A combination of solbar (barium polyaulfide) and anabasine 
sulfate oan be used for the simultaneous destruction of ououmber 
mildew and aphida. {These materials will react to form barium 
sulfate, free anabasine, and free sulfur.-- R. C. R.] A solution 
containing 0.5 percent of green soap and 0*3 percent of anabasine 
sulfate killed all the aphids.— Zubov and Vasilevskii (87).

Concentration-mortality curves are given for solutions of various 
nitrogenous bases and soap -when applied to the eggs of Lygaeus kgja&j 
Stal, and the data are analysed statistically. The following median 
lethal concentrations were obtained: Niootine 0.11, quinoline 0.12, 
anabasine 0.18, piperidine 0.29, pyridine 19.6, and sodium oleate 2.0 
percent. Quinoline was the only compound that killed the eggs at 
once. The others permitted development of the embryos to continue 
for several days. In some cases the young bugs were able to emerge 
from the eggs but died soon after hatching.— C. F. Smith ( 72) «

Of the stomaoh larvioides tested on Luoilia ouprina WLed. in 
Australia, anabasine sulfate (40 peroent anabasine ) was toxic at 
0.1 percent concentration, whereas nicotine sulfate was toxic at 
0.01 percent.— Lennox ( 38) . 
In tests by P. M. Petrov of sprays against ( Mayetiola ) Fhytophaga 
destructor (Say), preparations of anabasine gave the best results ana 
were effective against the eggs.— Ostapets (49). 
The effects of aerosols of anabasine sulfate and anabasine on 
Anopheles mosquitoes were investigated. The mosquitoes were very 
sensitive to anabasine solutions. The minimum lethal dose was 0.2 
gnu of anabasine per cubic meter. The aerosol possesses an un- 
pleasant odor, producing coughing, but under summer conditions it 
is dispersed rapidly and no odor remains after 15-20 minutes. To 
accelerate the fraction at low temperatures the mixture must be 
heated or some 4sy lime and uulfurio acid added. Anabasine may be 
volatilised by adding the free base or the sulfate to sand heated 
to 300-350 *• The aerosol had no harmful effect on rabbits and hens, 
on the germinating properties of seeds, or on food produote.— 
Pogodina and Sokolov (53). 
The toxioity of anabasine to mosquito larvae was much inferior 
to that of niootine.— Freak (23). 
The toxioity indioes of anabasine sulfate (35 peroent anabasine) 
to Drosophila ampelophila Loew were determined in three kinds of baits 
as follows t In apple sirup 14.0, in molasses 7.2, and in oane sugar 
and glycerin 30.7. Sodium arsenite in the respective baits gives the 
following indioest 78.6, 62.8, and 63,7.— Patterson (50).
