Miniproject :Find color appeal to fly most
member
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 visionSome 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)
IntroductionNowadays, 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?
First we catch fly but we don’t made future board in aquarium then we found that fly can escape this.
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.

conclusion Then we use T-test ,F-test to compare
different between color and position .From T-test ,F-test (color)show thatthe ability in appeal housefly.Pink=Green>Blue=YellowFrom T-test ,f-test(position) show thatPosition1=Position2=Position3=Positi
on4Position doesn’t affect to interesting
of fly.And color affect to interesting of fly .
discussionFrom our result find that kind of color can
appealFly, 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?
