Whiteflies are one of the major insect pests of greenhouse
production systems worldwide, feeding on a wide-range of
greenhouse-grown horticultural crops. Whiteflies cause both direct
damage by feeding on plant parts such as leaves as well as indirect
damage by vectoring certain plant viral and bacterial diseases. In
addition, since whiteflies feed within the phloem sieve tubes with
their piercing-sucking mouthparts, they may excrete honeydew, a
clear, sticky liquid that serves as a growing medium/food source
for certain black sooty mould fungi. This book examines the
biological control of whiteflies as well as aphids, which are
serious pests of agricultural crops, particularly in cereal crops
including winter wheat. Aphids induce stress to the wheat crop by
damaging plant foliage, lowering the greenness of plants, and
affecting productivity. Therefore, it is very important to monitor
and prevent effectively wheat aphid for crop management. Additional
chapters provide remote sensing data on aphid monitoring and
prediction; and changes in the distribution of Russian wheat aphid
biotypes in South Africa.
