Following is brief article on the
species of mosquitoes occurring on
the Eastern Shore, and relative i'm
portance as far as known and the
necessity for the survey which has
been made. This has been prepared
by DR.. Donald McCreary.
by most of the inhabitants of the
Eastern Shore mosquitoes are divid-
ed into two classes, the ones that
bite and the ones that do not. Peo-
pie who are annoyed and made mis-
cradle by this pest are not primarily
concerned with the species that is
causing the discomfort. Their sole
hope is that whatever mosquito it is
will cease its attack.
1.-THE Entomologist, however, is of
necessity interested in the various
kinds of mosquitoes that inhabit this
section of the country. Inasmuch as
investigators in New Jersey have
studied the mosquito
problem of that state their findings
can be used for predicting, approXi-
mately, what mosquitoes will be
found on the Del-Mar-Va Peninsula.
In all, probably a dozen species of
economic Importance occur here.
These may be divided into several
more or less we'll defined groups.
THE first group to be considered |
ire the salt marsh mosquitoes. There
ire several species in this group that |
,ause intense discomfort both along |
he seashOre and many miles inland. |
They breed in untold numbers in the |
ialt meadows and, in fact, in almost |
INV situation where brackish water |
S found Numerous generations each |
vear combined with the ability to fly !
ong distances make this a highly
important group.
"The swamp mosquito group is
of two important species
md certain others that are only oc-
asionally present in sufficient num-
,ers to cause annoyance. The drain
ng of fresh water swamps is the
,est known method of eliminating
he mosquitoes comprising this
roup.
1.-THE woodland pool mosquitoes
re not especially troublesome to
IAN except when he builds habita-
ions near their breeding places. The
pecies of this group, with a single
have only one generation
ach year. Oiling the breeding place
ill ordinarily give relief from their
tack. The one species with sew ]
raj generations would necessitate, !
owever, a different control meas !
re.
1.-THE malarial group includes s
lree species which are troublesome ii
New Jersey. Undoubtedly the t
lme will hold true for the Del-Mar- S
a Peninsula. Inasmuch as their |
ght range is but slightly over I
lie, they present a more or less G
cal problem. Brackish and unpol-
ted water furnish the breeding =
nditions necessary for the devel- r
Dment of these species. Il
"The house mosquito group con- '
flutes a problem localized in char n
ter. They breed in rain barrels, a
ater filled cans and practically any v
anding water near human habita- d
