THE REPELLANCY EFFECT OF POWDER OF MANY PLANTS ON RED FLOUR BEETLES TRIBOLIUM CASTANIUM

Abstract

The aim of this study is investigated the repellent effect of powder of four plants : Borago efficinalis ; Mentha piperta ;Officinalis anisum; Eucaluptus glubulus against the red flour beetles Tribolium castanium. The repellency effect determained in three increasing concentrations (5,10,15)%(w/w) for all investigated powder plant in 48 hr . The results appeared that M. piperta was most repellent efficiency plant in value (26,43,76.6)% in concentration (5,10,15)%(w/w) respectively then O. anisum (10,23.3,60)%; E. glubulus (10,23,53)%, B. efficinalis (6.6,23,43)% also this study appeared the efficacy repellency of the plant against red flour beetles increasing with increase the concentration of powder's plant and exposure time.
