储藏小麦中发现粗脚粉螨休眠体

目的观察储藏小麦中粗脚粉螨休眠体形态。方法采集安徽省临泉县储藏时间≥6个月的小麦样本,分离其中的粗脚粉螨休眠体,制备玻片标本,置于光镜下观察鉴定。结果光镜下可见粗脚粉螨休眠体的足及胫节毛和膝节毛等结构特征,足上的爪很发达,生殖毛基部和其两侧的1对吸盘几乎在同一水平线上。结论储藏小麦中可有粗脚粉螨休眠体孳生,应采取防治措施降低其对储藏粮食的危害。

Hypopus of Acarus siro found in stored wheat

Objective To observe the morphological characteristics of hypopus of Acarus siro in the stored wheat in Linquan County， Anhui Province. Methods The wheat samples were collected from the wheat which had been stored for more than six months. The hypopodes of A. siro were isolated from the stored wheat， and were made into the glass specimens， and then were identified under an optical microscope. Results The structural features of the hypopus were found under the microscope， such as the setae of tibia and setae of genu， and the foot claws were well?developed， and the genital seta bases and the pair of sucker were almost at the same baseline. Conclusion The hypopodes of A. siro are found in the stored wheat， and therefore， the effective measures should be taken to control the hazard to the stored grain.
