No.

Looking at the code:

static int
snmp_resend_request(...)
{
    :

    rp->retries++;
    result = transport->f_send(...);

    :

    gettimeofday(&now, (struct timezone *) 0);
    tv = now;
    tv.tv_usec += rp->timeout;     <=====
    rp->expire = tv;
}


The same timeout value is added each time.
No back-off algorithm is applied.
