摘要: . 1 The hypothesis that leaf-chewing caterpillars and leaf miners indirectly compete via the influence of foliar damage on parasitoids was experimentally tested using miner Coleophora serratella (L.) a complex folivorous birch. 2 Separate experiments effects manipulating artificial or caterpillar-induced parasitism at several spatial scales. 3 Parasitism C. by specialist generalist independent extent either collateral leaf-miner damage, whether naturally induced. 4 Support in literature for is restricted to single case, only limited scale; thus, idea directs parasitoid-mediated competition among herbivores remains highly speculative.
