taimeluseid

Taimeluseid, often translated as "plant lice" or "aphids," are small, soft-bodied insects belonging to the order Hemiptera and the superfamily Aphidoidea. They are characterized by their pear-shaped bodies, long antennae, and usually possess two cornicles, which are tube-like structures on their abdomen that excrete a defensive fluid. Taimeluseid exhibit complex life cycles, often involving both sexual and asexual reproduction, and can reproduce rapidly, leading to significant population growth. Many species are wingless, but winged forms are produced when populations become overcrowded or when dispersal to new host plants is necessary.

These insects are primarily plant feeders, using their piercing-sucking mouthparts to extract sap from various parts of plants, including leaves, stems, and roots. This feeding can cause damage to plants, leading to stunted growth, distorted leaves, and reduced crop yields. Taimeluseid are also known vectors for numerous plant viruses, which they transmit from infected to healthy plants while feeding. Their feeding also stimulates the production of honeydew, a sugary excretion that can attract other insects, such as ants, and promote the growth of sooty mold. They are found worldwide and infest a wide range of agricultural, horticultural, and wild plants.
