蛾类花香型广谱引诱剂配方的均匀设计

为了明确花香成分间的相互作用，探讨适宜的蛾类花香型引诱剂筛选方法，以夜蛾和螟蛾为主要靶标，采用配方均匀设计组配了一系列花香型引诱剂配方，并进行了田间诱捕试验。结果表明，供试花香型引诱剂可大量引诱棉铃虫、银纹夜蛾、白条银纹夜蛾、甜菜夜蛾、甜菜白带螟、亚洲玉米螟、稻纵卷叶螟和豇豆荚螟等多种重要蛾类害虫。在花香成分中，苯乙醛、乙酸苯甲酯和水杨醛是3种最为关键的广谱诱蛾活性成分，而2种侧链最短的芳香物质苯甲醛和苯甲醇则对诱蛾效果具有普遍的负面影响。因此，选用重要蛾类共同偏好的花香气味开发广谱引诱剂，可以简化蛾类的诱控防治技术。

Optimization of Floral Attractant Formula with Broad-trapping Spectrum of Moths Using Uniform Design

In order to define the interaction between floral compositions and study the appropriate screening methods of floral attractants trapping moths, the authors mixed a list of floral attractant formulas using formula uniform design and conducted field trapping for noctuids and pyralids as the main target. The results showed that the selected floral attractants could mass trap a variety of important moth pests including Helicoverpa armigera, Argyrogramma agnate, A. albostriata, Spodoptera exigua, Hymenia recurvalis, Ostrinia furnacalis, Cnaphalocrocis medinalis and Maruca testulalis, etc. Among floral compositions, phenylacetaldehyde, benzyl acetate and salicylaldehyde were three key active compositions with wide-trapping moths, however, two aromatic compounds with the shortest side chain, benaldehyde and benzyl alcohol, exhibited generic negative effects on trapping moths. Therefore, developed wide-trapping attractant using floral scents preferred collectively by important moths can simplify trapping and control techniques of moths.
