Soybean saponin and its calcium salt showed high toxicity to Sitophilus oryzae (L.). Saponin, an active component of soybeans, gave a high degree of protection to wheat that was dusted at 300 ppm. Dosages of 600 to 5000 ppm showed increases in effectiveness. A dosage of 600 ppm produced 100% mortality within I week. A dosage of 150 ppm was less effective hut still toxic to the insects. The calcium salt was slightly less toxic to the insects than was the saponin. Soybean meal and defatted soybeans also gave protection to wheat when dusted at the higher dosage levels tested.
