Gan Island Post

Control of mosquitoes is achieved by two
a. Prevention of breeding.
b. Use of insecticides against larvae, pupae and adults.
The most common breeding sites found on Gan are: Tins,
Bottles, open surface drains, fire buckets, discarded
buckets, basins, large tins, old tyres, coconut husks,
static puddles, WC's and cisterns.
Prevention of breeding in the first seven is a relatively
simple matter. The old Indian Army had a day designated
as a dry day once a week. On this day personnel of
all sections would scour the surrounds of their buildings
and any discarded articles capable of holding even
small quantities of water were collected and placed
Articles such as fire buckets were emptied, cleaned
and refilled. The repetition of this practice every
effectively breaks the ten-day cycle necessary for
development from egg to adult. Any Section found to
harbouring breeding sites within their surrounds were
in for a severe rocket. - GAN???
Defective plumbing of any type should, of course,
be reported on form 5653. The use of larvicide's and
insecticides is restricted to trained personnel. All
buildings on camp are sprayed periodically with residual
insecticides. All female mosquitoes rest either before
or after taking a blood meal and it is during these
that she will absorb a lethal dose of insecticide.
If you have just been bitten by a type that rests
it may afford some small measure of consolation to
know that the bastard is going to die anyhow!
The swing-fogging that is carried out almost daily
in the domestic area is aimed at a quick knock-down
and has no residual properties. Incidentally, although
it may not taste very nice when you are in the middle
your breakfast, the insecticide used in the swing-fog
is harmless to man.
As can be expected on an island only five feet above
sea level and with an annual rainfall somewhere in
region of one hundred inches, large areas of Gan do
remain water-logged for long periods following prolonged
rain. These areas are treated with larvicide's and
waste oil, which, since it is not water miscible,
larvae by sealing them off from oxygen.
Well, that's it, and the next time the BBC Forces
Chance quiz team come to Gan you can tell them quite
authoritatively that mosquitoes do not sting
