Honeysuckle aphids, also known as Hyadaphis tataricae, are among the most troublesome insects that may infest the honeysuckle plant (Lonicera, hardy in USDA zones 4 to 9) These pests overwinter as eggs, and then they hatch the following spring. They are most often seen on young plant development. If you want to guarantee that your honeysuckle plants develop in a healthy manner, it is imperative that you take steps to control honeysuckle aphids.
What Are Honeysuckle Aphids?
Aphids that feed on honeysuckle are a nuisance that have a grayish-green tint. They have a black head and thorax, and their abdomens are white, and they are powdered with something that appears like a fine powder. According to the Pacific Northwest Insect Management Handbook, honeysuckle aphids may be distinguished from other types of aphids by the fact that their bodies are shaped more like manatees than pears. Honeysuckle aphids feed on honeysuckle flowers.
Aphids spend the winter as eggs on plants that have been afflicted by them, generally towards the tips of damaged branches and shoots. When there is new growth in the spring, the eggs hatch into aphids, which immediately begin feeding on the new growth. Aphids spend their whole lives only feeding on honeysuckle bushes because the flower clusters and curled leaves provide them security from other insects that may try to eat them. It’s possible that you’ll find their exoskeletons lying about.
Aphids cause harm to honeysuckle vines by feeding on the blooms and the leaves, which causes the leaves to become twisted and misshapen. These pests eat using mouthparts that are designed to suckle, and when they do so, they pump growth regulators into the plant. This is what causes the leaves to become misshapen. In addition to this, aphids leave behind a sticky residue, which increases the likelihood of ants invading the area. In addition to this, it creates an environment favourable for the growth of sooty mould, which will have further negative effects on your flowers.
Prevent Aphids on Plants
Even though it’s still early in the season, some gardeners decide to spray their plants with pesticide. Aphid egg clusters may be eliminated using insecticide, which will stop aphids from becoming a problem in the future. However, if the growth season is drawing to a conclusion, one of the quickest methods to avoid honeysuckle aphids is to kill all of the plants from the previous year that were afflicted with honeysuckle aphids, as well as any plant parts that were taken from the plant when it was pruned. Do not put them in the compost. Instead, you should burn them to ensure that every egg is annihilated.
Another strategy is to cultivate plants that are resistant to aphids. Aphids graze on a broad range of plant species, although individual species of aphids sometimes have a preference for feeding only on certain plant types. Aphids that feed on honeysuckle plants, for instance, are not likely to feed on bean plants, and vice versa.
However, there are certain plants that aphids find completely and utterly inedible. Consider cultivating aphid-deterrent plants in your garden, such as catnip (Nepeta cataria, which is hardy in zones 3-9), garlic (Allium sativum, which is hardy in zones 1-5), or chives (Allium schoenoprasum, hardy in zones 3-10). In the vicinity of attractive plants such as honeysuckle and roses, these may deter pests (Rosa, hardy in zones 4-9). In many instances, nasturtium (Tropaeolum majus, hardy in zones 4-8) might be helpful in warding off aphids. According to research conducted by Washington State University, these are not plants that deter aphids; rather, they are plants that attract aphids, which means that they will pull insects away from your honeysuckle vines and toward themselves.
The introduction of beneficial insects is a further measure that may be used to reduce the number of aphids on plants. Aphids on honeysuckle are consumed by a variety of predatory insects, including parasitic wasps (family Ichneumonidae), lacewings (order Neuroptera), and ladybugs (family Coccinellidae). It is possible to purchase populations of these insects online and then release them in your yard. Honeysuckle aphid populations should be kept at a low or perhaps nonexistent level as a result of this measure.
Treating Aphid Infestations
Spraying honeysuckle plants with soapy water is a common method that gardeners use to get rid of honeysuckle aphid infestations. It’s possible that this will get rid of some aphids, but it won’t solve the problem entirely.
Systemic insecticides are the only kind of treatment that are effective against a severe aphid infestation. According to research conducted at Kansas State University, acephate and imidacloprid are two of the most effective choices. It is best to apply them in the spring, when the first new leaves show, but before the newly born aphids have started feeding on the plant.
The application of the pesticide should destroy any eggs that are still there, and it should also protect the plant against aphids that may have already hatched and are hiding within the leaves. Because aphids develop many generations each year, it is possible that multiple treatments of pesticide will be required in some circumstances.
A dormant treatment is another use for horticultural oils that may be employed. This will result in a lower population of aphids that overwinter and will cause many eggs to suffocate. According to the University of Minnesota Extension, horticultural oil is not always as effective as an insecticide, and you need to be careful about when you apply it, because it can actually kill plants if it is applied during hot weather or the growing season.

The fact that this product originates from natural plant materials or, more rarely, from petroleum makes it less hazardous to the health of pollinators and other insects that are important to the environment. Because horticultural oil only repels insects when it comes into close touch with them and no longer has any effect after it has dried, you need to ensure that the whole area underneath the leaves is covered completely if you want to use it. Inspect your plants often throughout the growth season and take fast action if you see any symptoms of infection, regardless of the method you decide to use.
