Chemical constituents of the essential oil of flowers of Lavandula officinalis Chaix. growing in Isfahan, Iran, were studied by TLC and gas chromatography-mass specrtometery (GC-MS) methods. Twelve components which constitute 94.8% of the examined oil were identified. The main constituents were linalool (34.1%), 1,8-cineole (18.5%), borneol (14.5%), camphor (10.2%), terpinen-4-ol (4.5%), l...

Nineteen host plant volatiles (HPVs) were screened for attractivity to adult codling moth Cydia pomonella (L.) as a fourth component of core blends (3K) including (E,Z)-2,4-ethyl decadienoate, (E)-4,8-dimethyl-1,3,7-nonatriene and acetic acid. Each new quaternary combination was compared with previously reported attractive bisexual lure (4K), consisting the 3K blend plus 6-ethenyl-2,2,6-trimeth...

Several plant species defend themselves indirectly from herbivores by producing herbivore-induced volatile compounds that attract the natural enemies of herbivores. Here we tested the effects of elevated atmospheric CO(2) (720 micromol mol(-1)) concentration on this indirect defense, physiological properties, and constitutive and induced emissions of white cabbage (Brassica oleracea ssp. capita...
