LABORATORY STUDY ON THE LONG-TERM REPELLENCY OF DILL SEED EXTRACT TO CONFUSED FLOUR BEETLES1
LABORATORY STUDY ON THE LONG-TERM REPELLENCY OF DILL SEED EXTRACT TO CONFUSED FLOUR BEETLES1
Page Range: 70 – 72
Dill seed extract has strong and persistent repellency to confused flour beetle, Tribolium confusum Jacquelin du Val. Laboratory evaluation of repellency by the treated paper method at concentrations of 680 to 85 μg/cm2 was continued for two years. The repellency decreased at a faster rate up to 5 mo, then slowed down gradually. After two years, still over 50% of the original repellency remained at treating concentrations of 680, 340, and 170 μg/cm2, and about 35% for the 85 μg/cm2 concentration.
