Aphids are small, soft-bodied insects that feed on plants by sucking sap from leaves, stems, and roots. They can cause significant damage to plants, leading to curled or distorted leaves, stunted growth, and reduced yields. Aphids can also transmit plant viruses and attract other pests, making them a major problem for gardeners and farmers. In addition, aphids can produce a sticky substance called honeydew, which can attract ants and wasps, and promote the growth of sooty mold.
