ENTOMOLOGICAL SURVEY REPORT
The entomological survey report provides information necessary to conduct an
arthropod control program. Specific detaiIs such as the location of the arthropod
specimens, as well as the identification and the medical importance of the specimens
are included in this report. Figure 3-12 shows the general format of an entomological
survey report.
3-10. THE SURVEY MAP
a. When preparing the survey map, bear in mind that you are the eyes of those
who will have to come in and control what you find. Remember that they will often be
completely unfamiliar with the surveyed area. Be neat and use a standard method for
marking breeding sites. A proven method is to place site numbers in a distinct
geometric shape. The site numbers are placed on the map as close to the actual site
as possible. For example, mosquito adult resting stations might be represented by
numbers in triangles; larval dipping stations by numbers in circles; light trap sites by
numbers in squares; and so forth.
b. Progressive numbers should be used starting at number 1 and continuing--
number 2, number 3, number 4, and so forth. Regardless of how many sites are
located, or even if they harbor the same category of arthropods, use a single number for
each. These same numbers are used for your data sheet(s). If you mark an area 3 on
your map, Item 3 on your data sheet will reflect what was found there. The survey map
is attached to your report as an annex.
c. Notice the number 1 on the survey map provided (see figure 3-13). The legs
of the triangle have been extended. This is done when you wish to emphasize that a
large area is infested with a specific category of arthropods. By measuring the length of
these lines and checking the scale of the map, the control team can determine exactly
the area to be controlled.
d. When possible, two maps of each site should be prepared. One map should
be prepared for mosquitoes (mature and immature stages) and another for the other
arthropods surveyed (see figure 3-14).
e. Maps should also be prepared of all facilities where you conduct cockroach
surveillance. Make a master copy for each building, then photocopy as needed. The
location of sticky traps can then be recorded to ensure all traps are accounted for.
Additionally, you can prepare a map with the numbers of cockroaches captured at each
site placed at the site location. This is very useful for directing spot treatments.
