FACTBOX-Mexico energy reform debate

Sept 1 (Reuters) - Latest developments as Mexico's ruling conservatives court opposition lawmakers to approve an energy reform to allow more private investment in the state-controlled oil industry in hope of bolstering falling output.

Compiled from Reuters stories, Mexican newspaper reports, television and radio.

* Former leftist presidential candidate Andres Manuel Lopez Obrador told his followers to be ready to launch street protests if lawmakers moved to approve President Felipe Calderon's energy reform proposal, Milenio newspaper reported.

* Calderon urged Congress in a televised speech to approve his proposal, which is aimed at shoring up flagging production and reserves.

* Calderon proposes to let state energy monopoly Pemex sweeten oil field service contracts with private companies using performance-based bonuses. Left-wingers say that would violate a ban on private companies exploring for and producing oil in Mexico.

* Mexico's Congress began holding sessions on Monday after a summer break and is expected to approve an energy reform in the coming months. (Reporting by Miguel Angel Gutierrez)
