Abstract
The prevalence of nematode parasitism in mycophagous drosophilids was studied throughout their active season over 4 years (2000-2003) in Tomakomai Experimental Forest of Hokkaido University, northern Japan. In addition, effects of nematode parasitism on the feritility of drosophilid females were examined. A total of 18,177 adult drosophilid flies were collected from 43 fungal species found on the census route. The rate of nematode parasitism varied yearly, seasonally and among drosophilid species. Parasitized females carried much fewer eggs than unparasitized ones, revealing a strong deleterious effect of parasitism on the fitness of flies. The relative abundance of drosophilid species and the rate of parasitism were not significantly correlated, suggesting that nematode parasitism unlikely promoted the coexistence of drosophilid flies in this community.
