Rapidly Induced Defenses and Talking Trees: The Devil's Advocate Position

摘要: We review the evidence that rapidly induced chemical changes in damaged leaves, for example, after attack by insects, (1) significantly influence population dynamics of herbivorous insects and mites field, (2) reduce damage to plants such herbivores. also "talking trees"; is, following experimental tree foliage, are adjacent undamaged trees mirror those trees. Most effects on is laboratory based, often reveals only small (< 10%) things as larval development time or pupal weights. Many reported larger statistically flawed. argue most responses may have negligible consequences field populations. There one study demonstrating significant defenses insect dynamics.
