Objective To analyze the application of national standard of vector density for pest control performance evaluation in creating hygienic city, to provide a scientific reference for the control and prevention of urban vectors, create hygienic city and meet special vector inspection. Methods Urban vector special inspection was conducted based on national standards of vector density for pest control performance evaluation. Results Total 64 counties of 8 cities in Shaanxi were inspected within 4 years, and the indexes that were most likely to reach grade A were index of mosquito landing rate, positive rate of cockroaches ootheca, the density of rodents in outdoor environment, cockroach infestation trace rate, mosquito density in large and medium-sized water bodies, of which the achieving rates were 93.06%, 85.29%, 82.61%, 57.35%, and 55.56% respectively. The indexes that were more difficultly to achieve Grade C were density of mosquito in smaller ponding, facilities for preventing fly, indoor fly density, being 26.39%, 16.67%, and 16.67% respectively. The average rate of non-achieving standard in areas where "flies were prohibited" was 37.31% and the flies positive detection rate of this index showed the obvious downward trend year by year. Conclusion The new national standards are more scientific, standardized, and high maneuverability. Two indexes including mosquito density in small water body and the rate of in areas where "flies were prohibited" were more difficult to reach the national standards.
