In the laboratory all larvae of the apple moth Hyponomeuta 
padellus L. ( malinellu s Zell.) fed on leaves sprayed with tobacco 
decoction died within 9 days, unless they were about to pupate. Spray- 
. ing an infested tree with a decoction of 1 lb. of tobacco dust in 3 gal. 
of water did not affect the larvae while they remained in the mines in 
the leaves, but killed 81.2 percent shortly after they came to the sur- 
face and began feeding on the sprayed foliage; after a. fortnight all had 
apparently ~been killed, as no nests were formed on the tree. Prom these 
tests, the author concludes that nicotine acts as a stomach poison as 
well. as a contact insecticide.

Sprays of 1 per mille nicotine sulphate and 5 per mille soft 
soap killed 85.8 percent of the larvae, the mortality increasing to 
95.9 percent when double the amount of soap was used. Nicotine and 
soap in the se.me concentrations killed 96.9 and 98.2 percent respectively 
These were tests against the third instar larvae. Sprays consisting of 
1 per mille nicotine sulphate and 10 per mille soap killed 89.3 percent 
of the fourth-ins tar larvae.

Of various sprays, nicotine, either alone or with alcohol or in 
bordeaux mixture, gave the best results against Hyponomeut a padellus L. 
TTxiile other formulae had greater powers of wetting and penetrating the 
nests a bordeaux and nicotine spray besides possessing distinctly toxic 
properties gave surer results, while casein or ox-gall is a good spreader.

Against Nygnia phaeorrhoea Don. and Hyponomeuta padellus malinell- 
us Zell., the most satisfactory results were obtained with nicotine 
sprays with the addition of soap, which sometimes killed all larvae of
