一般描述

反式-β-法尼烯是蚜虫物种中警报信息素的主要活性成分。它会引起一些行为反应,比如踢打、停止进食、移开或者下降等。

应用

本分析标准品还可用于:

  • 采用气相色谱-质谱联用技术(GC-MS)对属于21个不同大麻品系的82株植物部位进行次生代谢物分析,包括甾醇和萜类化合物(单萜、倍半萜和三萜),同时使用高效液相色谱(HPLC)结合紫外和质谱联用(UV-MS)对黄酮类化合物进行次生代谢物分析。
  • 通过气相色谱法结合质谱(MS)和火焰离子化检测(FID)法,测定香樟叶和花精油样品中163种化合物的含量
  • 通过GC-FID和GC-MS法对从C. macropodum枯叶枯花甲醇提取物中的精油样品同时测定49种化合物的含量
  • 采用固相微萃取(SPME)技术中DVB/CAR/PDMS纤维对P. Nobby’s Pacific Sunset花朵中31种挥发性有机化合物进行样品浓缩,然后再通过GC-MS分析法对其进行测定和定量分析

Pyrethrum extract from dry flowers of Tanacetum cinerariifolium (formally Chrysanthemum cinerariifolium) has been used globally as a popular insect repellent against arthropod pests for thousands of years. However, the mechanistic basis of pyrethrum repellency remains unknown. In this study, we

Aphids are agricultural pests of great economical interest. Alternatives to insecticides, using semiochemicals, are of difficult applications. In fact, sex pheromones are of little use as aphids reproduce partenogenetically most of the time. Besides, the alarm pheromone, (E)-ß-farnesene for a

Plants can respond physiologically to damaging ultraviolet-B radiation by altering leaf chemistry, especially UV absorbing phenolic compounds. However, the effects on terpene emissions have received little attention. We conducted two field trials in plots with supplemented UV-B radiation and assessed

When aphids are attacked by natural enemies, they emit alarm pheromone to alert conspecifics. For most aphids tested, (E)-beta-farnesene (EBF) is the main, or only, constituent of the alarm pheromone. In response to alarm pheromone, alerted aphids drop off the

Odorant-binding proteins (OBPs) are important parts of insect olfactory systems, and sensitive olfaction is vital for phytophagous insects in host foraging. Electrophysiological studies are helpful in understanding olfactory sensing in Sitobion avenae (Hemiptera: Aphididae), but the functions of odorant-binding proteins
