Journal Title: Shanghai Journal of Preventive Medicine - Year 2023, Vol 35, Issue 12
Abstract
ObjectiveTo investigate the population and chigger mite infection of rodents in Pudong Districtï¼ Shanghaiï¼ so as to provide the scientific basis for the prevention and control of rodents and chigger transmitted diseases.MethodsThe monitoring work was conducted in four points including Xuanqiaoï¼ Hangtouï¼ Laogang and Nanhui New Town with night trapping method from 2020 to 2022. Habitats as farmlandï¼ wastelandï¼ rural residential areasï¼ and parks were selected. The rodent species were identified and rodent density was calculated. All chigger mites were collected from the earlaps and auricular fossae of the rodents. The species of chigger mites were identified and the chigger mite index was calculated.ResultsA total of 222 rodents were captured. They belonged to 5 speciesï¼ 4 generaï¼ 2 families and 2 ordersï¼ including 4 speciesï¼ 3 generaï¼ and 1 family of Rodentia and 1 species of Insectivora. M. musculus was the dominant speciesï¼ with a composition ratio of 54.05%. Total 80 chigger mites were capturedï¼ with a detection rate of 36.03%. The total chigger index was 0.36 and Rattus tanezumi held the highest ï¼6.00ï¼ï¼ followed by M. musculus ï¼0.48ï¼. There were 3 species of chigger mitesï¼ L.delienseï¼ L.scutellareï¼ and L.gaohuense. L.deliense was the dominant specieï¼ accounting for 55.00%.ConclusionThere is a risk of chigger-borne disease transmission in Pudong New Area with M. musculus as the dominant host and L. deliense as the dominant species.
