nearby plants and catch on to passing
animals. Some species remain on the
host while they develop from larvae
to adults. Other species drop to
the ground after each blood meal and
molt to the next stage. Fed females
of all species drop to the ground
for egg-laying.

 Control application depends
upon the species of ticks involved.
For those infesting the body, treat
the entire body with high pressure
sprays or dips. Because of the large
number of soecies and various develop-
mental stages, control may be required
at any time during the year.

CATTLE SCABIES

 Mites are tiny versions of the
 tick. Identification of the various
 species causing skin irritation is
 important in determining methods of
 control.

 Psoroptic scabies is the most
 serious form requiring immediate
 quarantine and treatment. The life
 cycle is completed in 10-12 days.

 Sarcoptic scabies are somewhat
 smaller than the common or Psoroptic
 mites. The life cycle requires
 1-4 weeks. Animals must be quaran-
 tined under Federal regulations for
 both. ,


and deposit eggs. These hatch in 1-3
days. The larvae and nymphs either
continue to tunnel or may crawl on
the surface of the skin. The life
cycle is about 2 weeks. Infestation
can cause decreased efficiency.
Treat infested animals by spraying
or dipping them in registered
pesticides.

 Sheep and Goats

 The insects and related pests
that attack sheep and goats include:

SHEEP KED

 The sheep ked adult is a wingless
fly which spends its entire life
cycle on sheep. It is occasionally
found on goats. The nearby mature
larvae are deposited on wool strands,
where they pupate almost immediately.
Twenty-one days later the ked emerges
and begins to take blood meals.
