| Research Abstract |
Effects of Argentine ants on native animals except for ants were investigated in and around Hatukaichi-si, Hirosima Prefecture. Effects of the Argentine ants on ground living arthropod animals were obscure, however, the density of a Japanese lizard was reduced in the invaded area. The nest density of tube nesting wasps in ant foraged branches was lower than that in ant excluded branches in argentine ant invaded area. Host specialist myrmecophilous animals are remarkably affected by the invasion of Argentine ants.
