| Outline of Final Research Achievements |
Tachinid flies are endoparasitoid of other insects and arthropods, and their larvae feed on the host body. We study information on hosts of the tachinid larvae with carbon and nitrogen isotope analysis for adults and In vitro experiment for larvae. In the isotope analysis, the data can roughly distinguish parasitoids from the other feeding habits such as saprophagy and organic decomposers. In particular, the saprophagous flies are usually very high in the nitrogen isotope ratio. However, there are individual and geographical variations in these isotope data and these variations grow with high trophic level. In the breeding experiments, isotope fractionation is confirmed to occur in insect metamorphosis and biological interactions. The interactions of this study are between plants (artificial diet)-phytophagous insects (hosts)- predator (parasitoids). Artificial medium with body fluid of host species (Mythimna separate) is developed for a tachinid species, Exorista japonica.
