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

Optimisation of alginate formulations is described in order to develop semiochemical (E-β-farnesene and E-β-caryophyllene) slow-release devices in biological control approaches by attracting predators and parasitoids of aphids. Various formulation criteria were optimised with respect to semiochemical encapsulation capacity. Moreover, the

In most aphid species, facultative parthenogenetic reproduction allows rapid growth and formation of large single-genotype colonies. Upon predator attack, individual aphids emit an alarm pheromone to warn the colony of this danger. (E)-beta-farnesene (EBF) is the predominant constituent of the

(E)-β-farnesene is a strong and efficient alarm pheromone in most aphid species. However, applications in agriculture are prevented by its relatively high volatility, its susceptibility to oxidation and its complex and expensive synthesis. To develop novel compounds for aphid control

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
