本文结合秦岭地区板栗淡娇异蝽的发生情况、主要特性,分析了该虫害防控有待提升的环节,并提出了针对性的防控策略。研究区板栗产业快速发展并形成完整产业链,而淡娇异蝽的广泛分布制约了其进一步发展;该害虫每年发生1代,若虫共5龄,5月下旬至6月上旬成虫羽化,羽化后交配并产卵于板栗枝干或落叶中,其发生速度快,主要为害板栗的幼嫩组织,导致受害的嫩枝生长受阻,严重时枝条干枯死亡,其发生受到环境、寄主植物和天敌的影响。当前该虫害防控体系在监测预警体系、防治手段、农户认知水平和防治能力、综合防治技术衔接与整合方面有待进一步提升。本文提出建立监测网络、引入性诱剂等监测技术,结合物联网等现代信息技术,建立监测信息共享平台;及时清理果园内枯枝落叶等供淡娇异蝽越冬的场所,选择黑光灯诱杀等物理措施与苏云金芽孢杆菌等生物农药进行防治;开展技术培训班,通过发放宣传资料等方式加强宣传引导;优化生物、物理和农业防治等多种防治技术组合,在主产区建立示范基地等防控策略。本文为研究区板栗产业的可持续发展和害虫综合治理提供参考。

This study based on the occurrence status and key biological characteristics of Urostylis yangi on Castanea mollissima in the Qinling Mountains, analyzing the aspects requiring improvement in the prevention and control of this pest and proposing targeted prevention and control strategies. The Castanea mollissima industry in the study area has developed rapidly and formed a complete industrial chain, while the widespread distribution of Urostylis yangi has restricted its further development. The pest has one generation per year with 5 instars of nymphs. Adults emerge from late May to early June, and mating and oviposition on the branches or fallen leaves of Castanea mollissima occur after emergence. This pest has a rapid population growth rate and mainly infests the tender tissues of Castanea mollissima, resulting in inhibited growth of the damaged shoots and even withering and death of branches in severe cases. The occurrence of Urostylis yangi is affected by environmental conditions, host plants and natural enemies. At present, the existing prevention and control system of the pest still had room for improvement in terms of monitoring and early warning systems, control methods, farmers’ cognitive level and control capability, as well as the connection and integration of integrated control technologies. Corresponding strategies were put forward as follows: establishing a monitoring network, introducing monitoring technologies such as sex pheromones, integrating modern information technologies including the Internet of Things (IoT) to build a monitoring information sharing platform; timely cleaning of overwintering sites for Urostylis yangi such as withered branches and fallen leaves in orchards, and the selection of physical measures (e.g., black light trap trapping) and biological pesticides (e.g., Bacillus thuringiensis) for control, constitute an integrated and environmentally friendly pest management strategy; organizing technical training courses and strengthening publicity and guidance by distributing promotional materials; optimizing the combination of multiple control technologies including biological, physical and agricultural measures, and establishing demonstration bases in major producing areas. This study provides a reference for the sustainable development of the Castanea mollissima industry and the integrated pest management (IPM) in the study area.
