Introduction
Objective
Materials and Method
Result and discussion
Conclustion
Fly
Flies are insects of the order Diptera(containing an
estimated 240,000 species of mosquitoes, gnats, midges) .
They possess a pair of wings on the mesothorax and a pair of
halteres, derived from the hind wings, on the metathorax.
Compound eye
A compound eye may consist of thousands of individual
photoreceptor units or ommatidia . Compared with simple eyes,
compound eyes possess a very large view angle, and can detect fast
movement.
Color vision
Some insects are able to appeal with colors.
This requires two or more pigments, each of
which absorbs best at a different wavelength.
(Werner Backhaus,1990)
the remaining two respond best to ultraviolet
light (344 nm)
Introduction
Nowadays, in Thailand we can find fly in dirty
places such as either restaurant or your house.
What fly’s eye look like?
Fly’s eye is compound eye.[Roger Hardie,1988]
In market, If we observe sticky tape, we see it’s color
is green. We have known that spectral length appeal
to friefly and also dragonfly. Both of them have as
same compound eye as fly[S.L. Swihart,1969]. We
are interested what colors appeal to fly?
This project aims to investigate what colors appeal
to fly?
objective
Study about what the most color appeal to fly.
Meterials
Paper
Syrup
Aquarium
First we catch fly but we don’t made future board
in aquarium then we found that fly can escape
this.
Method
First you catch the flies.In plastic bag and impound
with rubber.
Build a box for impound fly.We divide this box in
two section. First for impound fly during we place
syrup.Secound we divide for place syrup.
Wait 30
secound.
Arrange paper
color.(24 times)
Then do it again.
Then put the flies in to the
aquarium(flies living part) by put a lid
up
Then we count a number
of fly on paper
And we do t-test ,
f-test.
Result
The color of paper that fly swarm.
Paper color

conclusion
 Then we use T-test ,F-test to compare different
between color and position .
From T-test ,F-test (color)show that
the ability in appeal housefly.
Pink=Green>Blue=Yellow
From T-test ,f-test(position) show that
Position1=Position2=Position3=Position4
Position doesn’t affect to interesting of fly.
And color affect to interesting of fly .
discussion
From our result find that kind of color can appeal
Fly, but it still have many thing to study.
1.Light that reflect to compound eye .If I put color paper on
sheet glass .Do you think paper can appeal fly?
2.Brightness of light If I do it in dark area ,can it appeal
fly .And what period intensity of light that color can
appeal fly.
3.Smell or kind of color that can appeal fly more.
If I put green color with syrup ,and put white color with
shrimp .Green or white that can appeal fly most?
