control of rodents and innsects

2. FIVE BASIC METHODS OF
CONTROL
1. Physical(mechanical)- use of
mechanical devices or physical
forces.
2. Chemical- use of
rodenticides, insecticides, and
larvicides.

3. 3. Biological- consideration of
limiting factors that affect their
growth and reproduction.
4. Environmental- cleanliness of
the immediate premises and
proper building construction and
maintenance so as to prevent
access of these pests into human
dwellings

4. 5. Educational- health education and
information such that the population will
understand and appreciate the importance
of control measures and therefore motivate
them to change their habits, practices, and
attitudes, which promote the survival and
multiplication of pests.

7. Murine Typhus
 also called endemic typhus
is a form of typhus transmitted
by fleas, usually on rats
is an under-recognized entity, as it is
often confused with viral illnesses
most people who are infected do not
realize that they have been bitten by
fleas.

9. Rat bite fever
 is an acute, febrile human illness
 caused by bacteria transmitted
by rodents, rats or mice in most
cases, which is passed from
rodent to human via the
rodent's urine or mucous
secretions

11. Salmonellosis
is
an infection with Salmonella bacteria
most people infected
with Salmonella develop diarrhea, fev
er, vomiting, and abdominal
cramps 12 to 72 hours after infection

13. Weil’s disease
is the acute human form of a bacterial
infection with a raft of different names:
mud fever, swamp fever, haemorrhagic
jaundice, swineherd's disease, sewerman's
flu.
The infection is caught through contact
with infected animal urine (mainly from
rodents, cattle or pigs), generally in
contaminated water, and typically enters
the body through cuts or scrapes, or the

15. Rickettsialpox
 is an illness caused by bacteria of the Rickettsia genus
 the first symptom is a bump formed by the bite,
eventually resulting in a black, crusty scab
 is treated with doxycycline.
Doxycycline is a member of the tetracycline
antibiotics group, and is commonly used to treat a variety
of infections.

18. 1. Preventive
(environmental control)
a.Elimination of food by
proper garbage
disposal and food
storage.

19. b. Elimination of
breeding placesa
(harborage) by proper
refuse storage,
satisfactory house-
keeping and proper
design and construction

20. c. Rat-proofing of
buildings-Special
construction to prevent
rats from going under,
through, and over the
building.

21. d. Health education
and information

22. 2. Suppressive
Measures
a. Physical- use of
traps(spring trap, cage
trap, etc.), shooting with
bullets, darts, catching,
clubbing

23. b. Chemical- use of poisons
which maybe generally
classified into:
b.1. contact poisons
b.2. stomach poisons
b.3. fumigants
b.4. sterilants

24. c. Biological- use
of living rat
predator and
disease agents

26. Mosquitoes are slender delicate insects having scales on their wings
and long antennae. The mouth parts are adapted for piercing and
sucking, but the males do not suck blood, the boring apparatus not
being strong enough to penetrate the human or animal skin. The
female mosquitoes feed only on the blood of man and animal, while
the male mosquitoes feed on the nectar from flowers

27.  Anopheles Minimus Flavirostris is by far the most dangerous malaria
transmitter in the Philippines. Anopheles mangyanus seems an
effective vector among the primitive Mangyans in Mindoro island.
 The control of this mosquitoes is being undertaken by the Malaria
Eradication Program under the Department of Health so as to
achieve the eradication of malaria in the Philippines and to prevent
it’s re-introduction.

28. The vectors of these diseases are
found in the Philippines are Aedes
poecilus and Culex quinquefasciatus
The control of these mosquitoes is
now being undertajen by the
Filariasis Program under the
Department of Health.

29.  Aedes Aegypti is the carrier of dengue and yellow fever. The adult
mosquito is medium-sized and gives the impression of being gray,
but when closely examined, the gray color is found to be due to
silvery working on the legs, abdomen and thorax.
 To control mosquitoes for disease prevention, mention has been
made of the Malaria Eradication Program and the Filariasis
