A multilateral approach that includes both biotic and climatic data was developed
to detect the main variables that affect the ecology and population dynamics of
woolly apple aphid Eriosoma lanigerum (Hausmann). Crawlers migrated up and
down the trunk mainly from spring to autumn and horizontal migration through the
canopy was observed from May to August. Winter temperatures did not kill the
canopy colonies, and both canopy and root colonies are the source of reinfestations in
Mediterranean areas. Thus, control measures should simultaneously address roots
and canopy. European earwigs Forficula auricularia (Linnaeus) were found to reduce
the survival of overwintering canopy colonies up to June, and this can allow their
later control by the parasitoid Aphelinus mali (Haldeman) from summer to fall.
Preliminary models to predict canopy infestations were developed. |
