insecticide proteins
What are some facts about the giant silk moth? - Answer- the male can detect a female
a mile away, bolas spiders mimic the pheromones of the giant silk moth for males to
follow to the spider to be eaten, adult moths cannot eat they die after laying their eggs
two weeks later
What do kissing bugs do? - Answer- they carry a parasite that causes chagas disease

What are Africanized honey bees? - Answer- honey bees that demonstrate aggressive
nature and other undesirable characteristics of African honey bees. Dominantly
inherited when these bees mate with European strain honeybees. First released
(accidentally) in Brazil in 1956, they are now found on the Southern border of the US.
What is an agent? - Answer- a living organism causing disease in an arthropod
, What is a reservoir? - Answer- maintains a disease on the landscape over long periods
of time
What is a vector? - Answer- an organism that transmits that agent from an infected
reservoir/host to a non-infectedhost
What is a disease? - Answer- a negative consequence of acquiring that agent in an
affected host
what is biological transmission? - Answer- when the agent goes through some part of its
life cycle in the vector
what is mechanical transmission? - Answer- when the agent hitches a ride
what is lyme disease caused by? - Answer- spiraquite bacteria
what is the vector for lyme disease? - Answer- black leg deer tick
what is the reservoir for lyme disease? - Answer- deer mice
what are the symptoms of lyme? - Answer- fever, muscle aches, joint pain, bulls eye
rash
what can lyme be treated with? - Answer- antibiotics
what bacteria causes rocky mountain spotted fever? - Answer- rickettsia bacteria
what is the vector for rocky mountain spotted fever in NC? - Answer- American dog tick
what is the reservoir for rocky mountain spotted fever? - Answer- raccoon
what are symptoms of rocky mountain spotted fever? - Answer- high fever, severe
headache, pinpoint rash (tiny red spots that start at wrist and go onto the trunk)
T/F: if rocky mountain spotted fever goes untreated it can be fatal and cause brain
damage? - Answer- true
what can rocky mountain spotted fever be treated with? - Answer- antibiotics
what is the number one state rocky mountain spotted fever is seen in? - Answer- NC
