Outline of Final Research Achievements

In a subsocial burrower bug, Adomerus triguttulus, whose females show parental care such as guarding and provisioning of food after oviposition, a phenomenon of “family combining”, whereby two families mix and the mothers provide food to the combined nymphs under natural conditions, was recently discovered. The present study examined whether “family combining” could progress toward the more developed social system, “quasisociality”, through field and laboratory studies to investigate the formation process and causal factors of family combining, as well as inter-familial interactions. The findings suggest that evolutionary transition to the more developed social system though “family combining” for this species would be difficult because a “cheating” female who abandons the provisioning task, leaving the other female to provision the entire brood of combined nymphs, and begins to prepare for her subsequent nest brooding will often arise when family combining occurs.
