摘 要 【目的】 明确番茄潜叶蛾Tuta absoluta在山东地区的地理分布、在温室大棚内番茄不同种植模式下(茬口)的种群动态和不同防治技术的控害效率,为番茄潜叶蛾的综合防治提供科学依据。【方法】 在山东省选取17个调查监测点,利用性诱剂监测番茄潜叶蛾潜在分布区,并在番茄集约化种植的平度市系统监测番茄潜叶蛾在不同防治技术控害效率下的种群动态。【结果】 在17个监测点中,有9个监测点监测到番茄潜叶蛾发生,主要集中在潍坊、淄博、聊城和青岛等番茄种植面积较多的地区。山东地区温室大棚番茄种植模式主要分为越冬长茬、冬春茬和秋冬茬3种,在越冬长茬和秋冬茬模式下,10月初至12月底番茄潜叶蛾发生量较少,为害较轻,每2周诱蛾量在5头以下;在越冬长茬和冬春茬模式下,1月上旬至2月底番茄潜叶蛾发生量较少,每2周诱蛾量低于5头,3-6月为主要发生期,每2周诱蛾量达30头以上。覆盖防虫网能降低番茄潜叶蛾的成虫数量和被害株率,被害株率最高降低57.1%;迷向技术可有效降低番茄潜叶蛾的种群数量及其为害程度,防治效率在60%以上。【结论】 番茄种植集中的地区推广秋冬茬种植,减轻番茄潜叶蛾对番茄的为害;防虫网能够有效降低番茄潜叶蛾的成虫数量和番茄被害株率,被害株率最高降低57.1%;迷向技术的使用使温室被害株率显著下降,防治效果在60%以上可作为防治的关键技术。
英文摘要:
Abstract [Aim] To clarify the geographic distribution of Tuta absoluta in Shandong Province, to monitor its population dynamics in greenhouses under different planting patterns (crop rotations), and to evaluate the efficacy of different control methods for this pest. [Methods] The distribution of T. absoluta was determined using sex pheromone traps deployed at seventeen sites across Shandong Province. In addition, systematic monitoring of its population dynamics was conducted in Pingdu City, an area of intensive tomato cultivation. [Results] T. absoluta was detected at 9 of the 17 survey sites, primarily in regions with intensive tomato cultivation such as Weifang, Zibo, Liaocheng and Qingdao. Based on local differences in tomato cultivation in greenhouses, tomato planting systems can be categorized into overwintering (OW), winter-spring (WS), and autumn-winter (AW), planting. In the OW and SA systems, there was minimal occurrence of T. absoluta from early October to late November, and a relatively low percentage of damaged tomatoes in December. In these planting systems, the number of moths captured every two weeks was consistently below five. In the OW crop and AW planting systems, T. absoluta numbers were low from early January to late February, with less than 5 moths captured every two weeks. The peak of occurrence in these planting systems was from March to June, with more than 30 moths captured every two weeks. Covering tomato plants with insect-proof nets significantly reduced the adult population and the reduced the proportion of damaged plants by up to 57.1%. The efficacy of orientation-based techniques in pest control exceeds 60%, effectively reducing the population size and impact of invasive species. [Conclusion] T. absoluta could rapidly become a serious pest in Shandong Province. It is crucial, therefore, to effectively monitor the occurrence of this pest in different areas in order to facilitate effective, integrated, pest management.
