广州小麦粉成品车间书虱年度发生跟踪监测研究

Study on Detection of Psocids Annual Occurrence in Wheat Flour Warehouse in Guangzhou

采用瓦楞纸板诱捕器,对小麦粉成品车间2017年3月至2018年2月期间书虱的发生情况进行跟踪监测,并利用地质统计学等高线绘图技术统计分析小麦粉成品车间书虱发生部位以及与温湿度的关系。年度跟踪监测表明,在小麦粉成品车间累计诱捕到书虱25131头,呈非均匀分布。书虱诱捕数量与车间内温湿度有密不可分的关系,其发生部位主要为麸皮打包间、麸皮打包间和成品仓交接区域、自动打包机和皮带输送机区域、卸粮口区域,且具有长期持续存在向周围扩散虫害的危险。在实际生产中可根据书虱发生部位开展有针对性的防治措施。

Psocids occurrence was detected in flour warehouse from March-2017 to February-2018 by a corrugated board trap.The location of psocids and its relationship with temperature and humidity were analyzed by geostatistics contour mapping technology.The results showed that 25131 psocids were caught in the flour warehouse which indicated that psocids were in nonuniform distribution in the warehouse,and the number of psocids closely related to the temperature and humidity of the flour warehouse.The infestation hot spot of psocids was Bran Packing Room,the junction region with Bran Packing Room and Flour Storage Room,the area of Auto Baler Machineand Belt Conveyor,and Grain Unloading Tunnel.The distribution hot spot area of psocids had characteristics of long-term persistent existence,and had risks of spreading outside.In practical production,targeted prevention measures can be taken according to the distribution of hot spots of psocids.
