Tracheal Mite Quiz
ANSWERS
Tracheal Mites(Acarapis woodi) a Microscopic Parasite
1.
Mites, ticks, insects, crayfish, lobsters,spiders and honey
bees(insects) all belong to the
Phylum--------Arthropoda-------------.
2.
Unlike insects with their six set of legs(3 pair) mites have
---8---legs or -----4---pair of legs.
3. Adult insects including
the honey bee have 3 main body parts,head, thorax and abdomen, on the
other hand mites have only 2 main body regions, the head region is
called the gnathosoma and the the other region the idiosoma which
contains the---legs-----and the----genitalia----of the mite.
4.Tracheal mites were
first found to be present in the Americas in the early 1980's in
what county-----Mexico-------.
5.These mites feed, mate
and reproduce in the tracheae(respiratory passages) of (circle one
of the following), young larval, pupae, or primarily
young adult bees.
6.Mature tracheal
mites(females) emerge from their host and seek young(callow)
bees usually------- under 3 days of age ------ days old.
7. While residing
inside the tracheae, mites not only mate and produce their
offspring, but injury their host by feeding on
their-----hemolymph------ and while doing so damage the bee's
------breathing------apparatus.
8. Mite counts are
usually low during the summer season as infected bees with a
short life span(5 to 6 weeks) die taking their mites to the grave
with them. However some time starting in mid summer, bees develop
that are referred to as summer bees with an extended longevity,
these bees carry their parasites with them into their winter
cluster, here their concentration intensifies and the colony is
likely to be -----weaken-------or die off as a consequence
9. Tracheal mites infect all members of a bee colony which
include----workers----, -----queens-------, and------drones------.
10. Although we know somewhat more about the female
tracheal mite and her activities very little is known about the------male-------mite.
11. When dissecting a bee for the presents of mites, a health
non infested trachea will be -----creamy white or clear and
translucent-------in color.
12. There are at least 3 methods
by which mites are dispersed, drifting of workers and drones,
robbing and by
-------the close proximity
of one bee to another-----.
13. Mature female mites exit the tracheal system only to reenter
the tracheal system of another----bee-------.
14.
External signs of the presents of mites in bees include,a dwindling
bee population,weak bees crawling on the ground, bees with K wing,
piles of dead bees in front of the hive and an abandoned hive with
plenty of honey stores,yet only an internal examination of the
trachea may reveal that the ------tracheal mites---------(two words)
are responsible for the observations one witnesses.
15. Tracheal mites can be controlled with several
different chemicals: list four different
chemicals that
can be used to control these mites,(a)------ Apilife
var-----,(b)--------formic acid-------,(c)-----menthol-------and
(d)-------oil patties------. Remember when using chemicals in your
bee colonies strictly follow ALL instruction on the labels.
16. Mature female tracheal mites only lay their eggs
inside the first pair of -------tracheae------tubes located on the
bees----prothorax----(give body part).
17.When male and female mites mate they do so (circle one), on
any external part of the bee, somewhere on the bees antennae, areas
yet to be defined, inside
the bee's tracheae.
18. Heavy infestations of tracheal mites are most likely to be
found in the fall and early in the spring, please provide a short
answer as to why.: .-----------------------bees
are clustered together thus easy for mites to transfer from one bee
to another-.
19. Since some of the chemicals used for varroa mites also
are effective for use on tracheal mites, when one treats for either
mite one may also in effect have treated for the other if the time
of the year is nearly the same. True
or false(circle one)
