“EFFECTIVENESS OF MAKAHIYA (Mimosa pudica) AS AN ALTERNATIVE

“EFFECTIVENESS OF MAKAHIYA (Mimosa pudica) AS AN ALTERNATIVE OVICIDE AGAINST MOSQUITO EGGS/LARVAE.”

• Background of the study

• Conclusion

• Mosquitoes are one of the most unwanted and harmful pests known to man.

Based on the data gathered, we therefore conclude the following:

1. The Makahiya extract is an effective ovicide/larvicide for mosquitoes.

2. The Makahiya extract can be an alternative ovicide/larvicide for chemical ovicides.

• In feeding on blood, some of them transmit extremely harmful human and livestock diseases, such as malaria, yellow fever, filariasis and dengue. Some authorities argue accordingly that mosquitoes are the most dangerous animals on Earth.

• Throughout the history, many plants have been used as an alternative insecticide, ovicide, and repellents. Ovicides are any substances that are designed to kill eggs, especially the eggs of insects.

• Recommendations

• The Makahiya plant is widely distributed in the Philippines in open, moist, waste places, open grasslands and open thickets, at low and medium altitudes in settled areas.

1. The researcher recommended further experimentation of the Makahiya extract to improve the quality of the product.

2. The researcher recommended further experimentations on how to improve the color of Makahiya extract.

• Seed contains a toxic alkaloid, mimosine

• Documentation

• Results and Discussion

• Statement of the problem

This scientific study aimed with the investigation of Makahiya as an alternative ovicide against mosquito eggs/larvae.

Specifically, it seeks to answer the following questions:

1. What is the mortality rate of the mosquito eggs/larvae when exposed with:

A.

A.) T0 - 10 ml commercial ovicide/larvicide

B.) T1 – 40% makahiya extract and 60% commercial ovicide/larvicide

C.) T2 – 50% makahiya extract and 50% commercial ovicide/larvicide

D.) T3 – 100% makahiya extract

B. What are the effects of Makahiya extract (Mimosine) after having been exposed to the treatments within:

• 15 minutes of time

• 30 minutes of time

• 45 minutes of time

• 1 hour of time

2. What is the product’s effectivity in the shortest time 5-15 minutes?

3. How long will the product last?

• Hypothesis

3) After letting it cool down, measure the extract.

4) Pour the extract in the containers containing:

A.) T0 - 10 ml commercial ovicide/larvicide

B.) T1 – 40% makahiya extract and 60% commercial ovicide/larvicide

C.) T2 – 50% makahiya extract and 50% commercial ovicide/larvicide

D.) T3 – 100% makahiya extract

5) Collect mosquito eggs or “kiti-kiti”(mosquito larvaes) as samples. Add them into each treatment (10 eggs/larvaes each)

6) Observe the reaction and movements.

1. There is a significance that the product will be successful and can be used to lessen the population of mosquitoes.

2. There is a significance that the product’s effectivity it will be rated as Effective.

• Materials and Methods

Materials used:

• Mimosine extract from Makahiya • Containers labeled T0, T1, T2, T3

• Caserole • Strainer • Measuring cup

• Commercial ovicide/larvicide • Water

Procedure:

1) Using a boiling pan, boil the makahiya (leaves, stem, and roots), boil it up to 100C

2) Pour the solution through a strainer. Remove the leaves, stem, and roots and collect the extract and let it cool.

3) After letting it cool down, measure the extract.
