ABSTRACT

Cockroaches are the most noted pests insects due to their population. Cockroaches are also the hardiest insects on the planet because they have a capability to stay live for a month without food. The high price and health risks problem from food branded chemical insecticides gives dilemma to Filipino household. Respiratory diseases can also get from chemical insecticides inhaled by a person. This study seeks the possibility of using the extracts of Calamansi and Onion as an effective cockroach killer.

The Calamansi and Onion extract as cockroach killer can be possible by the Botanical ang Chemical Properties that can be naturally found within the fruits. Calamansi have a chemical property called d-Limonene which have the capacity to suffocate and destroy the respiratory tract of an insect.

In making the insecticide,squeeze the Calamansi until the extract reaches the measurement. Slice the onion into smaller pieces then crush with juicer. For additional d-Limonene substance that melt the wax coating of insects, add some orange oil that is made by leaving the peels in a jar with alcohol then place in a sunny place. To finish the product, mix all the extracts into a sprayer. Add salt to make the product long-lasting. To test the effectiveness of this product, we used two set-ups; two boxes with ten cockroaches each inside.

From the test that the researcher conducted, it revealed that there is a significant difference between the effects of the prepared product and the commercialized product with the calculated t-ratio of 10.62 which is higher than the tabular value of 2.262 at 5% level of probability and 3.250 at% level of probability.

ACKNOWLEDGEMENT

We would like to expres the deepest gratitude to the following without their help,this project would not possible:

I.INTRODUCTION

A.BACKGROUND OF THE STUDY

Cockroaches are insects of the order Blattaria or Blattodea of which about 30 species out of 4500 total are associated with human habitations. About four species are well known as pests. Cockroaches are one of the oldest groups of insects, indicating how successful they have been in adapting to changes in their environments. One of the reason for this success may be related to diet –they are scavengers and will eat anything organic. They prefer food sources such as starches,sweets, grease, and meat products, but other itmes may include cheese, beer, leather, glue, hair, and starch in book bindings, flakes of dried skin or decaying organic matter(plant or animal)

Calamondia or Calamansi, Citrofornella microcarpa, belong to the fruit tree family rutaceae. The fruit of the Calamansi is a small,round lime, a little bigger than the size of a thumbnail, about 30mm(an inch) in diameter. Similar to other citrus fruits, the calamansi is high in vitamin C, and the juice can be an excellent vitamin basis. The lively D-limonene as destroys the wax coating of th insects respiratory system. As soon as applied directly, the insect suffocates.

The Onion (allium capa), the name approach from onion or the singleness as a bulb. The plant is interconnected to the lily botanically; chemically it is less piquant cousin of th garlic in taste, but it is distinctive in its lachrymatory properties. It is...
