           The study was conducted to determine the effectivity of Yellow Oleander (Thevetia Peruvia Pers.) against termites. Furthermore, it sought to determine the effectiveness of following parts: stems, fruits, flowers, and leaves as termicide. Samples were conducted and subjected to blending. 100% concentration of the extract placed in spray bottles was used against the test organisms. The produced termicides were then sprayed into their respective glass jars containing ten (10) termites per application in every trial. The effect of the termicide on termites was observed.

Furthermore, four parts were chosen for this test: stem, fruits, flower and leaves. This study was conducted at Mannan’s residence, Poblacion, Bongao, Tawi-Tawi on the month of April 2022, to test the potential of Yellow Oleander in killing termites. Hence, the researchers employed a three-time spray application on termites to determine its mortality rate. Overall, there were one hundred (120) termites collected in this study per application. Hence, the researchers hypothesized that there is no significant difference on the effects of different parts of Yellow Oleander as termicide.

Based from the results, the researchers found that the leaves extract showed the highest mortality of termites which is obtained a mean of 63.45% in all three trials. While, the fruits extract obtained the least mortality rate of 47.78%. The leaves extract also showed the highest mortality of termites which is obtained a mean of 62.90% in all applications. While, the fruits extract obtained the least mortality rate of 47.67%.

All parts the (leaves, stem, flowers and fruits) showed remarkable effectivity against tested termites-with the stem extract showing fastest termicidal effectivity among all yellow oleander parts with only 4.28 minutes. While, the flowers extract obtained the slowest termicidal effectivity of 11.08 minutes.

          In addition, based on the analysis of data using One-way ANOVA, a significant value was obtained. This implies that different solution of termicide using Yellow Oleander showed different effect that leaves, fruits, stem, and flowers have significant differences in terms of terminating termites which rejected the hypothesis employed in this study. However, stem extract is the most effective one.
