SCALE INSECTS Meaning and
Definition
-
Scale insects are a type of tiny insect belonging to the insect order Hemiptera and the superfamily Coccoidea. They are named for their protective scale-like covering, which shields their bodies during their feeding and development stages. This covering is often waxy, hard, and resembles a small, raised bump on the host plant.
These insects can range in size from less than 1 millimeter to several centimeters in diameter, depending on the species. They have mouthparts designed for piercing and sucking, allowing them to extract plant sap, which serves as their main source of nutrition. This feeding behavior often leads to detrimental effects on the infested plant, as it weakens the host and can impede its growth and development.
Scale insects are renowned for their ability to reproduce rapidly. The females lay eggs under their protective covering, which hatch into tiny nymphs that resemble the adults in shape and color. As they develop, scale insects may transition through several stages known as instars, during which they molt and grow until reaching maturity.
While some scale insects have the ability to move and spread to different parts of the plant, others remain relatively immobile throughout their lives. They are prevalent in various habitats worldwide and can infest a wide range of host plants, including trees, shrubs, and even some herbaceous species. Certain species of scale insects have symbiotic relationships with ants, which may protect and even transport them to new feeding sites.
Controlling scale insects usually involves a combination of physical, chemical, and biological measures. Integrated pest management (IPM) strategies are commonly employed to manage infestations, promoting long-term plant health while minimizing the use of harmful chemicals.

Etymology of SCALE INSECTS
The word "Scale Insects" combines two components, "scale" and "insects".
The term "scale" refers to the protective covering or shell-like structure that is characteristic of these insects. This scale is formed by the secretions of the insect itself, usually made of wax or a hard, chitinous material. The term "scale" originates from the Old Norse word "skáll" which means "bowl" or "scale".
The term "insects" comes from the Latin word "insectum", which means "cut into sections" or "divided body". This word was derived from the past participle of "insecare", which means "to cut into", referring to the segmented and divided body structure typical of insects.
Therefore, "Scale Insects" describes a group of insects that possess a protective scale-like covering on their bodies.
