| Research Abstract |
Wing size and flight muscle of ant-attended Tuberculatus aphids exhibited weak development than those of non ant-attended Tuberculatus aphids. Moreover, T quercicola exhibited reduced flight muscle development under ant attendance. These results suggested that ant-attended aphids have increased embryo numbers rather than flight in their course of evolution. In contrast, non ant-attended aphids have evolved flight behavior rather than increase in embryo numbers.
