Description

Experimental protocol to test for circadian rhythmicity in photoperiodic responses by exposing insects to constant day length (12h) with varying night lengths to create non-24h photoperiods, then measuring diapause induction rates.

Typical Equipment

  • temperature-controlled chambers
  • white fluorescent lamps
  • light microscope

Output Measurements

  • female diapause proportions
  • photoperiodic response curves
