Glucosinolate hydrolysis products suppress entomopathogenic nematodes <scp> <i>in vitro</i> </scp> but do not protect sequestering flea beetle larvae <scp> <i>in vivo</i> </scp>
Although glucosinolate hydrolysis products are toxic to EPNs and their symbiotic bacteria, they did not protect P. armoraciae larvae from EPN infection. However, the larval food plant influenced EPN susceptibility and bacterial community composition, highlighting the role of host plant traits in shaping insect-EPN interactions. These findings provide new insights into the limitations of EPN-based biocontrol against glucosinolate-sequestering pests. © 2026 The Author(s).
