Extract

Timing traps are widely used to study the diurnal flight activity of insects, their response rhythms to physical and chemical (olfactory) stimuli, and the effect of weather factors on these behaviors. Goetz (1941) used an adhesive-coated horizontal metal disk driven by a mechanical clock to determine the periodicity of male-female attraction in two lepidopterous species on grapes. The area of the disk exposed at any time corresponded to a 1-h sector of the clock dial. The disk completed a full revolution every 12 h and therefore the trap had to be checked twice a day. Also, since the clock speed was not variable, the trapping interval could only be adjusted by decreasing or increasing the opening to the sticky disk.
