Abstract
Effects of Certain Weather, Biotic Factors and Chemical Components on The population of Aphids in Egyptian Wheat Fields.
Highlights
Many pests attack the wheat plants result in great loss in goodness and proportion of the yield
Surveyed that wheat plants confirmed the presence of two aphid species, R. padi and S. graminum attacking the wheat plants R. padi was the dominant aphid species during the tested seasons (Mansour 2012)
We investigated the seasonal abundance of species aphid (Hemiptera: Aphididae): the green cereal bug aphid (Schizaphis gramium), the bird cherry-oat aphid (Rhopalosiphum padi), the corn leaf aphid (Rhopalosiphum maidis), and the english grain aphid (Sitobion avenea) and their predatory insects, Scymnus spp (ColeopteraCoccinellidae), the eleven spotted lady- beetle (Coccinella undecimpunctata), the green lacewing (Chrysoperla carnea), the rove beetle (Paederus alfierii), Syrphus fly (Syrphus corolla)
