        原标题:密密麻麻!西双版纳发现蝗虫入侵,灾受灾面积达1214亩

        据云南省林业和草原局7月10日报告显示,自6月28日普洱市江城县牛倮河保护区与老挝接壤的边界沿线发现黄脊竹蝗入侵灾害,后普洱市宁洱县、西双版纳傣族自治州勐腊县局部区域也发生危害。

        人民日报记者从勐腊县农业农村局了解到,截至7月10日,勐腊县累计发生黄脊竹蝗灾害面积1214亩,其中农地634亩,林地580亩,主要发生区域为勐腊县勐伴镇、瑶区乡、易武镇。

        截至10日,西双版纳州勐腊县开展防治防控面积累计1745亩,无人机飞防作业累计6架次。目前西双版纳州已经成立了黄脊竹蝗灾害防治指挥部,对黄脊竹蝗防治工作安排了专项资金,开展了技术培训,三县市所有边境乡镇都已安排了防蝗观测点。

        据了解,6月29日,勐腊县勐伴镇回落村委会回龙小组玉米地发现黄脊竹蝗,勐腊县农业农村局接到勐伴镇电话报告后,派出技术人员及时到现场查看。经过调查发现,勐伴镇的黄脊竹蝗是由去年老挝迁飞过来的成虫产卵孵化而成,为境内虫源,主要危害对象为竹子、芭蕉、粽叶芦等植物。勐腊县农业农村局接报后迅速组织人员赴勐伴镇开展防治指导。

        此外,7月10日下午17:30,在勐腊县易武镇与江城县整董镇接壤的大龙山、蚕豆田监测到少量黄脊竹蝗迁飞入境,具体面积正在核实中。

        此前报道:

        云南省林业和草原局7月10日对外通报,目前黄脊竹蝗灾害仍处于可控范围。但专家分析,云南省边境一线7月至8月份黄脊竹蝗爆发成灾的可能性大。

        通报显示,截至7月7日,黄脊竹蝗累计发生面积81193亩,其中,中度2000亩、重度(成灾)1000亩。主要危害对象为竹子、芭蕉、粽叶芦等植物。

        发现黄脊竹蝗从老挝迁飞入境以来,省、市、县林草部门即组织多架次的无人机选用环境友好型的药剂对入侵的黄脊竹蝗进行了阻截防控。目前,黄脊竹蝗灾害处于可控范围 。

        截至7月7日,有关部门共调集植保无人机组21组,累计开展飞防作业498架次,投入地面喷雾机械138台套,出动车辆233辆次,防治面积24671亩,创建防控隔离带30公里。

        云南省林业和草原局及时召集相关部门研究部署防控工作,并派出相关人员及技术专家赶赴现场指导普洱市开展防控工作,要求普洱市各县(区)外防输入、内防扩散,务必全面做好监测并控制住黄脊竹蝗灾情蔓延势头,充分调动生态护林员、森林资源管护员参与黄脊竹蝗监测预警工作,建立省、市、县、乡、村、组、公益林管护员虫情监测网络,全面排查蝗灾隐患,突出区域治理和科学防控。落实24小时值班制度、实行零报告和日报告制度,全面准确掌握黄脊竹蝗发生情况。采取无人机防治与地面防治、化学防治与生物防治相结合的措施进行防治。

        据云南省林业和草原科学院研究员分析,目前境外黄脊竹蝗持续入侵态势严重,并有向周边县区蔓延趋势,云南边境一线7月至8月份黄脊竹蝗爆发成灾的可能性大。

        下一步,省林草部门将加强与我国山水相连的老挝等国的沟通协调,对入侵云南的黄脊竹蝗虫源地进行防控,并做好国内国外虫情测报,形成长效机制,根据虫情预测预报结果,采用绿色综合防控技术对黄脊竹蝗虫进行分类治理,防早防小,确保全省森林资源、粮食生产安全。

        黄脊竹蝗在我国长江之南多数竹子种植区都有分布,竹蝗大发生时,可将竹叶全部吃光,是我国竹子的重要害虫之一。这次云南普洱边境等地的黄脊竹蝗灾害是当地种群与外迁种群的双重叠加,尤其是边境线以南国外种群暴发成灾,由于边境线以南当地食料缺乏,黄脊竹蝗成虫羽化后开始不断迁飞入侵普洱江城等周边县区,对我省竹林造成严重威胁。

        黄脊竹蝗生物学特性

        黄脊竹蝗在云南普洱、版纳等地1年发生1代。

        4月中旬至5月底孵化,6月下旬为盛孵期。

        6月下旬成虫羽化,7月初为羽化盛期,成虫取食后约20天交尾产卵。跳蝻4龄至成虫交尾前食量最大(约占竹蝗总食量的60%以上),危害最烈。

        7月中旬至8月为产卵盛期。成虫产卵期1~2个月,寿命50~80天。成虫在近交尾时常成群迁飞转移,使发生区域迅速扩大。

        交尾后不再迁移,选择向阳的山腰、杂草灌木较少、竹林较稀、土壤较疏松的地方聚集产卵。
