Detection and deactivation of pheromone and plant odor components by the beet armyworm, Spodoptera exigua (Hübner) (Lepidoptera: Noctuidae)

Electroantennogram responses of an invasive species fall webworm (Hyphantria cunea) to host volatile compounds

“…Many studies have indicated that olfactory reactions of male insects can be heavily affected by leaf volatiles [5,6,15,33]. When combined, botanical secondary substances and sex pheromones could attract Helicoverpa armigera moths over large distances [34].…”

“…For example, one of the most common green leaf volatiles, (Z)-3-hexene acetate, can enhance the effects of sex pheromones in Helicoverpa zea [4] and Heliothis virescens [5]. Similarly, blending green leaf volatiles with sex pheromones of Cydia pomonella resulted in more male moths being caught compared with controls of only sex pheromone compounds [6].…”

Electrophysiological studies of olfaction in the whip spider Phrynus parvulus (Arachnida, Amblypygi)

“…As with many insects (for example, Dickens et al, 1993;Chinta et al, 1994;Thiery and Marion-Poll, 1998), P. parvulus responds to a number of six-carbon-atom compounds which are common components of green leaf odor, but the strongest responses were those to a number of phenolic compounds. The amblypygids are generalist predators and are found in association with a wide variety of trees, and we believe that none of the compounds producing large ELG responses is likely to have specific importance to the animals in the field (E. A. Hebets, unpublished observations).…”

“…Most studies of insect olfaction have focused on responses to highly specific stimuli such as pheromones or host odors (Dickens et al, 1993;Bartelt et al, 1995;Chambers et al, 1996;Raguso et al, 1996;Honda et al, 1998;Zhu et al, 1999). The specificity of responses to particular odors such as pheromones has been well documented in insects and has led to a more general understanding of sensory detection and processing.…”

Considerations on Static and Dynamic Sorptive and Adsorptive Sampling to Monitor Volatiles Emitted by Living Plants

“…Additionally, the time window between 13 and 17 min contains several unidentified peaks which are typical for Tenax and are not present in the PDMS profile. The Tenax background thus hampers accurate quantification of two important flavor compounds, namely benzaldehyde and acetophenone which moreover possess biological activity as attractants for insects [31][32][33][34]. In fact, benzaldehyde was also identified in the PDMS trace applying ion extraction at m/z 106 but its concentration was ten times lower than in the case of Tenax sampling (insert Figure 5).…”
