Reality and illusion on ecological risks of invasive Argentine ants

阿根廷蚂蚁对当地动物的影响进行了调查，除了蚂蚁在和周围的Hatukaichi-si，广岛县。阿根廷蚂蚁对地面节肢动物的影响不明显，但在入侵区，日本蜥蜴的密度降低。在阿根廷蚁入侵区，管巢蜂在蚂蚁觅食枝上的巢密度低于在蚂蚁隔离枝上的巢密度。阿根廷蚂蚁的入侵显著影响了亲蚁宿主动物。

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.
