Attraction of cabbage stem flea beetle ( <scp> <i>Psylliodes chrysocephala</i> </scp> ) to host plant odors

This research provides insights into the olfactory behavior of CSFB and, to our knowledge, is the first to show behavioral responses of adult CSFB towards host plant volatiles in olfactometer tests. Interestingly, only females responded to VOCs, suggesting sexual dimorphism in olfactory sensitivity during this life stage. These findings may help to lay the groundwork for further studies aimed at improving pest management strategies in OSR cultivation. © 2025 The Author(s).
