| insect | 1. <zoology> One of the Insecta; especially, one of the Hexapoda. See Insecta. The hexapod insects pass through three stages during their growth, viz, the larva, pupa, and imago or adult, but in some of the orders the larva differs little from the imago, except in lacking wings, and the active pupa is very much like the larva, except in having rudiments of wings. In the higher orders, the larva is usually a grub, maggot, or caterpillar, totally unlike the adult, while the pupa is very different from both larva and imago and is inactive, taking no food. 2. <zoology> Any air-breathing arthropod, as a spider or scorpion. 3. <zoology> Any small crustacean. In a wider sense, the word is often loosely applied to various small invertebrates. 4. Any small, trivial, or contemptible person or thing. Insect powder,a powder used for the extermination of insects; especially, the powdered flowers of certain species of Pyrethrum, a genus now merged in Chrysanthemum. Synonym: Persian powder. Origin: F.insecte, L. Insectum, fr. Insectus, p.p. Of insecare to cut in. See Section. The name was originally given to certain small animals, whose bodies appear cut in, or almost divided. Cf. Entomology. Source: Websters Dictionary (01 Mar 1998) |

| insect defensins | <biochemistry> Family of small (30-35 residue) cysteine rich cationic proteins found in vertebrate phagocytes (notably the azurophil granules of neutrophils) and active against bacteria, fungi and enveloped viruses. May constitute up to 5% of the total protein. Insect defensins have some sequence homology with the vertebrate forms. (18 Nov 1997) |
| insect hormones | Hormones secreted by insects. They influence their growth and development. Also synthetic substances that act like insect hormones. (12 Dec 1998) |

| insect repellents | Substances causing insects to turn away from them or reject them as food. (12 Dec 1998) |
| insect stings | Stings from large stinging insects such as bees, hornets, yellow jackets and wasps can trigger allergic reactions varying greatly in severity. Avoidance and prompt treatment are essential. In selected cases, allergy injection therapy is highly effective. (the three a's of insect allergy are adrenaline, avoidance and allergist.)

| insecta | 1. <zoology> 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. See Insect. 2. <zoology> In a more restricted sense, the Hexapoda alone. See Hexapoda. 3. <zoology> In the most general sense, the Hexapoda, Myriapoda, and Arachnoidea, combined. The typical Insecta, or hexapod insects, are divided into several orders, viz., Hymenoptera, as the bees and ants; Diptera, as the common flies and gnats; Aphaniptera, or fleas; Lepidoptera, or moths and butterflies; Neuroptera, as the ant-lions and hellgamite; Coleoptera, or beetles; Hemiptera, as bugs, lice, aphids; Orthoptera, as grasshoppers and cockroaches; Pseudoneuroptera, as the dragon flies and termites; Euplexoptera, or earwings; Thysanura, as the springtails, podura, and lepisma.
