Blackfly and greenfly (aphids) are very common sap sucking pests affecting nearly all types of plants. Colonies are visible around new buds or shoots in spring onwards. Leaves may twist or yellow and become puckered and distorted as they develop. Sticky honeydew can cause subsequent growth of black Sooty Mould, especially under damp conditions. Specific species of Aphids can be found on specific host plants. Some plant viruses, especially of Strawberry and raspberries, cucumbers can be spread via mouth parts of aphids as they move from plant to plant.
