Abstract
In lab-experiment lasted from March 2015 to January 2016 to declare the effect of static magnetism on the biology and potentiality to compact the phytophagous mites Tetranychus urticae (Tetranychidae), a total numbers of 2410 mite individuals (with 3 replicates), were reared on plant discs (caster bean) under laboratory temperature. Discs were dipped on 6 treatments of solutions as the following: 1-Distilled water, (control or check), (w). 2- magnetized distilled water (W+mag). 3- Sea water(s), 4- magnetized sea water (S+mag). 5- Vertimec solution (the recommended acaricide), (V) and 6- magnetized vertimec solution (V+mag). Investigation and recording results was carried out 1,3 and 5 days after treatments. Results reported that there was a clear and significant effect for the magnetism to kill and minimize mite populations. Reduction percentages show that magnetized distilled water led to reduction 42.29%, while the normal sea water (S) recorded 46.66% and the magnetized sea water (S+mag) raised to 68.13%. This means it was nearby value to the vertimec acaricide, which recorded 84.59%, and increased to 86.63% with the magnetic field. Results indicated that magnetic treatments with sea water significantly minimized the laid eggs as the distilled water (W) recorded 59.68 eggs/disc, which was decreased to 20, 7.91 eggs/disc for the treatments of sea water (S) and magnetized sea water (S+ mag) respectively, that makes this treatments (S+ mag) is promising in the control programs of mites and being a safe acaricide alternative.
