The importance of chamomile (Chamomilla recutita) inflorescence is widely known in classical and folk medicine, with the largest group its effective constituents forming essential oil (chamazulene, a-bisabolol, α-farnesene, trans-β-farnesene, spathulenol, cis/trans-en-in-dicycloethers). Among cultivated species, Hungarian BK-2 contains more chamazulene than German Degumil type, which mainly for...

Background Anthriscus caucalis is a non-native plant in North America with invasive potential. As part of our interests essential oils the Great Basin, wild-growing sample A. was collected southwestern Idaho. Methods The obtained by hydrodistillation and analyzed gas chromatographic methods (GC–MS, GC–FID, chiral GC–MS). Results major components oil were cis-chrysanthenyl acetate (42.3%), myrce...

The effect of four temperatures (18, 20, 25 and 30°C) on pupa development and sexual maturity of Anastrepha obliqua adults was investigated under laboratory conditions. The results showed that the duration of the pupal stage decreased with an increase in temperature (29, 25, 13 and 12 days, respectively), and maintaining the pupae at 18°C and 20°C results in a low percentage of pupation, pupa w...

BACKGROUND The fire ant, Solenopsis invicta, is one of the most aggressive and invasive species in the world. The trail pheromone Z,E-α-farnesene (91% purity) was prepared, and disruption of worker trail orientation was tested using an ethanol-based aerosol formulation presenting a single puff of this compound by airbrush and compressed air. Trail-following behaviour was recorded by overhead we...

Mushrooms are believed to have a great potential for production of bioactive metabolites e. g. terpenes, a group of interesting compounds with diverse chemical properties such as antitumour and antibacterial activity. Cop6 is a terpene cyclase isolated from the mushroom Coprinus cinereus that catalyzes the cyclization of farnesyl diphosphate (FPP) to mainly αcuprenene. In this study gas chromat...

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...
