Spectral Response Characteristics of the Boll Weevil1

Abstract
A Y-tube test chamber was used in group-response studies with adult boll weevils, Anthonomus grandis Boheman, to determine the relative attractiveness of equal energy, narrow-band stimuli in the spectral region from 315 to 665 mμ Maximum response was obtained for wavelengths in the blue-green (490 to 515 mμ) region of the spectrum with decreased response indicated for both shorter and longer wavelengths.
