LABORATORY EVALUATION OF DILL SEED EXTRACT IN REDUCING INFESTATION OF RICE WEEVIL IN STORED WHEAT1
LABORATORY EVALUATION OF DILL SEED EXTRACT IN REDUCING INFESTATION OF RICE WEEVIL IN STORED WHEAT1
Page Range: 317 – 320
Wheat was surface-treated with acetone extract of dill seed and exposed to rice weevils, Sitophilus oryzae (L.). At 2000 ppm, dill extract provided complete protection 1-day after treatment, and still provided 68.13% reduction of the F1 generation after treated wheat was stored for 52 weeks. One day after treatment, dosages of 1000 and 500 ppm reduced the F1 generation 81.86 and 21.99%, respectively, and the effect decreased rapidly.
