A Honey Bee (Apis mellifera) Light Phase Response Curve

A phase response curve for individual honey bees shows a maximum advance and delay of 1.5 hours.

• The phase response curve (PRC) is classified as a weak (Type 1) response.
• Light pulses of 1000 lux were used in the study involving 134 honey bees.
• The maximum advance occurs between circadian times (CT) 18 and 3.
• The maximum delay occurs between CT 12 and 18.
• This is the first documented light PRC for honey bees, providing valuable information for researchers.
