SPRING NUMBER 13 
by an application of parrafin and an iron hoop around the bottom 
have been very satisfactory and have the advantage of being 
easily transported. 
A dust of calcium cyanide has been successfully used under 
tents. If, however, too large a dosage is used or the humidity is 
high, burning may result. Experiments are now in progress, in 
cooperation with the American Cyanamid Company, to test out 
the practicability of killing scale insects as well as aphids by this 
method. Nicotine sulphate dusts can be safely used in any 
weather and are effective except during a rain or cold, cloudy 
weather. An exposure of from one to five minutes is sufficient, 
half a day does no harm. These dusts will also kill rust mites 
and scale crawlers. Red spiders require a longer exposure. Lady 
beetles in all stages and syrphus fly larvae usually go thru with- 
out injury.
