INSECT PESTS.


sets Horticultural Society, Prof. C. H
Feinald, Phi. D., of the State Agricul,
tural College, read a paper on Injurious
Insects" from which the following ex-
tracts are taken:
CURCULIO AND SQUASH BUGS.
The plum eurculio has long been &
great annoyance TO fruit growers. If al
who cultivate plums would persistently
follow up the old remedy of jarnng tht
trees and destroying the beetles which
fall on the white cloth underneath, thi:
unanimity of action would reduce then
numbers and damage TO minimum; but
where shiftless, thTiftless, and worthless
neighbors allow them to multiply with
cut hindrance, it is impossible to sug
gest any efTectual remedy. Undoubted
" it VIII be Of great advantage to allow
chickens to run under the trees, for they
viii destroy many Of those that fall; but
Your negligent neighbors viii continue
20 furnish an ample supply. Some en-
tomOlogists are very sanguine that Pari:
green viii destroy the cnrculio if spray
ed on the plum trees as soon as the pet
ais fall 1t is reported that where al
ternate trees in the same row or orchard
have been sprayed, those treated witt
Paris green were not attacked, while
those not so protected were badly in
tested.
The common squash bug does not con.
sumo the surface of the leaf, but forces
its tubular mouth parts through the epi
dermis, and draws its food from the in
side of the Leaf, and is not affected by
poisons on the surface Pyrethum has
been found excellent. It may be used
as powder, and busted on by means OF
bellows, or in solution in water, which
is most economical and efficient. The
bulk of the powder is dissolved in the
water, to which it at once imparts its
insecticide principle. No stirring is nee
essary, but it should be applied in very
fine spray: the finer the more economic
al is its use. and the greater the chances
of its reaching all the insects II must
be used when first mixed. foi it allowed

LICE AID ROSE HCI>.

ticide for the cabbage butterfly, all kinds
of plant lice, flea beetless, thrips ON rose
bushes and grape-vines, and many other
insects, but it is liable to be adulterated
and one should be very careful to pur-
chase only that which is pure. 1t has
the great advantage Of being harmless
to man and the domestic animals, and
may be used with impunity when Paris
green or London purple would require
great caution. Half an ounce stirred in
two gallons of water was sufficiently
strong to kill any ordinary naked cater
pillar when showered on it, but was not
strong enough to kin the most hardy of
such as are protected by dense hairy
covering.
The rose beetle is a common pest and
feeds on so many different plants as to
make it much more troublesome than if
it confined its attacks to one plant alone
If they infest a plant on which it is safe
to use Paris green, this will be a most
effectuLl remedy; elsewhere pyrethrum
may be used.
To destroy currant worms and slugs
on rose bushes and pear trees and in
fact the Larvae of any saw flies, dissolve
an ounce of powdered helibore in lit
tie warm water and then dilute it with
two gallons Of water and spray on the
bushes. Paris green could be used in
spray on ornamental and shade trees for
any saw=f1y Larvae which might injure
them.
EMULSIONS,
Another very valuable insecticide is
the kerosene oil emulsion, made of two
parts of kerosene and one part of milk
either sweet or sour, but sour is prefer
able. Mix these in a pail or tub by con-
tinually pumping with force pump
through the spray nozzle back into the
pail In short time the liquids unite
and form q creamy emulsion, and final
y white and glistening butter. When
this mixture is required for use, take a
sufficient quantity, thin it by adding
some water, and when it is thoroughly
mixed add as much water as is necessa-
y to dilute it to the required amount.
For plant lice, a pint of the butter to a
gallon and half of water is fair pro-
portion. 1t should be applied with a
force pump and spray nozzle.
An emulsion NAV be made with soap
instead of milk by dissolving four pounds
If common bar soap in one gallon of hot
water, adding gallon of kerosene grad |
Tally while still boiling, and churning it |
With the force pump as before. A gel
ltinous compound is formed, which is
Tery stable and will keep long time if
protected from the air. 1t can then be
'educed by mixing with water, in any
but great care must be used
n making the emulsion to obtain COM
)lete union, otherwise the oil will injure
he foliage Of the plants.
