摘　　要：本文记述了在内蒙古扎兰屯市绰尔河农场大豆上发现的一种根蛆类新害虫。为了明确该根蛆的分类地位及其对大豆苗期植株的为害特征。将根蛆虫源采集回室内进行人工饲养,利用形态学方法鉴定害虫种类以及描述各虫态形态特征。并采用现场随机五点取样法对其田间为害症状及危害程度进行多点调查。结果表明:该根蛆在大豆田间以幼虫钻蛀为害幼苗根茎,被害后植株萎蔫枯死,导致缺苗断垄,受害严重的地块被害株率达22%,在田间土壤中可转株危害。种类鉴定结果显示该害虫为灰地种蝇[Delia platura(Meigen)],在国内首次发现为害大豆。为了便于田间识别和防治,根据该害虫与国内已报道的其他3种可危害大豆的根蛆类害虫的形态差异制作分类检索表。A new root maggot pest was investigated and described in Chuoerhe Farm in Zhalantun City of Inner Mongolia. This study aimed to clarify the classification status and damage characteristics of soybean seedling root maggots. Root maggots were collected and artificially reared indoors, species were identified by morphological methods, and the morphological characteristics of each insect stage were described. A multi-point survey of the symptoms and damage on the site was used to conducted with the method of a random five-point sampling. In soybean field, this pest bored the rhizomes of seedlings by larva and caused the appearance of wilt and death, resulting in the lack of seedlings and ridge breakage. The percentage of infected plants was 22% in the seriously damaged plots. This pest can be transferred into other plants in field. The species identified the root maggot as the root maggot was Delia platura(Meigen). It is firstly found that this pest damaged cultivated soybean in China. In order to facilitate identification and control in the field, a classification key was compliled based on the morphological differences between this pest and other three kinds of root maggot pests reported in China that can harm soybean.
