From the results, the ability of this species to utilize multiple host plants without strong innate preferences, combined with incomplete yet significant success in host switching during adulthood, likely promotes its invasive spread in Japan. Females were not attracted to their host-plant odors. The Ulmus population showed no significant differences in odor, feeding, or oviposition preferences. Both sexes of the Cercidiphyllum population had low feeding preferences for Ulmus, but showed no innate preference for the host plants. The Salix population was not attracted to Salix odor among those of the four host plants, but they fed more on Salix branches and showed oviposition preferences for Salix.

Sequencing of the cloned PCR products revealed the presence of both plant and fungal DNA. Second, we performed an amplicon analysis targeting ITS2 of plants and fungi using next-generation sequencing. A diverse array of fungi was detected; however, unexpectedly, no plant DNA was detected. The reason for this remains unclear; however, amplicon analysis appears to be biased toward the detection of fungi. Therefore, in the third experiment, we extracted DNA from individual spots on glass slides, amplified ITS1, and directly sequenced the PCR products.
