Aphids are tiny insects equipped with a needle-like mouthpart that is used to pierce and suck the nutrients from plants. They are seen in a variety of different colors. Aphids are usually wingless but when overcrowding occurs, many species are able to develop wings in order to find another host plant.

Aphids exist in colonies and are usually found dwelling on the undersides of leaves and on plant stems. Population can increase quite rapidly because females, as young as six days old, are able to reproduce without mating. 

Damage

Aphids feed on the host plants, causing slow growth and wilting, curling and yellowing leaves. These insects may be difficult to detect because of their tiny size, so it may be easier to diagnose an aphid infestation by looking the sugary waste that they leave behind. If an aphid happens to absorb excessive amounts of a plant's sap, they excrete a sticky substance called 'honeydew'. Honeydew is clear and its sweetness may attract other pests, such as ants or bees. The stickiness of this substance may also lead to the growth of black sooty mold, which can be unsightly but virtually harmless to the health of the tree. Infestations are more likely to occur with warmer temperatures. 

Control

When treating an aphid problem with sprays or insecticides, be sure to treat the undersides of leaves and branches, where the aphids are often found dwelling. For minor infestations, a powerful jet of water may be helpful with managing the problem.
