浏阳实蝇种群发生动态监测及防控技术

Study on Dynamic Monitoring and Control Technology of Fruit Fly Species in Liuyang

为查明实蝇在湖南省浏阳市的发生规律和对寄主作物为害情况,指导当地蔬菜和水果等作物的实蝇防治工作。于2015—2018年系统调查了实蝇在浏阳市的种群分布情况与发生为害规律。调查结果表明:浏阳市发生为害的实蝇种群主要有瓜实蝇 Bactrocera cucurbitae(Coquillett)、南瓜实蝇 Bactrocera(Zeugodacus)tau(Walker)、具条实蝇 Bactrocera(Zeugodacus) scutellata(Hendel)、三点棍腹实蝇 Dacus(Callantra)trimacula(Wang)、桔大实蝇 Bactrocera(Tetradacus)citri(Chen)和桔小实蝇Bactrocera(Bactrocere)dorsalis(Hendel)等6个种类,其中以南瓜实蝇发生量较大,为害作物品种较多;其次是具条实蝇和桔小实蝇。从监测年份来看,实蝇发生呈现逐年递增趋势,有加重为害作物的梯度。为严密防止实蝇害虫的入侵和扩散,有效控制实蝇为害,提出了坚持"三防、三治"的防治策略以及加强植保专业队伍建设和运用物联网技术等综合配套防控措施。

In order to find out the occurrence regularity and damage to host crops of fruit flies in Liuyang City,Hunan Province,and guide the prevention and control of fruit flies in local vegetables and fruits,the population distribution and damage regularity of fruit flies in Liuyang City were systematically investigated from 2015 to 2018.The results show that Bactrocera cucurbitae(Coquillett),Bactrocera(Zeugodacus)tau(Walker),Bactrocera(Zeugodacus)scutellata(Hendel),Dacus(Callantra)trimacula(Wang),Bactrocera(Tetradacus)citri(Chen)and Bactrocera(Bactrocere)dorsalis(Hendel)occurred in Liuyang City.Among them,the occurrence of Bactrocera(Zeugodacus)tau(Walker)is large,and it damages more crop varieties;the second are Bactrocera(Zeugodacus)scutellata(Hendel)and Bactrocera(Bactrocere)dorsalis(Hendel).From the monitoring years,the occurrence of fruit flies showed an increasing trend year by year,with a gradient of aggravating the damage to crops.In order to strictly prevent the invasion and spread of fruit flies and effectively control the damage of fruit flies,the comprehensive control measures were put forward,such as adhering to the"three prevention,three treatment"control strategy,strengthening the construction of plant protection professional team and using the Internet of things technology.
