摘要
为了明确晋南棉花苗期地下害虫优势种类及为害的情况,采用“z字型十点”挖土取样法、性诱剂诱捕法、田间调查法,在棉花播种前调查棉田地下害虫的种类和数量,在棉花苗期3,6叶期,研究地下害虫优势种类对棉苗的为害情况。结果表明,金针虫、蛴螬、地老虎是棉花苗期地下害虫优势种类;不同地块、土壤类型、前茬和管理措施均对地下害虫有明显的影响。
To evaluate dominant species of soil insect pests and cotton seedling degree of damage in cotton field in southern Shanxi province. Z type digging soil, sex pheromone trapping, field investigation were used to investigate soil insect pest species,population number of each species and degree of damage. The result showed that grubs, wireworms, black cutworms were main dominant species in cotton field in southern Shanxi province.
