储藏根茎类中药材孳生书虱种类研究

Investigation on thespecies of booklice breeding in the stored Chinese root- stock medicinal materials

本研究从安徽淮南采集储藏根茎类中药材样本共30种,采用直接镜检法和光照驱虫法分离其中孳生的书虱,光镜下鉴定书虱种类并计数。结果表明,30份样本中书虱的孳生率为93.3%(28/30),检获的书虱为嗜卷书虱(Liposcelis bostrychophila Motschulsky,1852);该书虱年平均孳生密度为57头/克,孳生指数为142。本研究表明安徽淮南部分储藏根茎类中药材有书虱孳生,在中药材储藏和加工过程中应注意书虱的防制。

A total of 30 samples of the root-stock medicinal herbs were collected from the herbal storehouses and pharmacies in areas of Huainan The booklice which were isolated with directicopy and redricopy were identified and counted under the light microscope The results show that the booklice were identified in 28 of the 30 samples （933%）, and represented as （Liposcelis bostrychophila Motschulsky, 1852）. Annual breeding density was 57 heads/g and breeding index arrived at 142 The investigation show than booklice infestation appears serious in parts of the Chinese traditional root-stock medicinal materials in Huainan areas This condition entails positive prevention and control of the booklice breeding in storage and processing of the semi-finished herbs
