STOCK RANGE AND DAIRY.
From THE HAWAIIAN of to-day. |

OF the gives promise OF
Horn Fly. becoming a seri-
Gus menace to
stock interests here, made its ap-
pearance in force on the Hawaiian
Islands about three months ago.
Professor koebele, the Government
EntomologiSt, a man whose great
service to the horticultural interests
of California entities his judgment
on insect pests to great weight, has
kindly furnished THE HAWAIIAN with
some interesting points on this new
stock enemy. Because of the COM
paratively short Summer season in
the United States, the horn fly there
does no great damage, although it
annOyS the cattle to such an extent
that there is a noticeable loss of flesh
and decrease in the amount of milk.
The horn fly is black, and a little
smaller than the horse fly. 1t gets
its name from its habit of rooSting
on the horns, where it can take a
nap without being easily diSlodged.
1t annoyS the cattle by biting them,
anywhere and everywhere, night
and day. The Agricultural Depart
ment of the United States has rec
commended the use of a kerosene
emulsion spray to fight this pest.
The emulsion is composed of one
part milk and two parts kerosene;
the spray is one part emulsion and
three parts water. This remedy
has been tried here, without any
results, however. Professor kOebele
believes the most ehectual thing to
do would be to fight the larva; but
this will shortly be shown to be a big
undertaking, in some cases. The
breeding place of the horn fly is in
the COW manure, and each dropping,
if undiSturbed, is sure to produce an
untold number of the pests; and be-
cause of our all-the-year climate,
the Professor believes the fly will
breed mere with little or no Interrupt
ton. There are many predaciouS
insects of various kinds in the
United States which, in cases of this
kind, would eat the larva: here
there are no such enemies of ene-
mics, and pests like the horn fly
must be fought with improved meth
DDS. In the States, in fighting the
horn fly, it is recommended that
shovelful of lime be put on each
dropping; that would be effective
here, no doubt, but is entirely i'm
practicable for this country, because
many tons of lime would be required
every day. And how could this
remedy be applied on some of the
island ranges, embracing many
of acres, on which are
many thousands of cattle An
equally effectual way, probably,
would be to spread the manure, so
that the breeding places of the flies
would be destroyed; but even this
method, on big ranges, would in
vOlVe an immense amount of labor.
On small stock or dairy farms the
pest may be fought easily by any
of the methods suggested, except,
perhaps, the spray; and in town
yards the manure may be buried,
md so leave no opportunity for the
lies to perpetuate their kind.
Our fine climate and rich soil are
lgainSt us in some cases, because,
IS the rain falls on the just and the
Unjust alike, so good and evil things
hriVe equally well. THE HAWAIIAN
will hasten to give its readers any ;
Information obtainable in relation to
he horn fly or any other stock pests,
nd the most likely means of getting
id of them. Correspondence, for
publication, is invited from stock
