dc.description.abstract | We tested the hypothesis that C 4 grasses are inferior to C 3 grasses as host plants for herbivorous insects by measuring the relative performance of larvae of a graminivorous lepidopteran, Paratrytone melane (Hesperiidae), fed C 3 and C 4 grasses. Relative growth rates and final weights were higher in larvae fed a C 3 grass in Experiment I. However, in two additional experiments, relative growth rates and final weights were not significantly different in larvae fed C 3 and C 4 grasses. We examined two factors which are believed to cause C 4 grasses to be of lower nutritional value than C 3 grasses: foliar nutrient levels and nutrient digestibility. In general, foliar nutrient levels were higher in C 3 grasses. In Experiment I, protein and soluble carbohydrates were digested from a C 3 and a C 4 grass with equivalent efficiencies. Therefore, differences in larval performance are best explained by higher nutrient levels in the C 3 grass in this experiment. In Experiment II, soluble carbohydrates were digested with similar efficiencies from C 3 and C 4 grasses but protein was digested with greater efficiency from the C 3 grasses. We conclude (1) that the bundle sheath anatomy of C 4 grasses is not a barrier to soluble carbohydrate digestion and does not have a nutritionally significant effect on protein digestion and (2) that P. melane may consume C 4 grasses at compensatory rates. | en_US |
