Common bean (Phaseolus vulgaris L.) is one of the most important and widely cultivated Legume in the world. The two-spotted spider mite (TTSM), is one of the most important agricultural pests. This research provided some evidence of the applicability of CuO nano particles and nano capsule for controlling TTSM. To evaluate the effect of copper nano-capsules on the populations of TSSM from red beans, Akhtar variety was used. This bean is a susceptible variety. To evaluate the effect of copper nano-capsules on the populations of TSSM from red beans, Akhtar variety was used. This bean is a susceptible variety. Five experiments were carried out, including spraying with copper nanocapsule (Cu2O) at 5 levels of concentration (1) without nano-capsule copper (2) nanocapsules 1 g / l (3) nano capsules 2.5 g / l (4) nano capsules 4 Grams per liter 5. Nanocapsule was 5.5 grams per liter. The time of spraying was the simultaneous appearance of the first flower buds in each plant. According to the results, the use of copper nanocapsules has a significant effect on decreasing population of the pest. This can be different by change the concentration of nanocapsules. Copper oxide nanoparticles were first synthesized via a fast precipitation method. The prepared products were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Fourier transform infrared (FT-IR) spectroscopy.
