PARIS GREEN TO
CONTROL MALARIA
MOSQUITO BREEDING

Suggestions for the use of Paris
green as preventive of the multi
piicatiOn of mosquitoes, of the genus
Anopheles which carries malaria, is
one of the new features to be found
in Farmers Bulletin 157O-F, MO
squitO Remedies and Preventatives,"
, JUL published for free distribution
W the united States Department of
Agriculture. This bulletin by DR.. L.
o. Howard and F. c. BishOpp of the
Bureau of Entomology is revision
OF and superseues an earlier bulle-
tin, No. 444-F, by Doctor Howard,
ana brings up to daCe the best in
formation available for the preven-
ton of the breeding of these pests.
1t also contains many suggestions
for the exclusion of mosquitoes
from homes and dwelling places, as
well as remedies and renet meas
ures after the insects have made
Lheir attacks successful.
Paris green mixed with fine dust
in the proportion of one part to nine
by weight may be blown as a pow
der over the surface of bodies of
water and will kill such mosquito
larvae as feed at the surface of the !
water On large areas airplane dust
ing has proved effective. At Guam /
ticO, Va, last year the material for
busting a considerable area OF salt |
marsh cost Y cents an acre, and |
gave an effective control. On small /
ponds hand dust gun may be used.
Petroleum oils with or without
the addition of various other sub
and drainage of breeding
places, continue to be the main
reliance for control of mosquitoes.
Spirits of camphor or pine oil rub
bed on the face and hands are SER
viceable in keeping mosquitoes
away for a time, as is oil of penny
royal, but none of these will last
through the night. Oil of citronella
alone or in combination is favored
repellant. The authors particularly
recommend a mixture of one ounce
each of oil of citronella and spirits
Of camphOr and a half-Ounce of oil
Of cedar. Ordinarily, they say, a
few drops on a bath towel hung over
he head of the bed will keep away
he common house mosquitoes for
several hours, or if they are abund-
INT and persistent, the mixture may
)e rubbed on the face and hands.
The yellow fever mosquito bites at :
laybreak after the effect of these !
epellents is likely to have worn /;
If. A mixture of an ounce of oil of =.
itronela with four ounces of liquid
retards the evaporation
f the citronella and makes it eff
ective for a longer period.
The bulletin includes suggestions
or screening homes and breeding Z
laces, for inspections of mosquito
reeding places, such as discarded
ms and bottles and low points in
utters where water stands, the use
t smudges and fumes for the killing
f mosquitoes in houses and rooms,
nd the use of sprays, most of which
re kerosene extracts of pyrethrum.
The most satisfactory remedy for :
ne itching sensation following mo-
quito bites known to the writer's 3
rom their personal experience, =
ley say, has been moist soap. Wet =
ne end of piece of ordinary toilet )
pap and rub it gently ON the pune 2
Ire, and the irritation will soon 3
ass away. Others have recommend 2
1 household ammonia, or alcohol, 4
r glycerin. One correspondent !
larks the puncture with a lump of Z
ldigO; another with napthaline (
10th balls; another with iodine"
The greater part of the bulletin :
calls with abolition of breeding z
laces, large and small, and with Z
ethOds for destroying mosquitoes.
he authors emphasize that mosqui- Z
'es are not merely nuisances, but !
re also conveyors of serious dis z
