Abstract: Objective To investigate the breeding of Carpoglyphus lactis in the storage Arillus longan， so as to provide the evidence for preventing the harm of C. lactis to traditional Chinese medicine. Methods Chinese herbal medicine warehouses were chosen as survey sites according to the breeding habits of mites， and the A. longan samples were stored more than 6 months. The mites were isolated and identified under a microscope. Result The C. lactis breeding rate was 20.0% （4/20） and the breeding density was 184.95 per sample. The constitute rates of adult， larva， dormancy body and egg were 58.39%， 30.41%， 0.06%， and 11.14% respectively. Conclusion The breeding density of C. lactis is high in the stored A. longan， so the control and prevention of human intestinal acariasis should be strengthened.

摘要： 目的 了解储藏中药材龙眼肉中甜果螨孳生率和孳生密度等，为预防甜果螨为害中药材龙眼肉提供科学依据。方法 依据甜果螨孳生习性，选取中药店作为样本采集场所，采集库存时间≥6个月的龙眼肉进行甜果螨分离并制做标本，光镜下观察其形态特征鉴定螨种，并参照Hughes （1976）的分类依据进行分类。 结果 本次采集的20份储藏龙眼肉样本中有4份检出了甜果螨，孳生率为20.0%；甜果螨的平均孳生密度184.95只/份；其不同发育期的构成比为成螨（含若螨）58.39%、幼螨30.41%、休眠体0.06%、螨卵11.14%。结论 储藏龙眼肉有甜果螨孳生，应防止甜果螨迁徙扩散为害其他干果和预防可能由其引起的人体肠螨病。
