Extract

Some of the results of an attempt to apply ecological principles in the solution of apple insect control problems in Nova Scotia have been given in previous papers by Pickett et al. (1946), Lord (1947, 1949), Pickett (1952), and MacPhee (1952). Briefly, these studies aim at an understanding of the changes in the interrelations of the species in an orcl-lard when spray materials are added to the environment. The emphasis to date has heen placed on the effects of spray chemicals on the populations of entomophagous species. The results of this work have already had a marked effect on orchard insect control practices in Nova Scotia.
