ABSTRACT
Repelling effects of peach plant L. (Rosales: Rosaceae), Eucalyptus, L. (Myrtales: Myrtaceae), Ashok, (Magnoliids: Annonaceae), Milk thistle, (Asterales: Asteraceae), and Sow thistle, (Asterales: Asteraceae) extracts each in petroleum ether, acetone and ethanol were evaluated at the concentration of 1000, 500 and 250 ppm against cotton mealy bug ( ) in a free choice bioassay for two weeks. The ethanol extract of was the most effective against cotton mealy bug having highest repellency (72.5%) at 500 ppm dose. The lowest average repellency (26.3 %) was observed in acetone extract of at 500 ppm dose.
