Mutant flies show a deficit in gustatory aversion to 6mM camphor in a two way-choice test. Camphor-induced action potentials in S6 taste sensilla are greatly reduced in the mutant flies compared to wild type.
Mutant flies show normal olfactory avoidance of 6mM camphor in a direct airborne repellent test.
The normal preference of third instar larvae for 17.5[o]C over 14[o]C in a two-way choice test is eliminated in trplMB03075 and trpl302/trplMB03075 larvae.
