Abstract

Mosquitoes that spread viruses are called vector mosquitoes and can be extremely dangerous to humans, but bites from other mosquitoes can also lead to side effects such as itching, irritation, or swelling. Rice bran oil has not yet been tested as a repellent, but it possesses very similar properties to mustard seed oil, which has been proven to have insect-repelling tendencies by previous studies (Mukesh et al., 2014). Discovering novel repellents is necessary because of recent studies that have been conducted regarding the resurgence of mosquito-borne diseases like arboviruses and malaria (Dahmana & Mediannikov, 2020). The purpose of this study was to determine the ability of rice bran oil as a mosquito repellent. The mosquito-repelling abilities of various essential oils that have been proven to be effective in preventing mosquito contact were compared with rice bran oil and mineral oil. It was hypothesized that rice bran oil would have significantly less mosquito landings than the odorless oil, as rice bran oil has a similar composition to mustard seed oil, an effective mosquito repellent. The number of mosquito landings in each oil was counted, as a significant number of mosquito landings would classify a compound as an ineffective repellent. A one-way ANOVA was conducted and found a significant difference between at least one pair of means, with F(4,70)=86.78, p<0.001, and a Tukey test showed a significant difference between the rice bran and mineral oil. Rice bran oil acted as an effective repellent in the experiment.
