INSECT PESTS.
TIMEl.Y SUGGESTIONS LOOKING
TO THEIR EXTERMINATIGN.
The San Jose Scale and the Rene
dies-Other insccts-Select-
ing Nursery Stock.

Especially prepared by Matthew Cooke for the
RECoRI-UNIoN and WEEKLY UNIGN.i
That the San Jose scale insect infcsts
some orchards in this county is uniortu-
nately an established fact, and immediate
attention should be given TO prevent its
further spread Bartlett and other early
varieties of pear trees, peach and apricot
trees. etc, from which the crops of this
season have been gathered, should be at
tended to forthwith. At this season of the
wear there is generally Il brood Matching, or
to Give dates, between the middle of Au
gus; and middle Of September. The brood
Matched early in July have only a partial
protection or covering at the present time.
Therefore very effective worl, can be done
by thoroughly spraying the trees with Il
cheap solution any time within the next
few weeks, but the sooner done the better
will be the results obtained. If the last
brood of this species can be etfectually de
s.royed at this season of the year, it will
not be necessary to use the stronger soit-
tons in the winter and spring.
ORGANIZATION AND WORK.
In last weeks weekly issue and the daily
issue of the 9th instant, in an article on the
cottonv cushion scale, is mentioned the
organization of the citrus growers of san
Gabriel, Los Angeles county, formed to
prevent the spread of the pest named, and
the success resulting from their efforts.
Such organizations in the fruit districts of
this county. where the San Jose scale is
found, would well repay all concerned, by
uniting in 4 warfare iOr its determination.
,ar1 lao ~ q
frllit-gr0wcrs of This county for allowing
this pest 10 spread in their orchards; they
have the means at their disposal, and
should lose no time i'll combating the evil.
There Is no need of experiments; the prac-
teal work that has been done III other Sec
tons of the State. and the satisfactory re
suits obtained, are sufficient proof that the
pest can be eXterInindted from any district
by a united concert of action by all inter
ested. 1t must be remembered that the
washing or spraying of Il number of trees
that are infested IL an orchard, not Sutfi-
Gent or in other words is not To be con-
sidered thorough work; the pest may be
spread over other trees in the orchard and
yet escape detection, excepting that very
close inspection is made. Therefore every
tree should be treated, in order that the
work will be effective.
EFFEcTIvE REMEDIES.
For present use | would recommend a
solution, consisting OF coal oil, gallons :;
whale-oil soap or good homemade soft
soap, - pounds; water, IS gallons. Di
rections for preparation: In one gallon of
water boil one-half or tlrce-quartcTs of a
pound Of the soap. Then pour the boiling
water containing the soap into the coal oil
two gallons. Place this mixture in u YES
sci Tor barrel attached to Il force spraying
pump; then, by continuous pumping of
the mixture through nozzle into the YES
sci from which it is taken-say for ten or
twelve minutcs-it viii form Il cream. To
this add twenty-seven gallons of water in
which the soap is dissolved. and the solu-
ton is ready for application. Cost, about
81 cents per gallon.
If the trees are thoroughly sprayed with
this solution, it will destroy the young
scale and other insects infesting thc branch
es and foliage, and will not injure the
foliage The coal-0il mixture may be used
by adding the water without the soap, bat
it is not So effective in destroying insect
life
TEN-LINED LEAF EATER.
Mr. c.; The beetle which you send is the
ten-lineJ leaf eater; its scientific name is
Pollphp}'H dccemineoie. This beetle feeds
upon the leaves OF apple and other fruit trees,
and its larvae feeds upon the roots Of grass,
