Dynamic Headspace Analysis of Floral Volatiles: A Comparison of Methods
Oikos, 1998Lack of standardization of floral scent analysis using dynamic headspace collection and GC-MS has prevented meaningful biological comparisons of results from different studies. We explored technique-related sources of variation by comparing the relative performances of different trapping sorbents, elution solvents and vacuum pump flow rates in the ...

Host selection by thrips is affected by the floral volatile profile of sunflower
Plant, Cell & EnvironmentAbstractThrips, Frankliniella intonsa, is a highly polyphagous pest with a worldwide distribution. F. intonsa‐infested sunflower seeds show marked visual damage. The study findings revealed that significantly more F. intonsa infested confection sunflower compared to oilseed sunflower, via olfactometer bioassay studies, we found that compared with the ...

Chemical diversity of floral volatiles in Asclepiadoideae-Asclepiadeae (Apocynaceae)
Biochemical Systematics and Ecology, 2008Abstract Floral volatiles of 15 plant species from 8 genera ( Cynanchum , Funastrum , Gonolobus , Metastelma , Oxypetalum , Orthosia , Sarcostemma , and Vincetoxicum ) of the Apocynaceae-Asclepiadoideae tribe Asclepiadeae were investigated to get a better understanding of the odor chemistry, and of the role of odors in pollinator attraction ...

Floral Volatiles ofElaeagnus umbellataThunb.
Journal of Essential Oil Research, 1995ABSTRACT The floral volatiles of Elaeagnus umbellata Thunb. (autumn olive) were isolated by simultaneous steam distillation/extraction and “purge and trap” techniques. Extracts were analyzed by GC/M S. In the steam distillate, 84 peaks were detected of which 56 were assigned structures.

Trapping noctuid moths with synthetic floral volatile lures
Entomologia Experimentalis et Applicata, 2002AbstractMale and female noctuid moths were collected from plastic bucket traps that were baited with different synthetic floral chemicals and placed in peanut fields. Traps baited with phenylacetaldehyde, benzyl acetate, and a blend of phenylacetaldehyde, benzyl acetate, and benzaldehyde collected more soybean looper moths, Pseudoplusia includens ...
