Abstract
Laboratory tests with a number of insecticides indicated that gamma B.H.C. at low dilutions caused heavy mortality in the laboratory. An indication that mortality was due to the vapour phase of gamma B.H.C. was obtained. In field tests, gamma B.H.C. caused high mortality in ova collected shortly after spraying, but not in ova collected eight days later,whilst D.D.T., dieldrin and pyrethrum had no effect. It is concluded that the prospect of controlling ematocerus through the ova or the newly hatched larvae is not promising.
