      abstract     = {Caterpillars and spider mites are herbivores with different
                      feeding mechanisms. Spider mites feed on the cell content
                      via stylets, while caterpillars, as chewing herbivores,
                      remove larger amounts of photosynthetically active tissue.
                      We investigated local and systemic effects of short-term
                      caterpillar and spider mite herbivory on cotton in terms of
                      primary metabolism and growth processes. After short-term
                      caterpillar feeding, leaf growth and water content were
                      decreased in damaged leaves. The glutamate/glutamine ratio
                      increased and other free amino acids were also affected. In
                      contrast, mild spider mite infestation did not affect leaf
                      growth or amino acid composition, but led to an increase in
                      total nitrogen and sucrose concentrations. Both herbivores
                      induced locally increased dark respiration, suggesting an
                      increased mobilization of storage compounds potentially
                      available for synthesis of defensive substances, but did not
                      affect assimilation and transpiration. Systemically induced
                      leaves were not significantly affected by the treatments
                      performed in this study. The results show that cotton plants
                      do not compensate the loss of photosynthetic tissue with
                      higher photosynthetic efficiency of the remaining tissue.
                      However, early plant responses to different herbivores leave
                      their signature in primary metabolism, affecting leaf
                      growth. Changes in amino acid concentrations, total nitrogen
                      and sucrose content may affect subsequent herbivore
                      performance.},
