THE PROBLEM AND ITS BACKGROUND
Various known plants in the Philippines are considered as weeds. One of which is the Tithonia diversifolia that is commonly known as Wild Sunflower. While it is considered as wild plant, it is also recognized for its significant uses in poultry, agricultural industry and pesticide industry and medicine.
The uses and significance of wild sunflower in the Philippines are yet to be introduced and popularized. Wild sunflower, a shrub, can be spotted by the roadside. Aside from the nutritional components that can be obtained from its leaves, reports indicate that the extract from the leaves contains insecticidal properties.
One of the most successful of all insects, ants can be a serious nuisance pest in homes, hospitals, restaurants and other buildings. Their ubiquitous nature and social structure make them particularly difficult to control. Small proportions of ants feed on and contaminate our food stuffs that make us consider them as pest on our homes and buildings.
The most effective way of inhibiting damages caused by household ants is to ward off these pests using suitable methods.
II. STATEMENT OF THE PROBLEM
The aim of this study is to utilize these plants for the production of insecticide because of their insecticidal properties. Specifically, it aims to answer the following questions: 1. What is/are the insecticidal component/s of the Tithonia diversifolia leaves extract? 2. How does the aqueous extract solution compare to the commercially-available insecticides in terms of the following: 2.1 Physical properties
2.2 Chemical Properties
3. Is there a significant difference between the aqueous extract solution and the commercially-available insecticide in terms of physical and chemical properties? 4. What is/are the effect/s of the solution on the subjects being tested?
III. NULL HYPOTHESIS
There is no significant difference in the properties of the aqueous extract solution compared to the commercially-available insecticide. IV. SIGNIFICANCE OF THE STUDY
The research involves the use of Tithonia diversifolia leaves extract as control against common household ants. This study can help to define other possible uses for the plant other than being used as ornaments.
This study aimed to the lessen dependence on commercially-available insecticides.
This study offers an alternative feedstock in the production of insecticide. The expected cost of production will also be significantly less since the source would be easily accessible as it is a widely spread shrub growing on plains and near roadsides.
This study also benefits the members of the community by providing an alternative solution to the problem of ant infestations in the household. This study aimed to provide scientific basis for the wild sunflower leaves in insecticide. It is hoped that this information can be used for the possible exploitation of this species for various research and insecticide purposes.
This paper is hoped to serve as reference for future studies relating the same field.
V. SCOPE AND LIMITATIONS OF THE STUDY
This research focuses on using the extract of Tithonia diversifolia as control for common household ants. This study discusses the insecticidal component of the extract and how it compares to the commercially-available insecticide in the country.
This study utilizes processes such as drying, pulverizing, dissolving, settling, filtering, evaporating and mixing to obtain the aqueous solution using the Tithonia diversifolia leaves.
This study also examines the possible methods of application of the extract as an ant control. This experiment is limited to common household ants, which can be seen in most households.
The study does not include the percentage mortality of common household ants...
