The temperature dependence of electrical resistivity was measured in the si
ngle crystals of LaTe2 (#5, #6), CeTe2 (#2, #5). PrTe2, GdTe2 and polycryst
alline SmTe2 for I//ab-plane and I//c -axis. It shows a strong anisotropy.
In stoichiometric CeTe2, especially, the metal-insulator transition is obse
rved at about 150 K and the anomalies due to the competition between the ca
rrier concentrations and the scattering rate are also found at 5.8 and 3 K.
