摘　　要：根寄生杂草列当Orobanche spp.每株可产生大量细小的种子,易于传播,且在出苗前已经对寄主作物造成危害,使列当的防除成为一个世界性难题。本文详述了列当的生活史、为害现状以及防除措施,并突出了生物防除的生态效益与经济效益。基于"诱捕"作物及"捕获"作物诱导列当种子"自杀发芽"理论的防除机制,本文提出了新型可持续生态防除思想,为列当科杂草防除提供参考。Orobanche spp.can produce a large number of small seeds,which are easily spread by agricultural implements or animals.It has caused severe harm to host plants before emerging to ground.Controlling root parasitic weed Orobanche becomes a worldwide problem.This paper introduced life cycle of Orobanche,harm status and control measures.It highlighted the ecological and economic benefits of biological control.Based on ＂trap crop＂ and ＂catch crop＂ methods for stimulating Orobanche seeds germination,a new way of eliminating the seed bank within the infested soil for the weeds ＂suicidal germination＂ was pointed out.A novel sustaining way for controlling Orobanche weeds was also described.
