Article Synopsis
  • * A detailed protocol is provided for conducting single sensillum recordings from SLF labial ORNs to assess their sensitivity, specificity, and response patterns to different odors.
  • * The protocol includes steps for preparing odorant cartridges, setting up equipment, and analyzing the resulting neuronal data, with further information referenced from Dweck and Claire.

Deciphering how spotted lanternfly (SLF), an invasive polyphagous planthopper in North America, engages with its environment is a pressing issue with fundamental biological significance and economic importance. This interaction primarily depends on olfaction. However, the cellular basis of olfaction in SLF remains elusive.

Insects taste the external world through taste hairs, or sensilla, that have pores at their tips. When a sensillum comes into contact with a potential food source, compounds from the food source enter through the pore and activate neurons within. For over 50 years, these responses have been recorded using a technique called tip recording.

Taste systems encode chemical cues that drive vital behaviors. We have elucidated noncanonical features of taste coding using an unconventional kind of electrophysiological analysis. We find that taste neurons of are much more sensitive than previously thought.
