wtrw1 mutant adults show normal preference for less solid sucrose-agarose food than a harder one (higher agarose conc., same sucrose content) one in a two-way food choice assay.
The gustatory aversion of mutant flies to 6mM camphor in a two way-choice test is not significantly different from that seen in wild-type flies.
wtrw1 mutants retain a preference for 18[o]C (i.e. are thermotactic).
