THE British Field Sports Society has recently issued a booklet entitled "Report on the Biology and Control of the Heather Beetle". In view of the damage caused by this insect in the past, this report and its findings will be of very definite interest to those who are concerned with the management and preservation of moorlands. These include not only the moor owner and his shooting tenants, but also the sheep grazier and, to a lesser degree, the bee-keeper. The activities of this beetle deplete the numbers of grouse, impoverish the grazing and decrease the honey-flow. The report under notice is based upon investigations carried out between 1937 and 1940 under the direction and supervision of Dr. A. E. Cameron, of the Department of Agriculture and Forest Zoology, University of Edinburgh.
