Introduction to Flies
What is Fly?1-
True flies are insects of
the order Diptera
2-The name being derived
from the Greek di = two,
and ptera = wings
3-Insects of this order use only a
single pair of wings to fly, the
hind wings being reduced
to club-like balancing
organs known as halteres.
Differences Between Flies and Fleas
Fleas and flies both are in the phylum Anthropoida, class Insecta.
fleas and flies are distinctly different creatures with varied traits and habits
Fleas
Wingless insects
Order Siphonaptera
Hard and flattened body
Sucking mouthpart
Brownish in color, Though flightless but three sets of legs used to jump
Jump distance as long as 16 inch horizontally
Cont..
Flies
Winged insects
Order Diptera which means "two wings."
There are 16,000 varieties of flies in North America alone.
Colors and sizes ranging from 0.06 to three inches in length.
All are distinguished by a pair of functional forewings and a reduced,
second pair of hind wings called halteres.
The halteres are leg-like in appearance, used for stabilization, equilibrium
or airspeed detection
How Flies Transmit Diseases
Flies transmit diseases in two ways:
First one through feces; Feces contaminate the food in this way
pathogen enter in the body through feed
2nd one through bite. Bite break skin
Pathogen transfer to blood

Some Other Diseases By Flies
Flies can also carry infectious diseases by transporting infection causing
agents, i.e. bacteria, on their feet or in their mouth after they feed on
something that’s infected
Flies are believed to be responsible for spreading diseases such as:
cholera
typhoid
trachoma
salmonellosis
strep infection
staph infection
Some Other Diseases By Flies Cutaneous myiasis is an infection that is caused by skin infestation of fly
larvae It’s spread to our skin by some type of blood sucking insect And it doesn’t have be a fly making the deposit In addition, a fly’s saliva can trigger an allergic reaction or anaphylaxis
