Flight Activity of Honeybees in a Flight and Rearing Room.: II. The Influence of Constant and Cycling Temperatures

Abstract

Honeybee colonies were held in a flight room under constant and cycling temperatures. Flight activity, as measured by entrance counts, increased wi environmental temperature, and closely followed changes in it. In July-August, flight activity was nearly twice as great at 32° as at 21°; in April and November it was nearly three times as great. Bimodal patterns in daily flight cycles were observed. More winter bees than summer bees flew at lower temperatures, but fewer at higher temperatures.
