Biological notes on two species of Eudemopsis Falkovitsh, 1962 (Lepidoptera: Tortricidae), with records of parasitoid natural enemies (Hymenoptera: Bethylidae, Braconidae, and Ichneumonidae)

Abstract

Five species of Eudemopsis Falkovitsh, 1962 (Lepidoptera: Tortricidae) have been recorded in Japan, but their biological data were insufficiently reported. This paper reports the larval biology of two Japanese species, E. toshimai Kawabe, 1974 and E. tokui Kawabe, 1974. Larvae of E. toshimai were discovered spinning young leaves of Actinodaphne acuminata (Lauraceae). Larvae of E. tokui in Hyogo Pref. were observed on the bent abaxial side of the leaf of Lindera glauca (Lauraceae) in the present study, while larvae in Yamanashi Pref. spun several young leaves of L. glauca as in the previous study. Larvae of E. tokui are parasitized by four species of Hymenoptera: Ascogaster bidentula Wesmael, 1835 (Braconidae: Cheloninae), Goniozus eriae Terayama, 2006 (Bethylidae: Bethylinae), Microplitis sp. (Braconidae: Microgastrinae), Phytodietus (P.) sp. (Ichneumonidae: Tryphoninae). These parasitoid wasps are reported for the first time as parasitoids of E. tokui.
