The Insecticidal Activity of Acacia Bark Extract on the Mortality Rate of Rice Earhead Bug (Leptocorisa Oratorius)

Synthetic pesticides have been widely used in agriculture, despite their harmful effects on the environment and human health. In response to this, there is a growing need to explore alternative methods of pest control. This study aimed to investigate the effectiveness of acacia bark extract as an organic insecticide against rice earhead bug (Leptocorisa oratorius) with the goal of reducing reliance on synthetic pesticides. The treatment were as follows: Treatment 1 (Acacia bark extract obtained through boiling for 1 hour), and Treatment 2 (Acacia bark extract obtained through soaking for 5 days). Results analyzed statistically through the use of the scale that the researchers made, and it was found that Treatment 1 was more effective in managing rice earhead bugs compared to Treatment 2. Treatment 1 exhibited rapid action and immediate reduction of pest populations, making it ideal for quick mitigation during critical growth stages. Additionally, both treatments were effective in achieving 100% mortality of rice earhead bugs, but Treatment 1 consistently reached this outcome faster. However it is recommended to make a formulation to reduce the unpleasant aroma of the organic insecticide. Adding a few drops of essential oils, such as lavender or citrus, can mitigate the extract’s unpleasant odor while enhancing its insecticidal properties. Moreover, if the extract is in a sealed container in a cool, dark place it can prevent the odor development over time.
