Crop intercropping and application of plant essential
oils in fields could obtain better effects in conserving and enhancing abundance of natural enemies, and simultaneously
reducing the cereal aphids damage in
agroecosystems. Alternative strategies can also avoid
environmental pollution and health problems caused by
the extensive use of traditional synthetic pesticides.
They are expected to contribute to the further improvement
of integrated pest management systems. Further
research needs to be done to evaluate the mechanisms
of how garlic and its volatiles affect natural enemies of
cereal aphids in a complex agroecosystem.
