Effects of the invasive Argentine ant, Linepithema humile (Mayr), on a myrmecophilous butterfly, Narathura bazalus (Hewiston), were investigated in the field in western Japan. Larvae of N. bazalus were attended by workers of Argentine ants in invaded parks and of ten native and one cosmopolitan ant species in uninvaded parks. The abundance of eggs and larvae were not significantly different between invaded and uninvaded parks. Pupal weight and parasitized ratio by tachinid flies were also not different between the two types of parks. These results indicate that the role of Argentine ants for the butterfly might be almost equivalent to the native ants.

阿根廷蚂蚁（膜翅目：蚁科）对日本西部嗜食蚁科蝴蝶（Narathura bazalus）（鳞翅目：蚁科）的影响

在日本西部的野外调查了入侵的阿根廷蚂蚁 Linepithema humile (Mayr) 对嗜食昆虫的蝴蝶 Narathura bazalus (Hewiston) 的影响。N. bazalus 的幼虫在被入侵的公园里有阿根廷蚂蚁的工人，在未入侵的公园里有 10 种本地蚂蚁和一种世界性蚂蚁物种。入侵和未入侵公园之间的卵和幼虫的丰度没有显着差异。两种公园之间的蛹重量和被 tachinid 苍蝇寄生的比率也没有差异。这些结果表明阿根廷蚂蚁对蝴蝶的作用可能几乎与本地蚂蚁相当。
