You can go like

$("select[name='_users_id_requester'] option").not(":eq(1)").val('');

You can use some selectors to select precisely do what you want as the :nth-child and the :not one.

$("select[name='_users_id_requester']").find('option:not(:nth-child(2))').each(function(){
    $(this).attr("value", "");
});

The :nth-child selects a precise child and the :not do a sort array subtraction. It subtracts all the ones match by the not the with the whole array.

Here is a working JsFiddle. Just look at the HTML using Chrome or Firebug
