The behavioral and electrophysiological responses of the obliquebanded leafroller, Choristoneura rosaceana (Harris), and the redbanded leafroller, Argyrotaenia velutinana (Walker), to crude extracts of Arctium lappa, Bifora radians, Humulus lupulus, Xanthium strumarium, and Verbascum spp. were studied under laboratory conditions. Plant materials were dried and ground before extraction with meth...

This study evaluates the content of essential oils (EOs) and prenylated flavonoid Xanthohumol (XN) in extracts Slovenian hops, cultivar Aurora, obtained by using fluids different polarity. It is a continuation our previous work, investigating extraction bitter acids from hops. Extraction was conducted semi-continuously, sub- supercritical polarity, i.e., carbon dioxide (CO2) propane as non-pola...

Humulus lupulus is a dioecious twining herb, with an outstanding vertical development capacity. Hop plants are usually grown on trellises up to 4.5 6.0 m high, whose management requires intense use of water, fertilizers, pesticides, and labor. In semiarid Mediterranean areas, where native resources often scarce, the adoption low-trellis farming systems could be sustainable option for hop cultiv...
