<![CDATA[This research is based on the need for environmentally friendly alternatives to chemical insecticides. To determine the potential of ethanol extract of jasmine flowers (Jasminum sambac L.) as a repellent against houseflies (Musca domestica). The study employed a post-test only control group design with ethanol extract concentrations of 15%, 20%, and 25%, along with a positive control (Venox fly repellent spray) and a negative control (distilled water). The effectiveness was assessed by counting the number of flies that landed and were repelled. Data were analyzed using probit regression to determine the ED₅₀ and ED₉₉ values. Higher extract concentrations resulted in stronger repellent effects. A 15% concentration produced a repellency rate of 34.37%, 20% achieved 51.64%, and 25% reached 80.61%. The ED₅₀ was found at 16.494%, and the ED₉₉ at 38.222%. Ethanol extract of jasmine flowers has the potential to serve as an effective natural bioinsecticide for controlling houseflies.]]>
