Phenotypic Plasticity, Epigenetic or Genetic Modifications in Relation to the Duration of Cd-Exposure within a Microevolution Time Range in the Beet Armyworm.

In the case of the pests inhabiting metal polluted or Training fields where the use of pesticides is common, a natural selection of resistant individuals can occur.This may pose serious problems for humans, agriculture, as well as the economies of many countries.In this study, the hypothesis that multigenerational (120 generations) exposure to cadm
