Responses of the Crucifer Flea Beetle to Brassica Volatiles in an Olfactometer

open access: yesEnvironmental Entomology, 2009
A suite of commercially available volatile compounds was tested in an olfactometer bioassay for responses by the crucifer flea beetle (Phyllotreta cruciferae). Flea beetles were inhibited by exposure to hexane, pentane, and ethanol. Allyl-isothiocyanate,

Bed bug preferences for host odor or aggregation odor are differentially modulated by physiological state in various odorscapes

open access: yesPest Management Science, Volume 82, Issue 2, Page 1426-1436, February 2026.
The bed bug olfactory system is highly tuned to two odor sources with dedicated odor information‐processing pathways that are modulated by the satiety–hunger state. Understanding the dynamic nature of switching odor preferences at different phases of blood digestion will contribute to the development of lures with host kairomones and aggregation ...
