These insects attack cacao on the west coast of Africa. Nicoti 
sulphate has proved the most satisfactory insecticide; it is more ef- 
ficient as a spray than as a dust. The formula recommended is 6 gal. 
water boiled with 1/4 lb. hard soap or double that amount of soft soap 
to which, when boiling, 1 oz. 40 percent nicotine sulphate is added. A 
gallon of spray will cover approximately 10 to 12 trees averaging 5 ft 
in height and 30 to 40 leaves on each tree.

The control measure recommended is spraying the trees with 3 oz. 
nicotine (96 - 98 percent) and 4 lb. soft soap in 40 gal. water. Dustira 
with nicotine has also proved satisfactory, but the same precautions 
should be taken to prevent the return of the insects that fall to the 
ground unharmed.
