Tells of Skeeter
Control Work
A lot of Los Banos people this week
have a much keener appreciation for the work the Merced County Mosquito Abatement
District is doing to eliminate disease-bearing and pest mosquitoes throughout
the county, thanks to the efforts of the district’s entomologist, Edgar
A. Smith, who in the last week has spoken before several local service group luncheons
and at the two local schools.
Speaking at the Rotary Club luncheon Tuesday
noon, Smith emphasized the enormous amount of control work necessary in this,
the largest mosquito control district in the state. Because most of our mosquitoes
come from irrigated pasture and swamp land and poorly drained alfalfa fields,
Smith stated frankly that full control can never be accomplished without the complete
cooperation and aid of the farmers, who can easily eliminate mosquito breeding
areas by improved irrigation methods and installation of simple drainage ditches
which will not only eliminate the mosquitoes but be profitable from standpoint
of better crop production.
Water, Smith emphasized, is the one all-important
item around which all mosquito control centers, because water is absolutely necessary
for completion of the mosquito’s life cycle. In this connection, Smith discounted
the popular belief that mosquitoes hatch and develop in hedges, lawns, shrubbery,
etc. this erroneous impression is prompted by the fact that the mosquitoes, on
reaching adult stage, find excellent protection from the sun in the shade of the
foliage.
Smith said his office has to date identified 19 different kinds
of mosquitoes in this county, of which the two most numerous species are the dreaded
carriers of malaria and sleeping sickness. Each specie has its own peculiarities,
feeding and breeding habits, but all have the common four-stage life cycle: egg,
wiggler, pupa or tumbler, and full grown winged mosquitoes.
As to the
size of the job here in the county, Smith said that last year the district maintained
control over some 80,000 acres of permanent pasture, plus some 800,000 acres of
unirrigated pasture land. As an example of the rapid rate of reproduction, Smith
stated that with only 100 eggs deposited on an acre of neglected pasture land
last fall, 5,000 mosquitoes would be developed within two weeks after the first
spring irrigation, and their descendants, in less than two months, would number
well over 625 million – enough to give everybody in the county a definitely
bad time.
Commenting on the importance of proper irrigation, the speaker
cited one 1,000-acre field of permanent pasture near Merced which in previous
years was possibly the county’s most prolific mosquito source. Today, the
owners have constructed a drainage system to carry off surplus water and one man,
with a small jeep spray outfit, can now maintain control over the entire area.
L. J. Spindt, local school principal and member of the Abatement District
board of directors, also spoke briefly at the luncheon, explaining the operations
of the district, and outlining the proposed budget for the coming year. Spindt
said that during the district’s initial year they received much low-cost
and free spray materials from government surplus and also received considerable
state aid, which will not be forthcoming next year. To properly do the job to
obtain satisfactory control. Spindt said it will be necessary for the county supervisors
to authorize an additional tax appropriation. Numerous members of the club voiced
favorable expressions as to a proposed tax increase for this purpose, and praised
the work that has been done thus far.
Following the talks Smith showed
an educational Walt Disney cartoon prepared especially for the U.S. Army, showing
the Seven Dwarfs doing mosquito control work, together with scenes showing life
history of mosquitoes and areas in which they abound. The film is being shown
at all schools in the county as well as before civic and service groups. Any group
wishing the film for their program is asked to contact Smith or the district manager,
Wesley Ewing, at Merced.
