4. Roaches Facts
Question:
Do cockroaches have
significance as well?

5. Significance:
Ecological Significance
- Paige ( 1998) cited that cockroaches play
a vital role in recycling of nutrients.
- Involve in pollination and a part of the
food chain.
- Medical Significance- Historical
accounts claimed that these insects are
used to treat Asthma , Stroke , and
Bronchitis , and Urinary Retention.

6. II. Characteristics of the Family Blattidae
Oval and flattened body shape;
Thorax covered by a large plate (the
pronotum), which extends partly over the
head;
Chewing (mandibulate) mouthparts;
Compound eyes and 2 simple ocelli-like
spots;

7. 2 pairs of membranous wings when present.
Forewings are more sclerotised than hind
wings. Wings are folded left over right
when at rest;
Prominent cerci;
Long antennae;

8. IIA. Life Cycle
Have incomplete metamorphosis;
Lay eggs in an OOTHECA ( egg case);
Egg stage lasts from a few weeks to a few
months;
The young resembles the adults but usually
lighter in color and lacks wings.
Nymphal Instars- young cockroaches
1-12 months span of time until they reach
maturity depending on the type of species.

9. Life Cycle of Cockroach

10. IIB. Feeding Habits
Majority are omnivorous
Some feed on rotting wood ;
Some harbor symbiotic gut protozoa that
aids in cellulose digestion;
Most domestic species eat almost
everything.

11. IIB. Habitat
Can thrive in both wet and dry
environments;
Most species are nocturnal and ground
dwelling usually hiding during the day in
crevices , bark and logs , rocks and
burrows;
Some occur in plants or on litter;
Some are associated in human habitation.

12. III. Common Species found in the
Philippines
American cockroach (Periplaneta
americana)

13. Appearance: American cockroaches
are reddish brown with a yellowish
figure 8 pattern on the back of their
head.
Region: This species is located
throughout United States , Asia and
Europe.

14. Habitat:American cockroaches are often
found in sewers and basements, particularly
around pipes and drains.
Unique Facts: The American cockroach is
the largest of the house-infesting
cockroaches. They are active when the
temperature is 70 degrees or higher, but
they can survive lower temperatures with
the right conditions.

15. Brown banded Cockroach (Periplaneta
brunnea)

16. Appearance: Brown banded cockroaches
are brown with pronounced banding across
their wings.
Region: This species is found in the US and
Asia and throughout the Philippines.


17. Habitat:
Within a room, brownbanded cockroaches
tend to prefer warmer, drier, and higher
locations than any of the other urban pest
roaches. They are often found in upper
cabinets or in rooms other than the kitchens
or bathrooms. This species often hides its
egg cases in or under furniture.

18. Unique Facts: Brown-banded cockroaches
get their name from the two lighter bands
they have across their dark brownish
bodies. The male’s wings are larger than the
female’s wings.

19. Oriental cockroach (Blatta orientalis)

20. Appearance: Oriental Cockroaches are large
very dark colored and shiny.
Region: This species is found in the
northern region of the United States ,
Southeast and South Asia and other parts of
Europe.

21. Habitat:
Oriental cockroaches are often found in
sewers and will enter structures through
drains. They find indoor harborage in
basements and crawl spaces. They can also
be found in leaf piles and firewood
outdoors.

22. Unique Facts: Oriental cockroaches are
sometimes called "water bugs" because they
come out of drains, and "black beetle
cockroaches" because of their smooth, dark
bodies. This species creates a strong smell
and is considered one of the dirtiest of all
the cockroaches.

23. IV. Other Species Found in other
countries
Smokybrown cockroach (Periplaneta
fuliginosa)
Florida woods cockroach (Eurycotis
floridana)
Common shining cockroach (Drymaplaneta
communis)
Botany Bay Cockroach (Polyzosteria
limbata)


24. Perisphaerus sp. from Malaysia with well
developed young, which have recently left
the underside of the mother.

25. Female epilamprine cockroach from
India carrying young.

27. V. New Species
Jumping cockroach
Scientificclassification
Kingdom:Animalia
Phylum:Arthropoda
Class:Insecta
Order:Blattodea
Family:Blattidae/ Blattella
Genus:Saltoblattella
Species: S. montistabularis

28. Saltoblattella montistabularis —
saltoblattella is Latin for "jumping
cockroach" and montistabularis refers to
Table Mountain — is a delicate creature just
a centimeter (less than a third of an inch)
long with powerful hind legs and bulging
eyes. It could endear itself even to those
who recoil at the thought of a household
cockroach.

Cockroaches

31. VI. Evolution
This new species of cockroach exhibits
unusual morphology. It has legs that are
highly modified for jumping. Prior to its
discovery jumping cockroaches were only
known from the Late Jurassic. This extant
cockroach has jumping ability that is on par
with grasshoppers.

32. In addition to the leg modifications, it has
hemispherical shaped eyes that protrude
from the sides of the head instead of kidney
shaped and the antennae have an additional
fixation point to help stabilize them during
jumping.

35. HOW TO IDENTIFY A
COCKROACH
Count the six legs of the specimen - a cockroach has 6 legs. Count the six legs of the specimen - a cockroach has 6 legs. 

40. Look at the brown or black color of the cockroach. German cockroaches and
 American cockroaches both have a reddish brown color.Oriental cockroaches have 
a black,shiny color. Brown banded cockroaches and a smoky brown cockroach, on 
the other hand , have a very dark brown color.
