Summary: | The influence of allelochemical stress and population origin on the patterns
of phenotypic and genetic correlations among life history traits and
digestive enzyme activities were investigated in larvae of the gypsy moth
(Lymantria dispar L.; Lepidoptera: Lymantriidae). Thirty-two full-sib
families from oak (suitable host plant, Quercus population), and twenty-six
full-sib families from locust-tree (unsuitable host plant, Robinia
population) forests were reared on an artificial diet, with or without a 5%
tannic acid supplement. Comparison of correlation matrices revealed
significant similarity between the two populations in the structure of
phenotypic and genetic correlations of life history traits and of digestive
enzyme activities. The patterns of correlations of the examined traits,
within each of the two locally adapted populations and in the presence of
allelochemical stress, remained stabile despite the different selection
pressures that mold these traits. |
