THE pea moth, Laspeyresia nigricana, Steph., is a widely distributed pest of garden and field peas in Great Britain and central and southern Europe, While in North America it has spread to all main pea-growing areas. In England the most severe losses occur in the pea-producing counties of Lincoln, Essex and Kent. D. W. Wright and Q. A. Geering, of the Horticultural Research Station and School of Agriculture, Cambridge, have published a useful paper on the biology and control of the pea moth (Bull. Entom. Res., 39, pt. 1, 57 ; 1948).
