Observations of individual moth responses were combined to determine the most stimulating band, the effect of temperature, and effects of species, sex, time of testing, and moth origin.

No definite effects of temperature, sex, time of testing, or moth origin were found. The tomato hornworm moth was definitely the less active species and showed a greater difference between bands of maximum and minimum reactions.
