leaf quality
The induction of tomato proteinase inhibitors, as a result of larval feeding, is invoked as a factor that systemically reduces leaf quality.
      
Mite age, population density, and host leaf quality affect various life history traits in spider mites.
      
Leaf quality experienced during deutonymph development had no effect on the behavior adults subsequently displayed.
      
It is recommended from this study that, in grouping different leaf materials as sources of N, the properties of soils into which they are incorporated should also be considered, in addition to leaf quality in terms of its chemical composition.
      
These results confirmed my hypothesis that the differences in leaf quality associated with the evergreen or deciduous life form would translate into food of differing quality for herbivores.
      
ilicicola does not render leaves more suitable for larvae, nor is it a means by which females sample leaf exudate to assess leaf quality prior to oviposition.
      
An influence of temperature and leaf quality on digestion rate and maintenance metabolism is the most likely cause of the feeding behavior pattern in G.
      
It is supposed that seasonal deterioration of leaf quality either masks the effects of induced defences or late-season species are better adapted to low-quality leaves.
      
In the third experiment we manipulated the apical dominance of shoots in ramets and caused improvement to leaf quality in extant shoots.
      
The results suggest that variation in leaf quality among and within plants is at least a partial explanation for ant selectivity and partial defoliation of preferred species.
      
We speculate that localized or systemic induction by both herbivores and pathogens can cause changes in leaf quality, effecting each other's subsequent colonization.
      
The effects of leaf quality on caterpillar performance are frequently investigated, as are the feeding preferences of caterpillars, but rarely are the two considered together to see how preferences match performance.
      
Nor is there a positive correlation with host leaf quality as measured by foliar nitrogen or by total or individual amino acid concentrations of host leaves.
      
Artificial damage induced only weak responses, and artificial canopy-wide damage even caused slight improvement of leaf quality.
      
(5) When confronted with unfamiliar leaves, on the other hand, they assessed leaf quality by probing bites at the leaf edge, although no actual cuts occurred.
      
Leaf quality and insect herbivory in model tropical plant communities after long-term exposure to elevated atmospheric CO2
      
Furthermore, no correlations were observed between these measures of leaf quality and leaf biomass consumption.
      
Changes in leaf quality are thus to be expected, irrespective of other plant responses to atmospheric CO2 enrichment.
      
Leaf phenology, seasonal changes in leaf quality and herbivory pattern of Sanguisorba tenuifolia at different altitudes
      
Leaf demography, seasonal changes in leaf quality and leaf-beetle herbivory of a herbaceous perennial plant, Sanguisorba tenuifolia, were compared between low- and high-elevation sites.
