MOSQUITOES

DR.. q. W. Drake, resident physician
at the Monteagle Assembly, writing to
thf Nashville Banner has the following
interesting artI Gle on this timely sub
ieot:
i'CuieX is the ordinary house mos.
quito. They are the most numerous
and widely distributed. They have no
stripes on their legs, wings or bOuy.
Their bodies are clumsy, and when at
Test on the wall their feet cieave to
it, their bodies being parallel to the
surface OF the wall. They sleep In
the daytime and bite at night.
Stegomyla presents some resem blance
to culex. It's form and position when
resting on the wall are like those of
culex, but it is striped and is we'll
known as the brIndled or tiger mos.
quito. StegomyIa often bites during
the day and is very voracIous. The
bire of stegomyia conveys the lnfec-
tion OF yellow fever. Stegomyla will
not live longer than five Gays if de-
prived of water. but will live for five
months OF more IL water is accessible.
Culex and stegomyia are the kinds
of mosquito most frequently seen and
heard. They sit on the walls during
the day and the hum of their wings is
often heard as they hover over us,
from time to time, seeking an oppor
tunIty to bite. In those respects they
differ from the anopheles which are
most direct In their methods give
little warning and bite in the dark.
The anopheles is the kind of mosQui-
TO that conveys the malarial parasite to
man. Its body is straight and of more
elegant form than that of culex or
stegOmyN, and its wings are spotted.
1t has long and thick proboscls, well
both for sucking the blood OF
its victim and injecting the infection
of malaria. When resting on surface
the body, unlike that of culex, which |
Is nearly parallel with the surface,
projects away from 1t at an angle, with
the head nearest ana the end of the
tail furthest away from it. IN adolf |!
ton to other characteristics the differ
ence in posture when seated on a sur
face aids in distinguishing the anophe-
les from culeX and sJegomyia, whose
pastures are similar. To sum up the
Inference in appearance between the
three kinds of mosqultO: Culex is
devoid t stripes, ..stegomyla has stripes,
DT bars, around Its body, aud anophe
les has dappled WINGS.
Now. as 70 the prevention of yellc W
fever and malariaI fever. Prevent the
bite of stegomyi ia ana you prevent the
Infection of yellow fever. Prevent the
bite OF anopheles and you prevent the
infection Of malaria. To prevent the
bite of mosquitoes use nets and wire
;reens where. mosquitoes exist, and
mosquito bIlgades to ex-
terminate the species ny pouring kelo-
ene OIL on standing water. and by
ponds, pools and puddles of
water, which furnish breeding places
or the mosquito.
The eggs of the mosquito are deposited
N the surface of the water. From the
ggs are Matched the larvae (wriggiers)
no the larvae evolve into the winged
dult mosquitoes. The wiggle-tails +:
onnd in vessels Of stagnant water are
be larvae Ct mosquitoes.
Every case of malaria IS the effect of {
1alsral parasites 10 the blood caused {
y the bite of the infected anopheies,
nd every case of yellow fever is pro- I
uced by the bite OF infected stegomyia. !
