Abstract
Particle production from vacuum fluctuations during inflation is briefly revisited. The moduli problem occurring
with light particles produced at the end of inflation is addressed, namely the fact that some results are
in disagreement with nucleosynthesis constrains. A universal solution to this problem is found which leads to
reasonable reheating temperatures in all cases. It invokes the assumption that, immediately after inflation, the
moduli evolve like non-relativistic matter. The assumption is justified in the context of massive chaotic inflation
were, at the end of inflation, the universe evolves as if it was matter-dominated.
