| Outline of Final Research Achievements |
Certain plants have a mutualistic association with ants and are generally well-protected from herbivore attacks by the guardian ant. However, larvae of Oakblue butterflies on Macaranga ant-plants and a cockroach on epiphytic fern ant-plants survive and develop without being attacked by the ants living on the plant (known as plant-ant species). Chemical analyses of cuticular hydrocarbons (chemicals that play an important role in ant communication) and behavioral experiments revealed that although the responses of the plant-ants to the myrmecophiles varied considerably depending on the insect species, attacks by plant-ant species on the normal plant host were infrequent. Chemically speaking, however, A. dajagaka matched well the host plant-ants, A. amphimuta did not match, and unexpectedly, A. zylda lacked hydrocarbons.The cockroach, even more surprising, imposed its own chemical profile to the ants. Chemical strategy of myrmecophiles may be far more diverse than previously. thought.
