Due to its importance, the phenomenon of hydrogen
bonding has been the subject of much research over the
years. Among the different techniques used to study
hydrogen bonded systems, vibrational spectroscopy is
perhaps the most sensitive because of the striking
changes induced in molecular spectra by the formation of
hydrogen...
The toxicity of menthol, menthone, pulegone, limonene, and a-pinene, five monoterpenes found in peppermint (Mentha piperita L.), to the variegated cutworm (Peridroma saucia Hiibner) was characterized by in vivo and in vitro methods. Pulegone and menthone caused slower growth over six days when incorporated into an artificial diet and fed...

The Miridae, or plant bugs, associated with noble fir, Abies
procera Rehd., are discussed. Thirty six species of the Miridae were
collected from noble fir. Twenty five of these species are considered
only "visitors" to noble fir. The study does not deal with these
species. Noble fir is a host...
