disinsectization, disinsection
1. The removal of insects (as from an aircraft).
2. Spraying aircraft for insects, a procedure called disinsection.
3. Freeing any area from insects.

Some countries in Africa, Latin America, the Caribbean, Australia, and the South Pacific require the spraying of aircraft passenger compartments with insecticide while passengers are present. This is done to prevent the importation of insects; such as, mosquitos.

Disinsection procedures have been determined to be safe by the World Health Organization (WHO); however, they may aggravate allergies for some passengers.

1. A surgical procedure that involves an electrosurgical incision; such as, with a cautery.
2. An incision created by electrosurgery, ideally by using a fully rectified, alternating high-frequency current and producing minimal cellular injury.
3. Tissue division of the body with a knife-like electrode operated by a high-frequency device.
4. A type of electrosurgery used to cut into, to plane, or to remove tissue.

The active electrode uses slightly damped, modulated undamped, or undamped currents and may be a knife blade, wire loop, or needle; the passive electrode is an adhesive dispersive pad.

Insecta, insectan
One of the classes of Arthropoda, including those that have one pair of antennae, three pairs of mouth organs, and breathe air by means of tracheae, opening by spiracles along the sides of the body. In this sense it includes the Hexapoda, or six-legged insects and the Myriapoda, with numerous legs.

Some are parasitic, others serve as intermediate hosts for parasites, including those that cause many human diseases. Some are wingless; others, such as, the Diptera, have only one pair of wings.

Respiration is by tracheoles, cuticle-lined air tubes that pass air directly to the tissues. Development in higher forms is holometabolous and passes through distinctive egg, larval, pupal, and adult stages.

insectarian, insectarianism
Anyone who feeds on insects.
insectarium (s) (noun), insectaria, insectariums (pl)
A place for keeping a collection of living insects and for breeding them for scientific studies: "The local zoo had a special insectarium for visitors to visit."
insectary (s); insectaria, insectaries (pl)
A laboratory for the study of live insects, their life histories, effects on plants, reactions to insecticides, etc.
Pertaining to, having the nature of, or resembling, an insect.
Capable of killing insects or controlling their growth.
insecticide, insecticides
1. One who or that which kills insects, an insect-killer; specifically, a preparation used for destroying insects.
