The United States Department of Agriculture, Bureau of Entomology and 
Plant Quarantine (442), in 1936 reported that in the fall of 1935 several 
species of cutworms were destructive to cabbage in several plantings at 
Charleston, S. C., but the derris dusts used wore not effective against 
these noctuids. 
The Louisiana Agricultural Experiment Station (258) in 1938 published 
a summary of entomological progress in that State, in which C. E. Smith 
reported that against larvae of Agrotinae, the true cutworms, the inorganic 
materials (paris green, calcium arsenate, and cryolite) were superior to 
the organic materials (derris and pyre thrum powders). 
At a meeting of the North Central States Entomologists ( 509 ) in 1938, 
W. H. V.hite remarked that cube and derris do not control the Agrotinae.
