INVESTIGATORY PROJECT

"MAKABUHAI AND CHILI EXTRACT: A HOUSEHOLD INSECTICIDE"
Title
CHAPTER I
  • INTRODUCTION:
An ant lives everywhere on land, being the most numerous in insect species.They live on underground and create those earthier mounds. Some lives on trees and some on hollow parts of certain plants. They can be considered as a menace in our kitchen and dining hall.

Cockroaches have been a problem to many of us. They may contaminate our food with the filth they carry, and causes sickness. And it's so hard avoiding these things because they come and go whenever, wherever.

These insects are pests once they are allowed to multiply. To control these pests, chemical insecticides are usually used in many of us but there are many harmful effects in using those chemicals. Among those are dangers they threaten on our surroundings. It causes and adds to pollution.

Some plants produce a distinctive chemical or odor that can drive away insects. Realizing the good potential of these plants in controlling insects, botanical or organic materials are used now, being considered instead of wide spread use of chemical ones. Since some of this plants are commonly growing in our backyards, they are inexpensive and environment friendly.

This study uses the extract of chili and makabuhai plant to control pests in our house. The makabuhai extracts contains bitter substance and chili produce spicy like taste and smell. It is possible that this taste and smell is offensive to insects.

  • STATEMENT OF THE PROBLEM
1.) Is it effective?
2.) Is it environmental friendly?
3.) Is it cheaper than the commercial ones?

  • HYPOTHESIS
1.) YES, it is effective
2.) YES, it is environmental friendly since this plants are commonly growing in our backyards.
3.) YES, because we can find these plants in our backyards.

  • SIGNIFICANCE
This study investigates the potential of the makabuhai and chili extracts combine together as a household insecticide against ants and cockroaches. The mixture was made into a solution with little water and sprayed onto ants and cockroaches at varying concentrations.

CHAPTER II
  • REVIEW OF RELATED LITERATURE
Hot chili pepper ( capsicum Annum ) sweet and spicy ( fructeseeds Solanceae ) belongs to the same botanical family as potato, tomato, eggplant and tobacco. They are thouht to have been used first in mexico around 7000 BC, Columbus brought them to european 15th century. Peppers made their way around the world and were brought to north america with european colonists chili peppers are found in abundant and cheap on philippine market. Chili pepper plants are decorative in your garden or home. Chili pepper plants grow in tropical or subtropical climate zones.

Makabuhai plants ( tinospora Crispamenaspermacea) is a woody climber up to 15m long, older stems with numerous prominent priotusions, leaves broadly heart shaped, flowers with 3 petals, fruit an ellipsoidal drupe. Orange up to 2cm long. It's stem contains a very bitter milky sap. In primary rainforest or mixed decidous forest throughout the philippines. In tropical area at altitude up to 1000m. Bitter taste is not agreeable to most people.

CHAPTER III
  • METHODOLOGY
MATERIALS: Chili( 300g )
Makabuhai Stems ( 300g )
Mortar and Pestle
Beaker
Graduated Cylinder
Piece of Cloth
Spray Bottle
Stirring Rod
Water
PREPARING FOR THE CHILI EXTRACT:
1.) Collect enough hot chili at least 300g.
2.) Pound them with mortar and pestle.
3.) After the juice is extracted, add 25ml of water.
4.) Strain the chili extracts and out it in a beaker, set aside.
PREPARING FOR THE MAKABUHAI EXTRACT:
1.) Weigh 300g of makabuhai stems.
2.) Chopped it into small pieces and then pound it with a mortar and pestle.
3.) Soak the pounded stem in 25ml water for 25 minutes.
4.) Take the stems out of the container and extract the juice.
5.) Mix the chili and makabuhai extract and add 25ml of water.

(NOTE:To avoid being exposed to the solution, use gloves and goggles.)

CHAPTER IV

  • RESULTS AND DISCUSSIONS
I, the researcher observe for only 30 minutes if the makabuhai decoction and chili extract can kill insects by testing it to the specific insects, which are ants and cockroaches.



NUMBER OF TEST

TEST 1
TEST 2
TEST 3

NUMBER OF SPRAY

4 SPRAYS ON TEST 1
7 SPRAYS ON TEST 2
9 SPRAYS ON TEST 3

NUMBER OF COCKROACHES KILLED

2 COCKROACHES WERE SENT TO HEAVEN
4 COCKROACHES WERE SENT TO HEAVEN
5 COCKROACHES WERE SENT TO HEAVEN


The information above shows the number of cockroaches being killed by the makabuhai decoction and chili extract. And i compare it to a commercial one that it is almost the same.
