The {\em cutting and sewing} procedure is used for getting two-loop orderFeynman diagrams of $\Phi^{4}$-theory with an internal SU(N) symmetry group,starting from tachyon amplitudes of the open bosonic string theory. In asuitably defined field theory limit, we reproduce the field theory amplitudesproperly normalized and expressed in the Schwinger parametrization
