| Outline of Final Research Achievements |
It was found that induction in a tea leaf was induced by the oviposition of the smaller tea tortrix, Adoxophyes honmai, and the braconid parasitoid, Ascogaster reticulata, showed a searching behavior on the tea leaves. The elicitor, which is a factor causing the induction, adheres to the leaves by the host oviposition and has influence. The same effect was obtained by treating the abdominal homogenate of the host female moth to the abaxial side of the tea leaves. In addition, it was found that there was no elicitor activity in the male moth, and the elicitor was present in the unmated female, that there was no such activity in the non-host tortricid moth, Homona magananima. Furthermore, it was found that parasitoid avoid the leaf, when treating on a leaf the female abdominal homogenate of the corn borer, Ostrinia furnacalis, which is also nonhost.
