and 1-500), yet in no experiment was there a sufficient number of eggs 
killed to warrant the statement that this material might kill eggs. It 
was thought, when the material was used, that it might act as a stom¬ 
ach poison and kill the larva as it ate (apparently) its way out of the 
shell, but as pointed out before the larva probably does not consume 
any considerable portion of the shell as it breaks through with its 
mandibles. Nicotine resinate has good lasting qualities and is not 
readily decomposed after spraying, consequently, any larva which 
consumes its shell would suffer if nicotine resinate were present.
