| Abstract | ||||
| Two experiments were carried out to study the effects of magnetic force and magnetic water on two spotted spider mites Tetranychus urticae (Koch) (Acari: Tetranychidae) and Esuseis scutalis (El-Badry) (Acari: Phytoseiidae) .In the first experiment leaflets of infested soybean with T. urticae and E. scutalis were passed through different concentrations of magnetic force and magnetic water at different time intervals the concen-trations of magnetic force and magnetic water in the laboratorywere 100, 200, 300, 400 and 500 Gausses, respectively, while Magnetic force and magnetic waterin the field were1000, 2000, 3000, 4000 and 5000 Gausses, respectively. The second experiment was conducted by sprayed the infested leaflets to T. urticae and E. scutalis at three time intervals. The results in both experiments revealed thatthe numbers of two tested mites were reduced after treated with magnetic force or magnetic water. Also, the data indicated that magnetic force wasthe most effect on adults and the eggs stage of T. urticae, but was the least effective on E. scutalis, while magnetic water was moderate effect on eggs and adults of two tested mites. Under the field condition the magnetic force was the most effect on behavior and population of T. urticae andE. scutalis, while magnetic water was moderate effect on the population and behavior of eggs and motile stages to T. urticae and adults of E. scutalis | ||||
