Medicinal plante Borazambol with the scientific name of Perovskia abrotanoides Karel. belongs to the family Lamiaceae. It is growing wild in the margin of mountainous roads of arid and cold climate of north Iran. It is for a long time that indigenous people by different methods in traditional medicine use its products in preventing and curing diseases. In this research, essential oils of Perovs...

The chemical composition of volatile oils from 22 genotypes of Citrus and related genera was poorly differentiated, but chemometric techniques have clarified the relationships between the 22 genotypes, and allowed us to understand their resistance to D. citri. The most convincing similarities include the synthesis of (Z)-β-ocimene and (E)-caryophyllene for all 11 genotypes of group A. Genotypes...

Fresh leaves, stems and roots of Cachrys cristata, were subjected to hydrodistillation and the oils obtained were analyzed by means of GC and GC-MS. Sixty eight constituents were in total identified, with (Z)β-ocimene (44.2% and 30.5%) dominating in leaves and stems oils, while the major metabolite of the roots was found to be p-tolualdehyde (39.6%), followed by (Z)-β-ocimene (15.2%). The micro...

This in vitro study aimed at estimating the disappearance rates of 14 terpenes and terpenoids after 24-h incubation with mixed bacteria from caprine rumens. These compounds comprised nine monoterpene hydrocarbons (δ-3-carene, p-cymene, β-myrcene, (E)- and (Z)-β-ocimene, α-phellandrene, α-terpinene, γ-terpinene and α-terpinolene), four oxygenated monoterpenes ((E)- and (Z)-linalool oxide, 4-terp...

β-Ocimene is a very common plant volatile released in important amounts from the leaves and flowers of many plant species. This acyclic monoterpene can play several biological functions in plants, by potentially affecting floral visitors and also by mediating defensive responses to herbivory. The ubiquity and high relative abundance of β-ocimene in the floral scents of species from most plant f...

In this paper we report on the large induction of volatile organic compounds (VOCs) from a single leaf of the mossy sorrel, Rumex confertus Willd. (Polygonaceae), by herbivory of the red dock weevil (Apion miniatum Germ., Coleoptera: Apionidae). VOC blends induced by the red dock weevil herbivory included 5 green leaf volatiles (GLVs) ((Z)-3-hexenal, (E)-2-hexenal, (Z)-3-hexenol, (E)-2-hexenol,...

Studies were conducted to assess glacial acetic acid (GAA) with various host plant volatiles (HPVs) and the sex pheromone, (E,E)-8, 10-dodecadien-1-ol, of codling moth, Cydia pomonella (L), as lures in traps for tortricid pests that often co-occur in tree fruits in the western United States. In addition to codling moth, field trapping studies were conducted with oriental fruit moth, Grapholita ...

Cooperative brood care is diagnostic of animal societies. This is particularly true for the advanced social insects, and the honey bee is the best understood of the insect societies. A brood pheromone signaling the presence of larvae in a bee colony has been characterised and well studied, but here we explored whether honey bee larvae actively signal their food needs pheromonally to workers. We...
