This study aimed to evaluate the unused part of the tomato plant leaves, as a botanical pesticide. The cotton aphid, Aphis gossypii Glover (Hemiptera: Aphididae) is one of the most serious pest all over the world. They have a wide host range, and may transmit pathogenic virus. It attacks tomato leaves and sucks the plant sap from the leaves by its piercing and sucking mouth parts. Due to the problems of chemical pesticides to all organisms and environment, natural control replaced pesticides. Tomato extract contains many contents of phenolic and flavonoid compounds which were effective in control. Different little concentrations of tomato extract were applied in control of aphid and caused high mortality proportion. In the present study, the concentrations used were 250, 500, 750 and 1000 ppm and the mortality increased when the concentrations increased, which was 27.5 % with 250 ppm and reached 80% with 1000 ppm. Also, the chemical composition of extract of tomato (Lycopersicon spp.), was characterized by GC/ MS analysis which revealed the presence of 46 compounds, the major compound was Phytol (16.03%).
