我国赤拟谷盗地理分布研究

赤拟谷盗(Tribolium castaneum(Herbst))是我国的主要储粮害虫,但近年来有关其在我国的地理分布研究少有报道。本研究采用采集、诱捕相结合的调查方法和形态鉴定方法,研究、明确了当前我国赤拟谷盗的地理分布。来自我国23个省(区)56家粮食仓储单位的调查结果显示,已在19个省(区)32家仓储单位采集到赤拟谷盗成虫;西藏4家单位、青海3家单位、甘肃省2家单位均未采集到赤拟谷盗;黑龙江省5家单位中的3家、吉林7家单位中的2家单位有极少量的赤拟谷盗。研究结果表明,赤拟谷盗在我国至少23个省(区)有分布,西藏、青海、甘肃在本调查中未见样品;在过去的60余年中,赤拟谷盗已从东南沿海个别省(区)扩散到了大部分省(区)内;建议我国进一步加强国内粮食调运过程中赤拟谷盗的防控工作,保护好储粮和生产安全。

Geographical distribution of Triboliumcastaneum(Herbst) (Coleoptera: Tenebrionidae) in China

Tribolium castaneum (Herbst), red flour beetle, is one of the main economically important stored grain insect pests in China but there are few studies about its geographical distribution. The geographical distribution of T. castaneum in China was studied and confirmed using integrated methods of manual and trapping collection. According to the results of the survey in 56 grain storages of 23 provinces, the adults of T. castaneum were collected in 32 storages of 19 provinces. The red flour beetle had not been collected in 4 storages of Tibet, 3 storages of Qinghai, and 2 storages of Gansu. Three of 5 grain storages in Hei longjiang and 2 of 7 storages of Ji lin had the a few collections of red flour beetle. Research results showed that T. castaneum had distributed at least 23 provinces of China, however without collections in Tibet, Qinghai, and Gansu provinces in this research. It presented T. castaneum had spread into most provinces from the southeast coast of China during nearly 60 years. In order to protect stored grain well, We suggest to strengthen the prevention and control of T. castaneum furtherly in some related provinces.
