银纹盘蝶是日本的一种濒危草原蝴蝶。在这项研究中，我们重点研究了不同割草管理下的寄生蝇类的寄生率，以了解这种可能的自上而下的影响，而这种影响在很大程度上被忽视了。我们建立了三种不同的割草处理，割草强度不同，以植被高度表示。结果表明，棉铃虫对棉铃虫的寄生率较高。银色单胞菌随着植被高度的增加而增加，割草强度最高的地块的寄生率为8%，最低割草强度的地块的寄生率为42%。我们认为，澄清种间相互作用对于理解栖息地管理如何影响草原蝴蝶是很重要的。
Plebejus argyrognomonis an endangered grassland butterfly species in Japan. In this study we focused on the parasitism rate of tachinid flies under different mowing management to obtain knowledge of this possible top‐down effect that has been largely ignored. We established three mowing treatments differing in the intensity of mowing, as represented by vegetation height. The results showed that the parasitism rate ofP. argyrognomonincreased with vegetation height; the parasitism rate in blocks subjected to the highest mowing intensity was 8%, whereas in blocks subjected to the lowest mowing intensity, the rate was 42%. We suggest that clarifying interspecific interactions is important for understanding how habitat management affects grassland‐inhabiting butterflies in general.
