Description	We construct Feynman rules and Supergraphs in SIM(2) superspace. To test our methods we perform a one-loop calculation of the effective action of the SIM(2) supersymmetric-Wess-Zumino model including a term which explicitly breaks Lorentz invariance. The renormalization of the model is also discussed.
