The grub I'm sheep is the larva Of the
fly ocstrus o,is This fly IL % member
Of a numerous genus, ard belongs To
the order of osfridcd.
Some OF It's cofgenus are, Ocstrus tqui,
the common gad-fly, or nit-fiy that In
fest the horse, and causes the grubs or
bots that infest the stomach OF that an
imal, where its ravages sometimes
cause death.
Another species, less common, but
more tormenting 10 the horse, Is the
0eafj.us hnernOTrhdidaiis, which de-
posts It's eggs on the lips ana edges OF
i Inc victims nOstrils. This latter spe-
cies Is very singular in It's habits To the
OcsfrHs oUi8.
Another species of this order, IL the
ocstrn6 b0pig, the common gad-ny OF
the OK; the eggs Of which are deposited
/ by Che fly In the skin Of IL victim,
from which pisi,n, in short time,
I hey emerge, fall TO the ground, and
either burrow into the earth or con-
Z cml themselves under stones, etc,
! where they remain until sufficiently
7 developed, On month or six weeks Tor
! further propagation Of the species.
! But the nsfrus oUis does not choose the
/ stomach or baek Of It's bearer ~ an in
| cubatory, or more properly speaking,
nursery ,--as this il the only species OF
| this order that IL viperous-but the
! larva Of this insect Is deposited by the
| parent fly in the sleeps nostrils. This
! species appears 10 be confined to the
I sheep and reindeer.
! AS before stated the psfrus Oris de-
| posts It's larya In the noetrils Of the
| sheep. where they fasten themselves
| and retain their position by holding
! on by two cephalic hooks, and AZ they
! develop move farther up into the era
! nial sinuses, where they remain until
they have perfected this stage of lar
val development.
While this stage OF development il
! being attained, the sheep suffers in
| tense torments, and the death of the
! animal IL sometimes n result Of the In
! flammaiory action caused by the irri-
tating presence Of this parasite. This
condition, among stock raisers, is de-
nominated grub In the head" aud
many of them assert that thc9c
''grubs" ultimately find Judgment in
the brain The larya passes from the
nasal sinuses To the ground and there
conceal themselves for u period of six
or eight weeks.
AT the expiration of this period the
lid Of the cocoon Is raised, and the I'M
sect prisoner makes it, escape, and set
about operation for the continuance Of
the species, aud as they ARE neither
furnished with mouth nor other
means Of taking in nourishmeut, 1t
must be extremely short time during
their winged state.
When the fly is full-grown they are
about ilve-twelfths of an inch in
length head grayish, and their body
of an ash color with elevated black
points; abdomen yellewish, and fine
~ spotted with brown or black legs
pule brown; and the wings transpa-
rent; and is capable of holding over
three hundred living larv;c.
AS TO the prevention of the ravages
OF this pestiferous insect-thc OestJtts
oris-much depends upon the environ
mcnt of the flock. When the sheep
rniser is so situated that he can shift
his flock from one field to another and
cultivate, or even fallow-plow his graz
ing land, during the early
| June in Texas ---- he may do
tormentor of Mis- flocks.
| lands their noses may be smcarod
with pine tar, once Il week during the
propogating season of the ily-say
| May and June.
| When the disease has reached its
| highest point the animal loses flesh,
falls down frequently, grinds its teeth,
rolls its redeemed eyes, aud finally
dies on the fourth to the eighth day.
| In mild cases recovery takes place UNI
aided the larva are thrown out along
with the mucus 10y frequent sneeZing.
| The best means for their dialodgeinent
III, first, TO cause the flock to inhnle the
smoke from burning tobacco stems.
A convenient way 10 do this, Is, In the
early morning to build u number of
smdN fires along lust outside the cor
raj, on the windward side of the flock;
on each of which fires n handful OF to-
hacco stems should be placed and the
flock slowly moved to and through
the smoke, 40 that each sheep gets
we'll smoked This smoking process
should be repeated for two or three
consecutive mornings.
I The flock should be closely watched,
and those members that resist the
smoke treatment, should be separated
from their fellows, driven into II small
corral, and each In turn be treated by
having calomel, mixed with som,
bland oil, In the proportion of on,
ounce of calomel TO halfpint of oil
of which one or two tablespoonful,
should be poured into each nostril, tn,
sheep being SO held that his nos,
points upward, aud retained in thi,
, position one or two minutes after Tia,
medicine is introduced. In case
where the affected animals are com
paratively valuable, aud the tloclinas
ter Is willing TO take the trouble to Il,
: so, he can spray the nostrils for five %
g ten minutes once II day, with warn
! aqueous solution of corrosive subj
9 mate, one grain to two ounces of wa
Y ter, and blow dry calomcl through
quill into each nostril.
