Abstract

SUMMARYFour methods of confining colonies of honeybees for up to 12 hours (with and without water) were tested: (1) black or white-painted polythene sheeting, (2) wet or dry burlap (jute sacking), (3) entrance screen, (4) chipped ice over the hive entrance. Colony temperatures and reactions were nearest to normal when wet burlap or ice was used. In 1960, when external air temperatures reached about 36°C., all colonies beneath plastic were killed, as well as one with an entrance screen.
