Two experiments were carried out during the two successive seasons 2006/2007&2007/2008 at El-Santa district ,Gharbia Governorate to evaluate the efficiency of five materials (Actellic,Caple (2), Garlic oil, Mint oil, and Castor oil) against Thrips tabaci It was obviousthat the toxicity of Actellic, Caple (2) and Garlic oil were closely subsequent population reduction of 88.8%,82.4% and 75.8% were superior respectively. Mint oil and Castor oil showed a moderate toxicity to the population of T. tabaci they caused 67.4% and 58.7% population reduction respectively. These results concluded  that successful control of T. Tabaci  can be achieved by using Actellic,Caple(2)and Garlic oil at the rates of 2.5cm3/L.water ,10cm3/L.water and0.2cm3/L.water respectively.
