Laboratory experiments were conducted under controlled conditions to test the insecticidal activity of aqueous and organic extract of different solvents ethanol, acetone and hexane from three plants collected from north- Sinai Tree tobacco, Nicotiana glauca G.; Chinaberry, Melia azedarach L. and Lemon, Citrus limon L. against the adult stage of Rust-Red Flour Beetle, Tribolium castaneum H. The results showed that the aqueous extract of N. glauca gave the highest toxicity among the other tested plants with LD5 equal to .86 x 5 ppm using ethanol solvent. However, the organic extracts of M. azedarach L. showed the best result with LD5 equal to .2 x 5 ppm. On the other hand, both the aqueous and organic extracts of N. glauca gave the highest toxicity with LD5's of .6 x 5 ppm and .66 x 5 ppm, respectively, with acetone solvent. But using hexane solvent, aqueous extract of C. limon L. was obviously the most toxic extract compared to the aqueous extracts of the tested plants with LD5 .86 x 5 ppm and in the organic phase N. glauca gave the best result with LD5 equal to .7 x 5 ppm .
