2. Problem state:
 As a problem reported by our students
who are originating from Africa. Our
school is an İnternational school. They
clearly stated that their we can find a
solution for flies and insect which cause
diseases and many families find a hard
time to get a remedy for this situation.

3. THE NEWS:
 TRT NEWS – 15 February 2012
 The tsetse fly kills by spreading a sleeping
sickness. Africa as whole is in trouble due to this.
This flyi mainly leaves on other animals as a
parasite and feeds on blood. This way it carries
the sickness.
 (Tsetse fly does not live and exist in our present country. That’s
why we preferred to use fruit flies in carrying out experience)

4. CHEMİCAL İNSECT REPELLENT DAMAGES:
 In accordance to a point reached by the French scıentıst the chemıcal called
“DEET’ which is contained in mosquito drugs, has a neurotoxic effect on the
human nervous system. This substance breaks down the acetylcholinesterase
enzyme, which has a very large prescription for the central nervous system.
 It involves high risk for pregnant women. In order to neutralize the flies, a
substance called DEET is used in ınsect repellent . This item can be effective not
only on mosquitoes but also on human lıfe. According to the investigations
made, approximately 16.7% of this material is absorbed into the blood and
passes from there to the placenta. In pregnant women, this substance can infect
babies.

5. Purpose:
 We have seen that the fly drugs
used today are harmful and
expensive. In the literature, we
noticed that in the rural area,
especially on the basil leaves,
When we ask our dearest, he
directed us to these vegetable
oils.

6. Process:
 To get the orange oil ourselves, we chopped the oranges we
took from our meals and put them in the alcohol solution.
We extracted orange oil by extraction method. We got help
from our biology colleagues to train ourselves. We put
orange, lemon, apple pieces in front of the laboratory glass
(we chose red apples) We waited for the flies to come and
lay. When we did this process in February, our flies could not
reproduce. We tried to solve them on the flies we caught on
it.

SOLUTIONS USED:
ORANGE BASİL ALMOND GERANİUM ALCOHOL

17.  From these solutions we poured 10 drops of drip onto the filter paper and put it in
the empty beaker where the flies were found. And we recorded the time.
 20 seconds in the orange oil,
 25 seconds in geranium oil
 30 seconds in basil oil
 We realized that it was killing the flies.

18. We tried mixing
the orange and
basil oil together.
We realized that
it was killing the
flies in about 15
seconds.

19.  After we saw that we were successful, we had 2 bottles of water
bottles of 5 liters in the hobby garden of our school. We put
meat and orange pieces in these bottles. We opened the door.
After 10 days, our flies multiplied. We tried these herbal
solutions on them again. We calculated the volume of the
empty aquarium. The volume of the aquarium was 0.6365m3,
the volume of the beergar was 0.000105m3. We used two
drops of solution for beergar. For the aquarium, it would be
sufficient to use a solution containing 121 drops of orange and
basil oil.

20. CONCLUSION AND RECOMMENDATIONS:
 The most effective solution we did was an orange-basil mixture. It can also be used in
areas where our body is open as a lotion. Oranges are products produced in abundant
quantities in our basil country. We can get 2 liras from the orange market, 5 liras from
the bloom. It will be more economical than oil to buy orange oil for ourselves for 15
liras.
 The products we use do not harm the environment and people. It does not smell as
bad as most flies in the market. It has a nice and refreshing smell.
 We see that there are many damages when we read the information on the chemical
fly drugs. But our product is completely and totally organic, there is no harm.

22. Extensibility:
When our African friends return home for summer
vacation, they will be able to take these medicines with
them and try them there. And they will share the results
with us when they return.
