Abstract

INTRODUCTION

This study focused on the insecticidal property of diris (Lantana Camara). This insecticide is not hazardous into our health because its contents are non-chemical. It is found eco-friendly and economical compared to commercial insecticides. Diris leaves have triterpenoids (lantadenes (lantadene A, B, C, D and icterogenin.) which is toxic to insects like mosquitos. Diris leaves have essential oils with major constituents of caryophylenne with 16.37%, eucalyptol 10.75%, a-humulene 8.22%, germacrene 7.41%, lantanol 0.22. This essentialoil isolated from leaves was for insecticidal activity against mosquitoes. The researcher got interested to conduct study on the properties of diris because Sta. Mesa Elementary School, Sta. Mesa, Mabini, Batangas, was situated along a 10-feet creek and surrounded by tall bamboo trees were insects most likely to breed and hide especially the mosquitos.

 

METHODS

The researcher used 1280 grams of diris leaves. The leaves were blanched, squeezed, and filtered in extracting juices. The extracted juices were placed in the centrifuge to prolong its shelf life. The test was conducted to 5ants, 5 mosquitoes and 5 cockroaches in two trials with a different number of spray applied during the first and second trials and observed for 5 minutes each trial.

 

RESULTS

The study revealed that the juice from diris leaves can be used as insecticide through spraying its juice directly to the insects. The numbers of sprays affect the effectiveness of diris as an insecticide. The diris insecticide was effective on mosquitos since after two trials with a different number of sprays applied mosquitos were not able to fly, feel dizzy then killed than in other tested insects.

 

DISCUSSIONS

Based on the results of the experiment, diris was effective on mosquitos founded on the comparison result done in the first and second trial with the same number of insects tested and length of observation. To combat the problem regarding the spread of disease caused by mosquito bites, the school personnel especially the teacher advisers should maintain cleanliness of the surroundings specifically their own classrooms. The rooms should be lighted well and free from any breeding grounds of mosquitos like flower vases with dirty water. School utility shall maintain the cleanliness of the area near thecreek side and fogging system of the barangay shall be done twice a week during rainy months.
