( $\beta$-polytype of InSe single crystals of p- and n-type are intercalated with Ba and Li by electrochemical process. This compound shows to be a good host for the insertion of Ba or Li atours at room temperature. The temperature dependence of the resistivity in the temperature range 4.2 < T < 300 K and the magnetoresistance at T = 4.2 K are investigated. Electrical transport measurements on Ba or Li intercalated n-InSe and p-InSe show a decrease for n-InSe and an increase for p-InSe of the resistivity with respect to non-intercalated samples. Weak localization was observed in the host n-InSe samples.
