摘要
Research on invasive insects has long focused on the direct interactions such as predation or parasitism. This is partly because many weed control projects showed the unsuccessful establishment in herbivorous insects specializing invasive plants through native natural enemies. However, there is increasing appreciation of the importance of plant-mediated indirect effects in determining abundance of insect herbivores. We examined (1) how the lacebug, Corythucha marmorata, indirectly affects leaf consumption by the leaf beetle, Ophraella communa, on the ragweed, Ambrosia artemisiifolia, and (2) how the predacious lady beetle, Harmonia axyridis, influences the indirect interaction between both insect herbivores.
