| 中文摘要: |
| 过16种植物提取物对油茶林昆虫进行诱捕，筛选出2种对油茶害虫引诱效果较好的植物提取物，并在油茶林进行引诱效果及诱集昆虫种群动态的研究。结果表明，2016年4月-8月的引诱试验中，共诱集到昆虫7 455头。其中油茶叶片水提粗提物诱集到昆虫数量最多，达4 368头，诱虫谱较广，诱集到23种昆虫，可以诱集为害油茶林的害虫主要有假眼小绿叶蝉、琼凹大叶蝉、大青叶蝉、白痣广翅蜡蝉、茶角胸叶甲等; 其次为油茶乙醇粗提物，诱集到2 078头昆虫，且对八点广翅蜡蝉、小蠹类害虫的诱捕效果最佳。植物提取物作为引诱剂，可为油茶林害虫的发生期、发生量的监测预报提供直接的、客观的依据。 |
| 英文摘要: |
| 16 kinds of plant extracts were used to trap the pests of Camellia oleifera, among them, Water extracts and ethanol extracts from C.oleifera had the good attractant effect. Furthermore, the attractant effect and the pest population dynamics of C.oleifera trapped by the water and ethanol extracts from plant were investigated in the field. The results showed that a total of 7 455 individuals of insects were captured from April to August in 2016. C.oleifera leaf extract could trap the largest number of insects, up to 4 368 individuals, and the attractant spectrum of C.oleifera leaf extract was wider, with 23 species. The main trapped insect pests included Empoasca vitis (Gthe), Bothrogonia qiongana Yang & Li, Cicadella viridis (Linnaeus), Ricanula sublimata Jacobi, Basilepta melanopus Lefevre. C.oleifera leaf ethanol extract ranked the second place, which trapped 2 078 individuals of insects. It had the best trapping effect on Ricania speculum (Walker) and Scolytidae insects. Thus, plant extracts could be recommended to be used as a lure for monitoring and forecasting of insect pests in C.oleifera. |
