CHAPTER 13 The Arthropods
Quick Quiz! 13-30
How do cockroaches affect the health of humans?
(Objectives 13-6 and 13-8)
A. They transmit diseases during a blood meal on the
human host.
B. They are capable of vertical transmission of rickettsial
diseases.
C. They carry and transmit diseases by mechanical
transfer to uncovered food.
D. None of the above.
LOOKING BACK
Each of the arthropods discussed in this chapter
is responsible for transmitting one or more parasites,
as summarized in Table 13-13. In addition,
each arthropod may also be the source of human
infestation independent of its parasite-transmitting
capabilities. In addition, each arthropod
may also be the source of human infestation or
illness independent of its parasite-transmitting
capabilities. Thus, accurate identification of these
arthropods is crucial to treat, prevent, and
control infections.
Proper identification of the arthropods
described in this chapter requires careful inspection
of the head, thorax, and abdominal regions.
Although these organisms are visible to the naked
eye, microscopic examination may be helpful to
confirm the identification and for speciation.
Comparison drawings of the arthropods discussed
are shown at the end of this chapter. These
will serve as a visual summary of the arthropods’
key features.
