摘要
甜菜夜蛾在我国原本是一种间歇性暴发为害的农业植物害虫,近年来已演变成大部分地区蔬菜和棉花等作物上常发性害虫。甜菜夜蛾在我国广大地区发生为害呈现出明显的为害程度加重、为害区域扩大、南方为害世代多于北方、南方为害时期早于北方的特点。为害种群呈现出明显的接力棒式关系,表现出典型的迁飞为害特征。根据这一特点,提出了加强甜菜夜蛾迁飞虫源监测、建立异地预测预报技术,集成以生态调控和生物防治为主的多种防治措施相协调的综合防治技术体系,并在全国范围内建立核心示范区,推广、带动、辐射周边地区统防统治,从而实现对甜菜夜蛾的可持续治理。
Spodoptera exigua,was originally an intermittent outbreak of agricultural plant pests in China.In recent years,it has evolved into a common pest on the vegetables and cottons.Its outbreak in China presents obvious increasing tendency with wide distribution,and outbreak generations in Southern part of China is more than those in Northern part of China,while annual damage time is earlier than that of Northern part of China,displaying an obvious baton-relation with migratory damaging trait.According to this,this article proposes a sustainable management for this important pest by strengthening migratory pest source monitoring,integrating multiple control measures mainly including ecological regulation and biological control,constructing nuclear example areas which can extend and eradiate related control measures to other place.
