摘要
目的调查蚌埠地区4种常见仓储粉螨腐食酪螨(T.putrescentiae)、粗脚粉螨(A.siro)、害嗜鳞螨(L.destructor)、粉尘螨(D.farinae)在20种不同孳生物中的孳生及其季节消长情况。方法2006年2月—2007年1月,每月从蚌埠市面粉厂、市场、药房、学生宿舍等选取20种不同生境采集样本,运用水膜镜检法、电热集螨法进行分离计数,并制片鉴定。结果4种粉螨在火腿、小麦、菜籽、居室灰尘中孳生密度较高。一般在4—5月开始大量孳生,7—8月达到最高峰,9—10月迅速下降,不同螨种季节消长有所差异。结论蚌埠市区4种常见粉螨孳生环境广泛,季节消长特征较鲜明,可据此采取相应防制措施。
Objective To investigate the breeding densities and the seasonal distribution of Tyrophagus putrescentiae, Acarus siro, Lepidoglyphus destructor, and Dermatophagoides farinae in Bengbu City, 4 common storage acaroid mites during Feb.2006-Jan.2007. Methods The samples were collected and isolated by Waterflotation and Tullgren, then counted and identified the four acaroid mites from 20 different habitats. Results 4 species of acaroid mites had high breeding density in ham, wheat, seed and house dust. The number of the mite increased from Apr. or May, and to the peak during July and Aug. and declined from Sep. or Oct.. Seasonal distribution of the individual acaroid mites might be different. Conclusion 4 species of acaroid mites are widely distributed in Bengbu city with distinctive seasonal distribution.
