Nanopesticides plays so important rule to control pests with highly efficacy in comparable with other patterns of pesticides. Formation depending on redispersible powder comprising nanoparticles of Cypermethrin. LC50’s were 1.99 and 1.05 ppm of nano- Cypermethrin against Aphis gossypii (Glover) and Tetranychus urticae Koch. resp., while normal Cypermethrin LC50’s recorded 82.14 and 60.12 ppm, resp., of both pests. Moreover, nano- Cypermethrin had so long residual effect, even it caused mortality up to 40% after twenty days of treatment. Data recommended use of nanopesticides as a new trend to get good results of pests’ control.
