scale which is infesting many trees IN

| he got samples of the scale taken from
Kenosha naples and sent them to the
| Department of Entomology in Wash

sistant Of the Bureau of Entomology
/ has made the following statement in
regard to the scale and the best RENE

of the pest:
Gin dealing with an infestation by
the cottony maple scale, the most I'M
portant matter to be considered in each
case is the advisability of artificial
means of control under the existing
conditions. The natural enemies Of
| this pest have done and are still do
| ing such effective work in it's control,
that it is a question whether remedies
/ should be applied when the infestation
| is not serious. Nature always main
tains balance, and this pest can not
be in the ascendency for any great
length of time. On the contrary, it's
parasites will eventually multiply so
rapidly as to completely check its pro-
gress, and it may even narrowly es
| cape determination.
Insecticides applied for a pest al
ways kill its parasites and oftentimes
predaceous enemies are also destroyed.

binotata were found to have been de-
stroyed by summer treatment with
kerosene emulsion for the cottony ma
pie scale in parks of Chicago, and no
doubt thousands Of the minute chal-
cids were killed, as they were found
quite plentifully on unsprayed trees.
If it. is necessary to resort to arti-
fetal means of control, as seems to be
the case in some sections, the spraying
should be delayed until fall or winter,
when the Hyperaspis is alternating at
the bases of the trees among lichens,
moss, or dried grass. Care should be
exercised in the use of spray, and the
bases of trees should be covered with
canvas or other suitable material to
prevent the spray from running down
the tree-trunks and collecting at their
bases.
When the trees have become dor
mant, after the falling of the leaves,
they can be trimmed and thoroughly
sprayed with a strong kerosene emul
sion, which will kill every scale reach
ed by the spray, without injury to the
trees. Scarcely onefourth the guam
tity of emulsion is required to spray
| a tree in winter condition that is neces-
sary when tree is covered with dense
foliage and both sides Of the leaves
must be reached with the spray. Some
| excellent results have been obtained
| by S. Arthur Johnson in experiments
against this pest in Denver, COL He
found that kerosense emulsion 25 per
/ cent or more in strength or whale-on
soap at the rate Of pound to l gal
lon Of water was very effective, ap
parently killing all scales which re-
ceived the spray.
Kerosene emulsion of not more than
10 to IL per cent of oil can be thor
oughly applied with safety to maple
trees, but the tips and margins of the
leaves may be injured even at this
1 strength. Box-e1der will be almost de-
foliated with IL to Is per cent solu-
ton. Less than 10 per cent emulsion
will be of little value against the
young unless they have recently hatch
/ ed. Since the Matching period may ex-
| tend over six or eight weeks, it will be
seen that more than one spraying will
be necessary to insure success, and.
coupled with the fact that it is very
difficult and disagreeable task to thor
| oughly spray tree in foliage, the win
ter treatment will be found more sat
isfactory in every way. And at that
season the larvae of predaceous BEETLES
would not be destroyed

by pouring the mixture into the tank

which must be diluted before using.
