Mixed model for count data with overdispersion

Dear all,

I had quick search but it looks there is no simple way in lme4 or  nlme In
the case of overdispersion for count data,. How we can run mixed model for
count data with family of quasipoisson or maybe NB?

I my working on seeding emergence with 2 fixed factor (n=10) and i would
like to have my plot as replicate(n=5) as a random.

Warm regards,
Mehdi
