Abstract:
The green peach aphid,
Myzus persicae
is a polyphagous herbivore, attacking apiaceae
plants which are rich in defensive secondary metabo
lites. Thus,
M. persicae
owns a
protective antioxidative response to overcome the h
ost defense. The aim of the present
study was to investigate the adaptive antioxidative
response of
M. persicae
against the
secondary metabolites of cumin, anise, and coriande
r. The dietary antioxidants, ascorbic
acid and glutathione and enzymatic antioxidants, su
peroxide dismutase, catalase,
ascorbate peroxidase and glutathione peroxidase wit
hin tissues of
M. persicae
were
measured every two weeks during the infestation sea
son. The obtained results show that
Anise could be a good recommended host in the begin
ning of the infestation season
because it confers escalading levels of ascorbic ac
id. Coriander and cumin could be a
second choice. The variable levels of enzymatic ant
ioxidants during the season indicate
the adaptive responses of
M. persicae
against the plant defensive secondary metabolites.
