    摘要:

    通过开展我国7种主要储粮害虫在实验室条件下对方向的趋向性活动规律研究,为储粮害虫在实仓的监测和防控手段提供指导。结果表明赤拟谷盗、嗜卷书虱、米象具有显著趋光性,杂拟谷盗趋北方位活动,玉米象则在24 h内显著趋东方位活动;无光照来源时,嗜卷书虱显著趋北向。研究结果揭示的储粮害虫对方向的活动规律可为实仓监测和诱集提供应用参考。

    Abstract:

    For monitoring and controlling stored grain pests in grain storage, the tropism of natural activity of seven main stored grain pests were studied under laboratory conditions. The results showed that the Triboliumcastaneum (Herbst), Liposcelisbostrychophila Bodonnel and Sitophilusoryzae (linnaeus) showed strong tendency towards east and north when the light source was at the east and north, the Triboliumconfusum Jacquelin du Val towards north, and the Sitophiluszeamais Motschulsky towards east. The Liposcelisbostrychophila Bodonnel obviously trends to north when there is no light source. The results of the study can provide a reference for the field monitoring and trapping.
