摘要
[目的]进行棕榈红棕象甲形态的观察及发生为害情况调查。[方法]从南宁市苗圃采回红棕象甲各虫态的标本,在实体显微镜下进行形态观察,并把特征加以描述。在南宁市以棕榈科植物为调查对象,在红棕象甲为害高峰期进行随机取样调查,记录调查总株数、被害株数。[结果]红棕象甲不同个体成虫前胸背板的液滴状斑大小、形状和排列不一致,不同寄主幼虫形态特征相同,但同龄幼虫的虫体大小却不一样。红棕象甲在南宁市内主要分布于部分苗圃和棕榈科植物集中种植地,而且在南宁市范围内主要为害国王椰、老人葵、加拿利海枣、霸王棕、美丽针葵等棕榈科植物。[结论]该研究结果为南宁市棕榈红棕象甲发生规律和防治技术研究奠定了基础。
[Objective]The study aimed to conduct the observation on the morphology of Rhynhophorus ferrugineus Fabricius and investigation on its occurrence damage.[Method]The various insect state samples of Rhynhophorus ferrugineus Fabricius were selected from the plant nursery,and were made for the morphology observation under the entity microscope,and then their characteristics were described.In Nanning City,with the Palmae plant as the investigation object,the random sampling investigation was conducted when the damage of Rhynhophorus ferrugineus Fabricius was in the peak period and the total plant number and the harmed plant number were investigated by the record method.[Result]The pronotum of different individual adult of Rhynhophorus ferrugineus Fabricius was inconsistent on droplet-shaped spot size,shape and arrangement.The morphological characteristics of different host larvae were same,but the different larvae were not same on the insect size.Rhynhophorus ferrugineus Fabricius in Nanning city was mainly distributed in the part of the nursery and the centralized planting land of Palmae plants and mainly harmed the Palmae plants such as King coconut,Washingtonia filifera,Phoenix canariensis,Overlord Brown,Beautiful needle sunflower in Nanning City.[Conclusion]The study laid the foundation for the research on the occurrence law and the control technique of Rhynhophorus ferrugineus Fabricius in Nanning City.
