00:26Public Enemy Number One
00:28Anopheles, the malaria mosquito
00:32Wanted for willful spreading of disease
00:35And theft of working hours
00:37For bringing sickness and misery
00:39To untold millions in many parts of the world
00:45This tiny criminal is linked to the destinies of man
00:48In a cycle of disease transmission
00:51That could not exist without either man or mosquito
00:53Each is solely dependent on the other
00:56For the existence of the dread malaria
01:00Anopheles is readily distinguished from other mosquitoes
01:03By the fact that she stands on her head
01:05At an angle of 45 degrees or more
01:09This newly hatched female has not yet touched human blood
01:13Therefore does not contain malaria
01:16But if we follow her
01:17We'll soon learn how she becomes a malaria carrier
01:21Like all thieves and killers
01:23She works best under cover of darkness
01:28Locking and barring doors and windows
01:31Will not keep this hungry prowler out
01:33She can enter through a small crack
01:39What will she find to steal here?
01:42Only a little blood
01:43Which this man, wracked with the chills and fever of malaria
01:47Will never miss
01:51Assuming her typical angle of 45 degrees or more
01:55She injects saliva to make penetration easier
01:58And in a few seconds she begins to feed
02:02But this man is sick
02:04Along with his blood
02:05She's drinking in the parasites
02:07Which cause malaria
02:11Gorged with disease-laden blood
02:13She makes her way to some cool, dark place
02:15Where she will rest for several days
02:18And digest the blood
02:19Although the blood is digested
02:22The disease parasites are not harmed in any way
02:25On the contrary, they multiply to great numbers
02:29Hungry again, she flies out
02:32As evening falls in search of blood
02:34This time she carries with her
02:36The malaria parasites with which she is infected
02:45Enjoying the peace and plenty of the home
02:47He's worked so hard to build
02:49This man is healthy and happy
02:51Little does he suspect he's to be the victim
02:54Of this bloodthirsty vampire
02:57Again, saliva is injected to make penetration easy
03:01But this time the saliva contains malaria parasites
03:04Which enter the bloodstream
03:06She dines on healthy blood
03:08And in payment leaves the chills and fever of malaria
03:14In all probability, this man will not die
03:17But neither will he truly be alive
03:20For he'll be continually in poor health
03:23Unable to work and keep up his farm
03:27Slowly he will lose all he has worked for
03:30His crops will rot in the fields
03:32His buildings and fences fall into disrepair
03:36His livestock will be neglected
03:38And he'll be unable to earn the money to feed and clothe his family
03:43Multiply this man's tragedy by numberless cases all over the world
03:48And we have millions of dollars lost
03:50As well as untold misery for the victims
03:53And all because of this tiny criminal
03:56Which has assumed the proportions of a monster
04:02Are there six or seven people in the audience
04:04Who will volunteer to help us combat this evil?
04:10Good
04:11Well, thank you, men
04:13But before we can attack the enemy
04:15There are certain facts we must know
04:17The first and all-important fact is this
04:20The Anopheles mosquito must have water to lay her eggs in
04:27These eggs float about and soon hatch
04:30Into larvae or wigglers
04:32Which lie parallel to the surface where they feed and breathe
04:37In this larva stage, the mosquito is easy to control
04:41After seven to ten days, the larva becomes a pupa or tumbler
04:46And can still be controlled
04:48But once she emerges from the pupa as an adult
04:51She can slip through our fingers and become a menace to human life
04:55Within a mile of her birthplace
04:58All right, men
04:59Now we can begin to fight
05:08We can start by cutting the weeds where the mosquito lays her eggs
05:20This makes it easy for the fish to get in and eat the wigglers
05:27Spraying oil on the water is a sure way of killing mosquito larvae of all kinds
05:32The oil enters the breathing tube and promptly kills the wiggler
05:42Those are wigglers, dopey
05:44Give them the oil treatment
05:47That'll kill them
05:51Dusting with Paris green is an effective way of killing wigglers
05:55And is economical for covering large areas of water
05:58A thin film of Paris green is strong enough to kill the wigglers without poisoning the fish
06:07Mosquitoes must have water to breed in
06:12These pools will always be a menace to our health
06:15Unless we drain the water away
06:20There's one way of doing it
06:23Even this hollow stump can harbor mosquito larva
06:33Say, that looks like smoke
06:35Let's go in and see
06:37Attaboy, dopey
06:38Spray all the dark corners and under things
06:41You'll find mosquitoes where you least expect them
06:51Yes, we've got to kill everyone in the house
07:07The permanent way to get rid of breeding places is to fill them with dirt
07:15If you want to keep the rain barrel free from wigglers
07:17Let's put a screen over it
07:21By covering the cracks in the walls with building paper
07:24We can keep mosquitoes out
07:39Anything that holds water for a few days
07:41Is a likely breeding place for mosquitoes
07:44And we can't afford to take any chances
07:47So we're going to bury these cans
08:00To be safe from malaria
08:02We must put screens over all the doors and windows
08:05Screens can save you a lot of misery
08:11Attaboy, dopey
08:13Killer good and dead
08:22To avoid being bitten by anomalies
08:24We must put netting over the beds
08:26Then we can sleep in safety
08:29Don't let her get away
08:30She's a killer
08:39Yes, even the small cracks in the floor must be sealed
08:55And so we leave them to enjoy their well-earned rest
08:59Free from the annoyance of mosquitoes
09:01Safe from the dread malaria
09:05Contrast their peace and happiness
09:07With the misery and sorrow of this unfortunate plague-ridden family
09:12These people have lost everything
09:15Simply because they failed to take a few easy precautions
09:19Remember, there is only one cause of malaria
09:22The mosquito
09:24Destroy the mosquito and you will wipe out the disease
09:27Then in place of sickness and poverty
09:30There will be health, safety and happiness
