College Entomologist Tells How to
subdue Different Varieties OF
Bugs and Worms.


Just what to use to kill the bugs
and worms which annoy the gardener
Of vegetable and small fruit tracts at
this time of year, is told in a new bull
letin Of the Oregon Agricultural Col
lege. which will soon be issued from
the college press.
PLANT lice, or aphids, such as the
cucumber aphis, cabbage aphis, let
tuce aphis. strawberry aphis rose
aphis and others, often become very
troublesome in the garden on various
plants, and some of them are very
hard to control" says III. r. Wilson,
entomologist. who is author OF the
work. BLACK Leaf, Black Leaf 40, or
kerosene emulsion, applied at any
time when the aphids become trouble
some, or before the leaves curl. is eff
fective.
For worms on cabbages and cauli-
flower Paris green or arsenate Of lead
should be used. For cut-worms on
onions, a bran-arsenic mash or
Paris green dry bait.
For the striped cucumber beetle.
the plants should be busted with Paris
green or sprayed with arsenate Of lead.
1t is well to plant some early squash
for trap plants, and when the beetles
are feeding on them, dust heavily with
Paris green.
Currant Lear Worms.
For worms on leaves of currant
bushes one should spray with arsenate
of lead. For fruit worms, destroy the
infested fruit. and allow the poultry
the run of the bushes when the infest-
ed fruit is falling. For aphis apply an
aphis spray (black leaf or emulsion)
when, the berries are just coming out.
Gooseberries should be given the same
treatment as currants
For plant lice ON hops, a thorough
spraying should be given with black
leaf or kerosene emulsion at the time
the lice are on the plant. and the
treatment may be repeated in June il
necessary. For aphis on peas the
treatment is the same
ITO get rid Of the striped cucumber
beetle on muskmelons the treatment is
the same as on cucumber vines, and
for flea-beetles on potato vines a
heavy strength spray of arsenate of
lead, whenever the beetles appear.
should be effective Watermelon
pests are treated as the muskmelons.
When there are cane maggots on
the raspberry bushes the only thing to
do is to cut out the infested canes and
burn them. For aphis and leaf hop
pers on rose bushes, kerosene emul-
sion or black leaf spray should be
used. For fiea-beetle on tomato plants
4 spray Of arsenate Of lead should be
used whenever they appear; for aphis
the kerosene or black Leaf spray IL
good.
Flea Beetles.
when flea beetles are found on
sugar beets, the plants should fbhf'
sprayed at once with arsenate OF lead
and the treatment should be repea -,
two or three times at intervals Of tx Q ..
weeks or so.
IF the beds OF violets have red
spiders or aphids, black leaf or kero-
,ene emulsion should be used. In case
one treats red spider with the kero-
,ene emulsion, the under side of the
eaf must be sprayed, to be effective.
"Carbolic acid emulsion is used to
lestroy the eggs and young maggots
which infest radishes. onions and sim
lar garden crops and occasionally for
,ther insects.
ITO make such an emulsion. dis
'olve pound of hard soap in gallon
II boiling water. add a pint of crude
'arbolic acid and churn (preferably
With a hand-pump) until the mixture
$ a creamy white. This forms a
Itock which may be diluted by adding
hirty times as much water as stock.
I should be applied to the surface OF
he ground about the plants"
