Sesane oil killed only 2 percent of the houseflies tested; pyre- 
thrins plus this oil killed 57 percent; pyrethrins plus factions I 
end II of the oil killed 100 and 91 percent, respectively; pyrethrins 
plus sesemin (crystalline fraction) and the noncrystalline residue 
killed 85 and 89 percent, respectively; therefore, the sesarain isolated 
from the sesame oil increased the toxicity of pyrethrum to flies.—
