The adaptive significance of plasticity of digestive enzyme responses to
allelochemical stress was tested on 32 full-sib gypsy moth families from
an oak forest (the Quercus population) and 26 families from a
locust-tree forest (the Robinia population), reared on control or tannic
acid-supplemented diets. By using the relative growth rate as a fitness
measure in phenotypic selection analyses, we revealed that higher
specific activity of leucine aminopeptidase in Quercus larvae and lower
specific activity of trypsin in Robinia larvae were adaptive in the
control environment. In Quercus larvae, elevated specific activities of
leucine aminopeptidase and lipase were adaptive in the stressful
environment. There were no plasticity costs for the enzyme activities in
either experimental group. The obtained results suggest that adaptive
plasticity of digestive enzyme activity in gypsy moth larvae contributes
to optimal growth rate under various environmental conditions.
