Laboratory Observations on the Mosquito Repellent Effect of Three Compound Essential Oils
A large number of mosquitoes and flies breeding on farms can spread insect borne viruses between livestock and poultry and between humans and animals,which not only causes economic losses to farms but also seriously threaten human health.The purpose of this experiment was to observe the mosquito repellent effect of three compound plant essential oils in the laboratory.According to the attack test method specified in the national standard GB/T 13917.9-2009,we used Kunming mice in this experiment to determine the repellent effect of three compound plant essential oils on Aedes albopictus.The results showed that the effective protection rates for Kunming mice were more than 70％within 2 hours for two kinds of mosquito repellent toilet water and 40％within 2 hours for the compound plant essential oil(APEX).Adjustment of the composition of plant essential oil APEX improved the effective protection time of compound plant essential oil APEX-1 to 2 hours and even enhanced the effective protection rate up to more than 80％within 4 hours.The adjusted APEX-2 also gained the effective protection time to 2 hours and even the effective protection rate reached more than 90％within 4 hours.The conclusion was that the compound plant essential oil(APEX)was an effective mosquito and fly repellent and even the effective protection rate reached more than 80％after adjustment of its composition.The compound plant essential oil(APEX)had the advantages of high efficiency,green and environmental protection,thus it had great application prospects for mosquito and fly repellent on farms.
