Objective: To investigate the breeding of Carpoglyphus lactis in stored jujube from Anhui Province, so as to provide the evidence for preventing the harm of C. lactis to stored jujube.
Methods: The jujube samples stored for more than 6 months were collected from dried fruit shops and/or Chinese herbal medicine warehouses, which were chosen as survey sites in Anhui Province. The mites were isolated and identified under a microscope.
Results: Totally 19 samples infested with C. lactis were obtained from 300 samples in 17 cities of Anhui Province, the breeding rate and breeding density of C. lactis were 6.33% and 6.52 per gram respectively. The constituent ratios of different developmental stages were adult 85.72%, larva 12.27%, dormancy body 0.56%, and egg 1.45%, respectively.
Conclusions: The breeding density of C. lactis in the stored jujube is high and the species diversity is rich, so the control of C. lactis and the prevention of human acariasis should be strengthened.
[摘要] 目的 了解安徽省储藏大枣中甜果螨孳生状况。方法2016年10月-2017年7月, 从安徽省17座城市30家干 果商店或/和中药材仓库采集大枣 (储藏时间≥ 6个月), 并进行甜果螨分离, 观察大枣中甜果螨孳生情况。结果 从安徽 省17座城市共采集了300份大枣样本, 其中19份检出甜果螨, 甜果螨孳生率为6.33% (19/300), 平均孳生密度为6.52 只/g; 不同发育阶段构成比为成螨 (含若螨) 85.72%、幼螨12.27%、休眠体0.56%和螨卵1.45%。结论 安徽省储藏大枣中 甜果螨孳生密度较高, 应采取相关措施防止甜果螨向其他干果或中药材扩散。.
