摘要:

At the B.R.A. Conference on Bee Flower Relationships, Dr. Mary Percival was asked to speak on the mutual adaptation of bees and flowers. She confessed that the preparation of her lecture was one of the toughest assignments she had ever been given—because it is extremely difficult to make sure that what looks like adaptation really is adaptation. The issue is always obscured by the fact that many bees, especially honeybees, are great opportunists, and will exploit many different sources of food.Dr. Percival's lecture, which is printed here, will upset some of the current ideas on the close interadaptation of bees and flowers, and we hope that it will set readers thinking afresh on the relationships between their bees and the flowers which give them their harvest.

摘要:

At the B.R.A. Conference on Bee-Flower Relationships last July, Mr. D. W. Way gave details of some work on fruit pollination at East Malling Research Station, and Mr. R. P. Hawkins discussed one of the many problems of seed production which have been studied at the National Institute of Agricultural Botany in Cambridge. Mr. Hawkins' report emphasized the need for more observations on bumble bees in England, and we hope that its publication here may stimulate further interest in studying their distribution and behaviour.

摘要:

More and more research workers are using techniques which enable them to rear honeybees in the laboratory, outside the hive, and to carry out experiments on them under controlled conditions. This is adding greatly to our knowledge of the characteristics and behaviour of eggs, larvae and pupae. In the course of Dr. Cameron Jay's studies at Rothamsted Experimental Station on the development of the honeybee, he recorded observations on the appearance of pupae. These observations have much wider applications than his own experiments, and will be useful to beekeepers as well as to research workers.Dr. Jay is now Assistant Professor of Entomology in the University of Manitoba in Canada.

摘要:

In some countries bee venom has been in regular use for many years for the treatment of certain forms of rheumatism and arthritis, whereas in others it is disregarded, or regarded as a‘crank’treatment which orthodox medical practitioners should have nothing to do with.In this complex subject, any advance which enables more exact observations to be made is welcome. Charles Mraz, a well-known American beekeeper who has worked with bee venom since 1935, has now made progress in standardizing bee venom solutions. Details of this test—which will probably become known as the‘Mraz test for bee venom’—are being published at an early stage so that others can try it out and report on it.
