Experimental design of the laboratory trials set to evaluate the feeding activity and performance of larvae of Triplectides gracilis exposed to leaves of Hoffmannia dusenii, Miconia chartacea, Eucalyptus globulus, Myrcia lineata, and Styrax pohlii.
Table 1.
Leaf chemistry and toughness values for the leaves of Hoffmannia dusenii, Miconia chartacea, Eucalyptus globulus, Myrcia lineata, and Styrax pohlii conditioned for 15 days in Macuco Stream.

Consumption rates (mean ± SE) of larvae of Triplectides gracilis exposed to leaves of Hoffmannia dusenii, Miconia chartacea, Eucalyptus globulus, Myrcia lineata, and Styrax pohlii in paired combinations. Each graphic (A–J) presents the results of one paired combination (treatment).
NC = Not consumed by larvae. Values with different superscript letters differed significantly. n = 30 (per treatment). Experiment duration = 10 days.

Consumption rates (black bars, mean ± SE) and production of fine particulate organic matter (white bars, mean ± SE) of larvae of Triplectides gracilis fed on leaves of Hoffmannia dusenii, Miconia chartacea, Eucalyptus globulus, Myrcia lineata, and Styrax pohlii in monodietary experiments.
n = 20 (per treatment). Experiment duration = five weeks.
