Pesticidal Property of Siam Weed Leaves (Chromolaena odorata) on Houseflies (Musca domestica)

Abstract

INTRODUCTION

Houseflies are some of the hated and the most problematic pests in the Philippines because they could transmit bacteria and disease to the local citizens. Siam weed (Chromolaena odorata) locally known as hagonoy or hagonoi is a highly invasive plant species which is poorly studied even though it's hard to eradicate, a nuisance in plantations and known to harm agriculture farm and commercial plantations. It contains bio-active chemicals suitable and alternative biocontrol substance and also contains phytochemicals that serve as repellent or may kill insects. in this study, we extracted the Siam weed leaves and created a solution to minimize this problem since there is no existing alternative in the locality.

METHODS

An experimental method was used to test the pesticidal properties of Siam weeds leaf. Three trials were conducted to three treatments to test the effectivity of Siam Weed leaves extract. The same amount of solution was measured, and houseflies were tested during the trials on Baygon (Positive control), Siam Weed (Experimental group), and water (Negative control).

RESULTS

Table 1 Comparison of Time of Survival of Houseflies in different treatments.Two treatments had an effect in eradicating the insects. in terms of the time survival of houseflies they have different results. However, tap water treatment indicated no effect.

DISCUSSIONS

There is a significant effect on the trials applied using the extract of Siam Weed leaf on houseflies. It implies that it can be an alternative pesticide. It is more convenient since it is available in our surroundings, less expensive and organic.
