Cultural control of pests
involves management of the crop environment in such
a way as to reduce pest numbers or inhibit establishment
of pests. This could be achieved by removing
weeds which are hosts to pest insects, planting
crop borders with species which encourage beneficial
insects or by removing plant material which can
hold pests.
For example, a control
strategy in vineyards for the vine weevil, Orthorhinus
klugi, is
to remove and burn the canes after pruning. Larvae
of the weevil are stem borers and will be removed
from the vineyard, thereby breaking the life cycle
and reducing the population size.
