| Abstract: | Parasitoid assemblages and the rates of parasitism on tissue-feeding larvae of two Phyllonorycter leafminer species, P. persimilis and P. leucocorona, were studied from the autumn generation in 2002 to the summer generation in 2005 to understand whether parasitoids mediate interactions of the two leaf species. Fourteen species of parasitoids emerged from P. persimilis and 11 species emerged from P. leucocorona. The parasitism rate was high; i.e., 24.1-92.6% in P. persimilis and 58.9-81.7% in P. leucocorona. Thus, parasitism was a major mortality factor in the present Phyllonorycter species. The parasitoid composition was distinctly different between the two host species, although most parasitoids were able to parasitize both leafminer species. The analysis based on the quantitative parasitoid overlap revealed that the present parasitoids could mediate interactions between the present leafminer species, but their effects would be weak. This is attributable to that most parasitoids preferentially parasitize either of the leafminer species. |
