Objective To develop the long-acting mosquito repellent ointment and evaluate its slow-release performance and repellent effect on mosquitoes. Methods The mosquito Aedes albopictus was collected from the animal sheds of Fuzhou General Hospital of Fujian province during hours of 16:00-05:00 during spring and summer. The sustained release properties of long acting mosquito repellent ointment were evaluated by the percentage of volatile residue. Indoor test was carried out by national method "GB/T 13917.9-2009 laboratory efficacy test and evaluation of sanitary insecticides for pesticide registration", and the repellent effect and average protection time of mosquitoes were calculated. Results The homemade mosquito repellent ointment released DEET faster than the commercially available mosquito repellent cream by The Second Military Medical University, but it could also sustained releasing up to 12 h. The average indoor protection time of the DEET tincture was(3.98±1.14) h, the average indoor mean protection time of a commercially available mosquito repellent cream by The Second Military Medical University was(9.78±2.38) h, the average time for the protection of homemade mosquito repellent ointment was(10.11±2.22) h. Conclusion The self-made mosquito repellent ointment was better than the DEET tincture and the commercially available mosquito repellent cream by The Second Military Medical University.
