After human body exposed to the repellents with the dosage of 1.5 μl/cm² (liquid state) or 1.5mg/cm² (gel state), the experimental results indicated that the average effective repelling times of PD type repellents to Aedes albopictus was between 10 and 11 hours; The effective protect rates after being used of 12h were 92.3%、91.2% and 88.9% separately. The PD type repellents were all superior to the other kinds of control types in repelling effectiveness, and have the advantages of easy to use and no sense of oily.
