Abstract
Aphids are the major insect pests that attack wheat plants in Egypt. A study
was carried out in different agro-ecosystems (Upper-, Middle Egypt and Delta)
which represent the wheat regions in the country, aimed to maintain cereal
aphids' population at the economic threshold level based on: 1) evaluation of
the role of native natural enemies, mainly the parasitoids, 2) selection of
resistant and/or tolerant wheat cultivars to aphids' infestation, 3)
determination of economic threshold and injury levels, 4) evaluation of the
efficacy of some exotic parasitoid species under laboratory, field cages and
open fields, 5) evaluation of the effect of some cultural practices such as
variety, planting date and fertilization rates on infestation levels, 6)
monitoring immigration rates into the wheat fields using sticky traps, finally,
7) field application of all positive results to come out with recommendations
that could be transferred to the farmers to achieve reduction of pest
infestation rates in wheat fields by using pesticides, only when necessary.
