Simple .Nethoa Of Destroying the Hessian FLY
As the wheat crop tins season has in some places, suf-
tered considerable damage from the destructive ef,
tects of this insect, we are happy TO be enabled by @
valuable and oblioing correspondent, TO publish the
following direot:ons- for destroying it.
The Hesslan lily deposits itseggso on the wheat ear tes
foe 1t IS reaped: the egg is so small as to he invisible
TO the naked eye. hut may be seen very distinctly with
a microscope; sometimes one grain of wheat will be
observed to have several ofthese eggs on it. They
are attached 10 the wheat by a glutnous substancs
deposited around them, by the parent fy. by which
they are held so firmly on the surface as not 10 be eax
shy removed by the molten OF Gaping, thrasliBg, SC.
Shortly after the seed begins to terminate in the soil.
the genial heat OF the season brings the Young fv
from Its egg, III the form OF Il Very small maruot fss 10
the case with all insects; these little maggots deposit
themselves at the root OF the stalk, to The seed of which
their eggs had been attached; bot ween the stem and
the lowest blade or leaf, where they NAV be discov-
cred, during the month of May and beginning of June
quietly reposing; here they remain until the warmth
OF the season brings them TO maturity, when they
commence eating the substance 10 which they have
been attached. 1t is not until this period that their
destructive effects are visible, by iha wheat becom~
ing withered and %blighted. This accounts for the fact
That wheat, which is attacked by this destructive in
sect, presents q healthy appearance until the month
OF June, the period at which this embryo by begins
to use food,
Now i'll is evident that ifthe eggs of this fly can be
destroyed on the seed wheat, by any process that will
not also destroy the vcgctative quality of the grain.
Tho rninous effects will be avoided. This can be done
BY the following very simple process.
''Sobk the seed wheat IN water for twelve hours:
spread it out on the barn floor. so as to allow the su.
Perabundant water to escape, then take fresh Stacked
lime, and mkt t among the wheat in quantity sufficient
to have every grain covered with the lime, taking
care to stir the wheat well with a shovel, so that no
particle may escape coming in full contact with the
lime, which, wheli thus applied, will in a short
time destroy the eggs, and consequently preserve tha
grain from destruction
Our correspondent assures us that the egg, which
before the application Of the lime appears clear and
transparent, afterwards becomes opaque, and puts on
the appearance of an added egg. The efficacy of the
above remedy has been established by several expe-
riments' one of which we will here relate. Wheat. sun
posed to be infected with the Hesslan hy was taken,
one half of the quantity wes treated with lime, and
the other halfwas sown in the same soil with the pre-
pared seed, in alternate drills; the result was that eve
ry stalk from the prepared seed, came TO maturity and
was productive, whilst the alternate drills which had
been sown with upprepared seed were almost totally
DESTROYED.
The above remedy, for so serious an evil, cannot
be too widely circulated-wc would recommend its
translation into the French papers, and we think the
Cures ofthe country parishes would confer a benefit
OH their parishioners, by having it made known at
their respective Church doors, sitter divine service.
