Pluronic F-127 is a non-toxic and thermoreversible transparent copolymer that allows nematodes to
move freely inside the gel and be observed under a microscope. Pluronic gel has previously been shown
to be a useful medium for three dimensional study of plant parasitic nematode host-finding behavior, but
not for host-habitat finding of entomopathogenic nematodes (EPNs). In the current study, we used
Pluronic gel for the first time to investigate the
