“…Two species of non‐host pest insects, that is the Oriental tea tortrix, Homona magnanima Diakonoff (Lepidoptera: Tortricidae) and the Asian corn borer, Ostrinia furnacalis (Guenée) (Lepidoptera: Crambidae), were used for experimental treatments following the method of Piyasaengthong, Kinoshita, et al (). Homona magnanima is an economically important pest that often occurs together with A. honmai on tea plants in Japan, and O. furnacalis is the most serious insect pest of maize, Zea mays L., in many countries, including Japan and Thailand (Huang et al, ; Patanakamjorn, ). Thus, we tested whether A. reticulata females can discriminate changes on the adaxial surface of tea leaves after treatment with homogenized reproductive tissues of a non‐host insect ( H. magnanima or O. furnacalis ) compared with those on untreated leaf (control).…”

Ascogaster reticulata Watanabe (Hymenoptera: Braconidae) is an egg‐larval endoparasitoid of the smaller tea tortrix, Adoxophyes honmai Yasuda. Recent studies have examined tritrophic interactions among Camellia sinensis, A. honmai and A. reticulata, but the effect of non‐host insects on the induction of tea plant that may affect foraging behaviour of A. reticulata remains unclear. In this study, we selected two non‐host insects, Homona magnanima Diakonoff and Ostrinia furnacalis (Guenée), as representative species in our bioassays. Tea leaves were treated with homogenized female reproductive tissues of a non‐host insect in comparison with untreated leaves in a choice test. Residence times of parasitoids on both leaves were recorded. The parasitoids seemed to prefer walking on leaves treated with homogenates of H. magnanima over untreated leaves, but the difference in residence times was not significant. In contrast, its residence time on leaves treated with homogenates of O. furnacalis was significantly shorter than that on untreated leaves. Thus, the induction of tea leaf surface chemicals may differ among moth species, which may produce different types of elicitors. This difference may, in turn, affect the host‐searching behaviour of A. reticulata.
