A host-derived volatile primes context-dependent foraging behavior in parasitic nematodes via a lysosome-associated neural pathway

Proceedings of the National Academy of Sciences, Volume 123, Issue 8, February 2026. <br/>SignificanceParasites use chemical signals from their hosts to locate suitable targets, yet how such signals modify parasite behavior remains unclear. Here, we show that a volatile released by a host insect quantitatively alters how a parasitic nematode …
