Thank you very much for this link. The implemented function "overdisp_fun" allowed me to get what I want. 
My data are indeed overdispersed and I think about adding an individual random effect, since quasi-binomial distribution are not supported by lmer. I may use 
penalized quasi likelihood, but I know that it is quite controverse. Maybe someone could give me some advice?
