each station is recorded as
