Abstract: In this study, the effect of Fungatol and Gamma-T-ol extracted from Melaleuca alternifolia (Maiden and Betche) Cheel (Myrtaceae) on Aphis gossypii Glover and Tetranychus urticae Koch was determined using leaf dipping method. In laboratory tests, the leaf discs (50 mm diameter) taken from bean (Phaseolus vulgaris L.) and eggplant (Solanum melongena L.) and were dipped in five different concentrations of Fungatol (1.25, 1.90, 2.20, 2.50 and 3.50%) and Gamma-T-ol (0.25, 0.50, 1.00, 1.50 and 3.60%) for 5 s. The tests were repeated five times. Mortality was recorded after 1, 24, 48 h in tests with A. gossypii adult females and after 1, 24, 48, 72h in tests with T. urticae adult females. After 1, 24 and 48 h, the highest concentrations of Fungatol (3.50%) and Gamma-T-ol (3.60%) had caused 0, 18, 42% and 0, 20, 48.9% mortality of A. gossypii, respectively. After 1, 24, 48 and 72 h the same concentrations of these extracts had caused 0, 52, 74, 94% and 0, 52, 78, 93.3% mortality of T. urticae adult females, respectively. The results showed that Fungatol and Gamma-T-ol extracts offer good potential to be used to control A. gossypii and T. urticae. Their use in pest management could be considered after validation in the field.
