Outline of Final Research Achievements

In some burrower bugs, females exhibit complicated parental care, including the provision of infertile trophic eggs and fruit of host plants. Gravid females sometimes suffered injuries, which had probably been attacked by predators. Such non-lethal predation may decrease their ability of fruit provisioning or residual reproductive value and thus may induce adaptive changes in trophic-egg production. To test the hypotheses, the compensation of decreased provisioning ability and the terminal investment, females were divided into three experimental groups: hind-leg removal, forewing removal and control groups. Females in the hind-leg removal group produced more trophic eggs per hatchling than those in the other two groups. The females also showed lower provisioning ability. These results strongly suggest that females that have lost legs compensate for decreased provisioning ability through increasing trophic-egg production.
