摘要
目的调查芜湖市高校食堂中孳生螨类的物种组成及其生态指数。方法采集芜湖市高校食堂(就餐大厅、物品储存间和面粉制作间)的地面灰尘和面粉样本,用直接镜检法和水膜镜检法分离样品中螨类,然后镜下制片、鉴定和计数。结果共采集样本161份,其中检查出螨类54份,阳性率为33.54%(54/161);鉴定出螨类8种,隶属于5科7属。平均孳生密度最高为36.38只/g(384/468.60)。结论高校食堂场所有螨类孳生,应重视高校食堂螨类的检测及防治工作。
Objective To investigate the species composition and ecological index of mites in the college refectories in Wuhu city. Methods The floor dust and portion of flour were respectively collected from the dinning hall, goods storage and wheaten food preparation room in the college refectories in Wuhu area, and subjected to separation of the mites by direct microscopic examination or water film microscopy. Mite speci- mens were prepared under the microscope, and then identified and counted. Results Mites were detected in 54 of the 161 samples collected, with a positive rate of 33.54% （54/161）. Eight mite species were identified, representing 7 genera under 5 families. The average breeding density was 36.38 heads/g （384/468.60）. Conclu- sion Mites appear prevalent in the dinning areas and food materials in the college refectories in Wuhu, suggest- ine that these places should be strengthened bv regularlv specified test to prevent the mite infestation.
