Abstract
SUMMARY: It is estimated that, in England and Wales, about 162,000 acres of DDT‐setisitive barley cultivars have been grown annually in recent years under conditions where leatherjacket damage may occur. But, on average, economic damage only seems likely to occur on about 5,000 acres of DDT‐sensitive barley. About 160,000 acres of non‐sensitive cultivars are also grown under conditions where leatherjacket damage may occur, as well as a considerable acreage of wheat and oats. From limited knowledge about leatherjacket population distribution it seems unlikely that damaging populations occur on more than about 25,000 acres of cereals overall. It seems possible that about 300,000 acres of grassland may support populations in excess of 500,000 leatherjacket larvae per acre in an average year, though the economic damage done cannot be assessed at present.Established, and possible alternative, chemical control methods are discussed.
