Privet aphid can cause leaf curling and distortion on privet hedges.
Privet aphid (Myzus ligustri) on Privet (Ligustrum)
Aphids, also known as greenfly and blackfly, are sap-sucking insects. The privet aphid is a small (1.5mm) greenish yellow aphid that only feeds on privet (Ligustrum).
Privet aphid is active during the spring and early summer, when its sap-feeding activities cause the leaves to yellow and curl. In severe attacks, the damaged leaves may dry up and drop off. Plants usually make a recovery later in the summer when the aphids are no longer active on the plant.
While the damage privet aphid causes can be unsightly, plants normally recover and may not be infested every year and so control is often unnecessary.
Aphids have many predaors, including ladybirds, hoverfly larvae, lacewing larvae and parasitic wasps. Unfortunately, out of doors, damaging aphid infestations often build up before the natural enemies are active in sufficient numbers to achieve control. Pest control products based on natural compounds or with a physical mode of action are less likely to have serious effect on natural predators.
