The number of aphids consumed has a great impact on larval development and survival and on adult size and fecundity Dabire, Aphid feeding on susceptible genotypes causes chlorosis and longitudinal streaking of leaves, and emerging leaves remain tightly rolled, which traps spikes and prevents diuraphiss normal development Mornhinweg, A more limited programme of introductions has been conducted in South Africa Tolmay and Prinsloo, Phytopathologia Mediterranea, 36 3: This aphid causes characteristic symptoms in cereals: The aphids feed from the phloem in the leaves.

While DNA methylation is present in most insects, it is only rarely observed among the holometabolous insect orders Coleoptera and Diptera, and is suspected to be undergoing evolutionary deletion in these orders [ 3940 ].
