NICOTINE AS AN INSECTICIDE. 



(1) Nicotine spray solutions do not pass into the tracheae, 

 nor do they penetrate the integuments of insects. 



(2) The fumes from nicotine used as a fumigant, the vapors 

 from nicotine spray solutions, and the odoriferous particles from 

 evaporated nicotine spray solutions or from powdered tobacco 

 pass into the tracheae and are widely distributed to all the tissues. 



(3) Regardless of how it is applied, whenever nicotine kills 

 insects, as well as all other animals, it kills by paralysis, which 

 in insects travels along the ventral nerve cord from the abdomen 

 to the brain. 



(4) The writer does not know just how nicotine paralyzes 

 the nervous system, but he does know that it prevents the nerve 

 cells from functioning, and that in regard to the simplest animals 

 its presence around the cells causes the same structural changes 

 resulting in death as observed when other animals of the same 

 kind are deprived of oxygen. In such cases it seems to kill 

 physically rather than chemically, but the evidence presented 

 does not conclusively prove this view. — Exchange.
