Composition and diversity of Acaroid mites’communities in indoor environ-ments of kindergartens in Wuhu City / 中国血吸虫病防治杂志

ABSTRACT

Objective To understand the breeding situation of Acaroid mites in indoor environments of kindergartens in Wuhu City so as to provide the evidence for its prevention and control. Methods From March to June and September to De?cember in 2014 dust samples were collected from 15 kindergartens of 3 ranks every month. Acaroid mites in the samples were isolated identified and counted. Results Totally 360 samples were selected and 169 samples 46.94% had mite infestation. Pyroglyphidae accounted for the most in the population with the breeding rate of 45.00%. Totally 18 504 mites were found and Dermatophagoides farina and Dermatophagoides pteronyssinus were the dominant species with the composition ratios of 30.21%5 590 mites and 17.83% 3 300 mites respectively. The third?ranked kindergartens were in the most serious situation con?cerning with 81.67% 98/120 of the breeding rate of Acaroid mites. The differences were statistically significant among the kin?dergartens with different ranks F=6.048 χ2=73.523 both P0.05 . Conclusion Acaroid mites in the kindergartens in Wuhu City were in serious condition and the population and species composition of Acaroid mite community is influenced by the human behavior and indoors environments.
