PROPRIETARY insecticides made from lonchocarpus 
J. D. Smith (384), American Commercial Attache a.t Lima, Peru, 
on May 21, 1934, advised that "Cubex" is an insecticide made from 
Peruvian cube by Piaggio and Turpino at Lima, Peru. Clark (82), Assistant 
Trade Commissioner at Lima, Peru, in 1937 reported that the cube used 
in manufacturing Cubex is sold by W. R. Grace and Company who bring it 
from Iquitos to Lima. According to Crilloy (108), more Cubex was sold 
in 1936 than previously. Greenup (175), American Commercial Attache at 
Lima, Peru, in 1937 advised that Cubex is used only as a general house- 
hold insecticide for killing flies, etc., but it is understood that the 
manufacturer is planning to make a compound for agricultural purposes. 
Fisher and Bailey (149) in 1937 published a compilation of in- 
formation on commercial insecticides. Products made from cube include 
Pyrote made by the Mechling Bros. Chemical Co., Camden, N. J., and Ro-Tone 
made by the Lucas Kil-Tone Co. , Vineland, N. J.
