Outline of Final Research Achievements |
Examinations on the stable isotope revealed that the 4 super-colonies of Argentina ants in Japan have wide range of food habits, especially in the wide-distributed super colony, but have no correlation with their strength of aggressiveness. large numbers of Argentina ants were collected from Rhaphiolepis indica var. umbellate and Morella rubra as a provider of food and wintering nests. In contrary, the abundaces of the ants collected from the trees, Cinnamomum camphora and Juniperus chinensis cv. Pyramidalis and shrubs, Imperata cylindrica and Zoysia pacifica were significantly smaller than those of the other two wood and shrub species. These results suggested that creating of the green space by planting wood and shrub species that are hard to utilize by the invasive ants may also play a role in restraint efficacy against their invasion.
