Currant-Sowthistle Aphids are sap-sucking bugs which feed on plants in dense colonies. Many aphids have complex life cycles, alternating between two species of plants throughout the life cycle. Hyperomyzus lactucae feed on Sowthistle during summer before migrating to Currant in the winter. Aphids can produce several overlapping generations each year, so numbers can multiply quick. Aphids can damage young foliage, resulting in leaves turning reddish-yellow, curling upwards at the tips.

Traits

These bugs cause leaves to discolour and curl upwards.
A food resource for predatory insects like ladybirds and their larvae!

Appearance

Adults: Aphids are transparent green with a central black patch. They have long black antennae and are around 5 mm. Wingless forms are also transparent green with long pale antennae. Nymphs: Look like wingless adults but are smaller and paler.

Symptoms

Foliage becomes puckered, becoming reddish/yellow at the tips of shoots. Honeydew and sooty mould on foliage. Tiny, pale green insects clustered near new growth. Galls, or abnormal growths, on inflorescence. Leaf discolouration. Rolled leaves. Stunted growth.

Biological treatment

By encouraging wildlife to visit your garden you can attract cheap and natural forms of biocontrol to keep pests at bay. These beneficial insects include ladybirds, lacewings, spiders and hoverfly larvae. Insect hotels are an excellent way to do this. Alternatively, you can provide spaces in your garden for beneficial wildlife to take cover by planting shrubs, trees, climbers or hanging baskets.

Chemical treatment

You can give plants a plant oil winter wash to eliminate any overwintering eggs. Best time to spray your plants is when insects are nymphs as they are more susceptible to sprays. Organic pesticides sprayed across several applications can be an effective way to control aphid nymphs.
