Excerpt from Field Experiments for the Control of Cabbage Insects The effectiveness of the materials was rated by recording the live loopers on four to five plants per plot, 4 to 5 days after each application. Percent reduction was calculated on the basis of the infestation in the treated as compared with that in the check plots. On the last examination the mature heads plus the outer leaves were removed and each leaf was examined for insects. At each examination the loopers were classified on the basis of size; small included newly hatched larvae up to one-half inch in length; medium, one-half to 1 inch; and large, 1 inch or longer. Pupae were included with the large larvae. An aphid colony ranged from 1 to 100 or more aphids. The possible phytotoxic effect of the materials on the plants was also noted.
