Caused By:-     Species of Hyadaphis aphids

There are two species of aphids, a sap sucking insect, from the Genus Hyadaphis that are the most troublesome pests of honeysuckle. These are H. tataricae a white/cream aphid and H. passerinii a grey/green aphid.
The toxins released by the aphids, during feeding, causes honeysuckle to grow in an abnormal way. The Leaves fold over which protect the aphid from predators and insecticides. In addition there is a shortening of growing tips and growth of dormant buds causing a witches-broom appearance. Eventually the affected tissue dies.
Often the damage caused throughout the season does not become apparent until winter, when the dead foliage and the unsightly witches brooms are more easily seen.
Red streaked, curled, and dwarfed leaves are typical of aphid damage. The aphids have several generations per season and later in the year adults can fly in to re-infest plants with eggs which overwinter mainly as eggs.
The degree of damage is dependent on the species of Honeysuckle that you are growing as some species or varieties are more resistant to the damage caused by the aphids. While attacks from the honeysuckle aphids do not kill the plant it will decrease its health and greatly reduce its aesthetic value.

Several things can be done to lessen attacks from this pest. In the winter you can spray with an horticultural oil which will suffocate many of the eggs and reduce the damage from any aphid attack.
Spraying with an insecticide is a two edge sword as you can easily kill the beneficial insects, like ladybirds and lacewings, that feed on the aphids. This will cause the aphid populations to come back with a vengeance. also spraying will have to be carried out several times a year as the aphids have several generations per year and can lead to the aphids becoming resistant to the insecticide.
Systemic insecticides are usually best as a knock down insecticide may not reach the aphids inside the curled up leaves. There is also less chance of systemic insecticides affecting beneficial insects.
Pruning out the infested branches and washing the aphids off with a good strong spray from the hose is a good option.
Growing species and cultivars of honeysuckle (Lonicera spp.) that are more resistant to the aphids.
Feed the plant with fertiliser and mulch if necessary to encourage strong healthy growth as this will usually prevent attack in the first place.
