The cotton aphid, for instance, has been found to transmit over 50 plant viruses.Īphids are known to reproduce faster than any other insect. Some species of aphids are also vectors of numerous plant diseases that are virus-related. This restricts photosynthesis which is the process through which plants manufacture essential sugars. When a plant is infested by sooty mold, the leaves become covered by a black coating which makes it difficult for sunlight to reach the leaf surface. This can lead to the growth of a fungus known as “sooty mold” on the plant.

Generally aphids feed in large groups or colonies. This allows the bugs to travel to other plants, reproduce, and start a new colony when food becomes scarce or the quality of food is decreased. While adult aphids are typically wingless, some species are able to mutate into a winged form when populations become too crowded in their colonies.
Some species of aphids also have two short tubes known as cornice projecting from their rears ends. The nymphs typically look identical to adults although they are much smaller in size. These bugs generally have pear-shaped bodies with long antennae projecting from the top of their heads. While most species of aphids are yellow in color, some may have a wide array of colors ranging from white, light green and pink to dark grey and black.
This can make it quite difficult to see single bugs with the naked eye. They are typically very tiny in size, with adult aphids measuring less than ⅛ inch in size.
