Tobacco dust is far more efficient than 40-percent nicotine sul- 
phate in controlling the raspberry crown borer (penni setia ma rginata 
Harr.). Tobacco dust (100 mesh) rras sifted on the hill and covered 
thinly with soil; then 1 gal. water was poured on.

A mixture, consisting of 2 lb. Paris green, 3 lb. whale- 
oil soap, 25 oz. nicotine sulphate, and 100 gal. water, was 
sprayed on cabbage plants in Hawaii. It completely wiped out 
the plant lice and several species of lepidopterous larvae on 
the leaves, but it was ineffective against the well-protected 
Hellula larvae.
