In one observation of 100 grapes which had "been sprayed with 
nicotine, only 8 to 13 were infested with the eggs of vine moths, 
whereas the authors counted as many as 168 eggs on 100 grapes which 
had not "been treated. Nicotine acted, therefore, as a repellent to 
the moths and deterred oviposition. 
TThen grape vines were sprayed with a mixture, consisting of 
1.33 kg. nicotine per 100 1. bordeaux solution, practically all of 
the eggs failed to hatch.
