摘要
豆大蓟马(Megalurothrips usitatus)是豇豆(Vigna unguiculata)的重要害虫之一,为实现对其绿色可持续性防控,对豆大蓟马的发生与危害、生物学特性、抗药性和防治等方面进行了综述。豆大蓟马主要通过在豇豆果实内部产卵和取食幼嫩组织汁液为害。海南省的环境条件十分适宜豆大蓟马的生长和繁殖,而豆大蓟马因其虫体小、传播速度快、隐蔽性高、繁殖能力强等特点在海南极易大面积暴发。近年来,化学农药的滥用和不合理使用使海南省不同地方的豆大蓟马种群对常规杀虫剂产生了极高的抗药性,这进一步加重了该害虫的灾变,同时带来了农药残留、环境污染等诸多问题。对豆大蓟马的防治主要包括农业防治、理化诱控、化学防治和生物防治等,在田间生产实践中,宜采用多种方法,对其进行综合防治。
Megalurothrips usitatus is one of the main pests of cowpea in Hainan Province.It infests cowpea mainly by laying eggs in cowpea and feeding on flowers and pods,which seriously affects the quality and yield of cowpea.Hainan Province is located in the tropics,and its unique environmental conditions are very suitable for the growth and reproduction of thrips.Thrips are small in size,fast in transmission,high in concealment and strong in reproductive ability,and its outbreak easily occurs,causing huge economic losses.In recent years the abuse and irrational use of chemical insecticides resulted in high resistance of M.usitatus populations to conventional insecticides in different areas of Hainan province,which further aggravated the infestation of this insect pest and brought up many risks including insecticide residues and environmental pollution.In order to achieve green sustainable management of this insect pest,the ecological mechanism for the outbreak of M.usitatus was reviewed and discussed in terms of occurrence and damages,biological characteristics and insecticide resistances.The current domestic and overseas research progress of the integrated control of this pest was reviewed.This review might provide reference for control and prevention of M.usitatus in the field.
