中药红花孳生谷跗线螨的调查研究

Investigation on Tarsonemus granarius breeding in the stored Chinese herb safflower

目的调查谷跗线螨在储藏中药红花中的孳生情况。方法选择安徽省芜湖、淮南、宣城市中药材仓库或/和药店的红花样本,采用直接镜检法和水膜镜检法分离谷跗线螨,光镜下鉴定和计数。结果在采集样品中发现谷跗线螨,孳生率为6.50%(13/200),平均孳生密度为6.12只/g(796只/130 g),不同发育期的构成比成螨为85.80%,幼螨为12.82%,螨卵为1.38%。结论储藏中药红花中有谷跗线螨孳生,在储藏和加工过程中应注意谷跗线螨的防制。

Objective To investigate the breeding of the mite Tarsonemus granarius in the stored Chinese herb safflower.Methods Samples of Carthamus tinctorius were collected from Wuhu, Huainan and Xuancheng in China. The mites T. granarius were isolated with directicopy and waternacopy, and identified and counted under the light microscope.Results The mites T. granarius were found in the stored Chinese herb safflower. The breeding rate and breeding density was 6.50%（13/200） and 6.12 heads/g（796 heads/130 g）, respectively. The composition of adult mites accounted for85.80%, young mites 12.82% and eggs 1.38%.Conclusion Our findings suggest that the mite T. granarius breed in the stored Chinese herb safflower, and this condition requires our attention to prevent and control.
