• Mottled arum aphid

  colonies of mottled arum aphids can greatly reduce plant vigour and kill the plant through sucking of plant sap. However, also at lower densities the aphids [...] damage plants because they produce large amounts of honeydew, which provides an excellent substrate for the growth of black sooty mould. Large areas of mould [...] continuously producing new generations of females. There is no sexual stage in the life cycle. Wingless females of the mottled arum aphid are shiny whitish

On the leaves of sweet pepper, for instance [...] a later stage, the empty cells become desiccated and the adjacent cells turn brown. The vigour of the plant is also reduced by loss of chlorophyll. With [...] hatching, the larvae begin to feed on plant tissue on the underside of the leaf. The larvae are smaller than the adults and lack wings. Depending on the species
