Chemical constituents of Raphanus sativus Linn. roots were extracted and tested for their toxicity
against adults and second instar nymphs of A. gossypii under laboratory conditions. The most effective
fraction against both adults and nymphs was methylene chloride fraction with LC50 values of 386.63 and
309.43 ppm, followed by ethyl acetate fraction with LC50 values of 394.9 and 334.37 ppm then petroleum
ether fraction with LC50 values of 636.2 and 424.56 ppm, for adults and nymphs, respectively. Also, the
volatile components of each fraction were qualitatively and quantitatively identified and characterized by
GC/MS technique. Moreover, the impact of the sub-lethal concentrations of R. sativus roots extracts on
transaminases and alkaline phosphatase of A. gossypii was studied. Great inhibition of all tested enzymes
activity was observed. This suggested the high potency of R. sativus roots extracts as environmentally
friendly alternatives of traditional insecticides.
