Abstract.
Let 
be a sequence of integers. A primitive prime divisor of a term 
is a prime which divides but does not divide any of the previous terms of the sequence. A zero orbit of a polynomial 
is a sequence of integers 
where the n-th term is the n-th iterate of 
at 0. We consider primitive prime divisors of zero orbits of polynomials. In this note, we show that for 
in 
, where 
and 
, every iterate in the zero orbit of 
contains a primitive prime divisor whenever zero has an infinite orbit. If 
, then every iterate after the first contains a primitive prime divisor.
