摘　　要：在河北省涞源县大豆玉米带状复合种植模式的苗期,调查中发现一种同时对大豆、玉米种子及其幼苗造成为害的地下害虫,通过形态和分子鉴定明确为灰地种蝇幼虫。本研究分别描述了该虫对大豆、玉米为害的症状,并通过对不同施肥处理田块被害情况的调查,发现施用未腐熟的有机肥田块为害较重。该研究可为大豆玉米带状复合种植模式下苗期规避该虫的为害风险提供指导。An underground pest causing damage to the seeds and seedlings of both soybean and corn within the soybeancorn strip intercropping field was discovered in Laiyuan County,Hebei Province.Morphological and molecular identification confirmed this pest as Delia platura.This study described the characteristics of the damage made by D.platura on soybeans and corn,respectively.Results from investigation into different fertilizer treatments revealed that the application of insufficiently decomposed organic fertilizer led to more severe damage produced by D.platura.The findings can provide guidance on mitigating the risk of this insect during the seedling stage in soybean-corn strip intercropping fields.
