spring and winter varieties, wide temperature tolerance and ability to grow under a variety of soil types and
rainfall patterns, give this crop a wide range of adaptability. One of the factors limiting wheat production
is attack by aphids. These cause damage by: extraction of plant sap; injection of toxic secretions;
transmission of viral diseases and excretion of honeydew. Particularly in cereals, honeydew reduces quality
by interfering in the milling process.]]>Al-Zubaidi, F.S. and J.L.
