13-5. The larval and nymph stages are more
likely to transmit microorganisms such
as Lyme disease because they are often
overlooked as a result of their small size.
It takes at least 24 hours of contact
feeding to obtain a good transmission
rate. Adult ticks are sufficiently large that
most people see them quickly and they
are removed before complete transmission
can occur.
13-6. A scutum is the hard plate or shell on the
dorsal surface of a hard tick, such as
Ixodes spp.
13-7. Hemocele—a blood sac or cavity in
which the blood meal is held; found in
the body of blood-sucking arthropods.
Vertical transmission—some arthropod
hosts are capable of transmitting their
infecting microorganism to their progeny,
perpetuating the environmental source of
human infection (e.g., ticks).
Capitulum—the head and mouth parts of
a hard shell tick.
