When<jats:italic>Drosophila<\/jats:italic>larvae encounter a noxious thermal, chemical, or mechanical stimulus, they perform a stereotyped rolling behavior. These noxious stimuli are detected by polymodal nociceptor neurons that tile the larval epidermis. Although several types of sensory neurons feed into the nociceptive behavioral output, the highly branched class IV multidendritic arborization neurons are the most critical. At the molecular level,<jats:italic>Drosophila<\/jats:italic>nociception shares many conserved features with vertebrate nociception, making it a useful organism for medically relevant research in this area. Here, we review three larval assays for nociceptive behavior using mechanical stimuli, optogenetic activation, and the naturalistic stimuli of parasitoid wasp attacks. Together, the assays described have been successfully used by many laboratories in studies of the molecular, cellular, and circuit mechanisms of nociception. In addition, the simple nature of the assays we describe can be useful in teaching laboratories for undergraduate students.<\/jats:p>","DOI":"10.1101\/pdb.top108172","type":"journal-article","created":{"date-parts":[[2024,8,2]],"date-time":"2024-08-02T15:05:36Z","timestamp":1722611136000},"page":"pdb.top108172","source":"Crossref","is-referenced-by-count":2,"title":["Nociception in<i>Drosophila<\/i>Larvae"],"prefix":"10.1101","volume":"2025","author":[{"given":"Lydia J.","family":"Borjon","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephanie E.","family":"Mauthner","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"W.
