摘要
1995年以来对山西省金针虫种类、分布进行了系统调查和分类鉴定 ,结果表明金针虫在全省范围均有分布 ,计有细胸金针虫 (Agriotessubvittatus)、褐纹金针虫 (Melanotuscaudex)、沟金针虫 (Pleonomuscanaliculatus)以及林小金针虫 (Limoniusminutus)等 4种 ,其中尤以前三种分布范围广 ,为害严重。同时对金针虫分布地的海拔高度、土壤含水量、pH值 ,10cm地温、金针虫所在土深及前茬或当年茬口等理化性状进行了全面的调查 。
The barly wireworm are one kind of underground pests ,and distributed in most area of Shanxi province.In this paper, four species were found ,there were:Agriotes subvittatus、Melanotus caudex,Pleonomus canaliculatus and Limonius minutus.Among them,the Agriotes subvittatus, Melanotus caudex and Pleonomus canaliculatus were more important than the other species.In the paper,the elevation, soil moisture, pH value, the temperature and the depth of the pest in the ground were researched,the biological characteristics and behavior of every species were analyzed.Above all,the methods of controlling this pest were discussed.
