|---|---|
| Insects | Members of the phylum Arthropoda, subphylum Mandibulata, class Insecta |
| Arthropods | The creatures possessing a chitinous exoskeleton and jointed legs |
| Chitin | A hard but elastic body covering that envelops the entire body of all arthropods |
| Hemocoel | A body cavity filled with a bloodlike fluid |
| Hemolymph | Bloodlike fluid that bathes the internal organs of arthropods |
| Dioecious | Having separate sees, both male and female |
| Chelicerata | Subphylum of the arthropods that includes the mites, ticks, spiders, and scorpions that possess chelicerae mouthparts |
| Mandibulata | Subphylum of arthropods that possesses mandibulate mouthparts |
| Crustaceans | Members of the subphylum Mandibulatat, class Crustacea; members include the aquatic arthropods (crabs, lobsters, crayfish, and copepods) |
| How many sections is the body of adult insects divided into? | 3 - the head, thorax, and abdomen |
| Metamorphosis | To achieve the adult stage, and insect must undergo a series of developmental changes in size, form, and structure; the two types are simple metamorphosis and complex metamorphosis |
| Simple Metamorphosis | One of two types of metamorphosis by insects; 3 developmental stages are egg, nymph, and adult; nymphal and adult stages are similar in morphology and structure; nymphal stage is small than the adult and is not sexually mature |
| Complex Metamorphosis | One of two types of metamorphosis by insects; 4 developmental stages are egg, larva (maggot), pupa, and adult; each stage is morphologically and structurally different from the other stages |
| Dictyopterans | Members of the class Insecta, order Dictyoptera and include cockroaches and grasshoppers |
| Coleopterans | Members of the phylum Arthropoda, subphylum Mandibulate, class Insecta, order Coleoptera, and include beetles |
| Lepidopterans | Members of the class Insecta, order Lepidotera and include moths and butterflies |
| Hemipterans | Members of the class Insecta, order Hemiptera and include the true bugs |
| Hymenopterans | Members of the class Insecta, order Hymenoptera and include ants, bees, wasps, hello jackets, and other stinging insects |
| Anoplurans | Members of the class Insecta, order Anoplura and includes sucking lice |
| Mallophagans | Members of the class Insecta, order Mallophaga and include chewing lice |
| Siphonapterans | Members of the class Insecta, order Siphonaptera and include fleas |
| Acarines | Mites and ticks |
| Acariasis | Any infestation or infection by either mites or ticks |
| Capitulum | Mouthparts of an acarine (mite or tick) |
| Idiosoma | Abdomen of a mite or tick |
| Arthropodology | The study of arthropods |
| Myriopodans | Members of the phylum Arthropoda, subphylum Mandibulate, class Myriopoda and includes centipedes and millipedes |
| Cantharidin | Toxic or blistering compound found in a certain group of beetles; often referred to as Spanish Fly but has no aphrodisiac effect |
| Periodic Parasites | Parasites that make frequent short visits to their hosts to obtain nourishment or other benefits |
| Mucocutaneous | Pertaining to the mucous membrane and the skin |
| Nit | Egg of a sucking or chewing louse |
| Pediculosis | Infestation by either chewing or sucking lice |
| Myiasis | Infection or infestation of the tissues or organs of humans or domesticated or wild animals by larval members of the order Diptera |
| Hirsute | Very hairy |
| Palps | Appendages found near the mouth in invertebrate organisms that are used for sensation, locomotion, and/or feeding |
| Venation | Possessing veins in a part of the body |
| Setae | Tiny hairlike bristles found on Musca domestic and other arthropods |
| Synanthropic | Living with humans |
| Face Fly | A periodic parasite (genus Musca, species autumnalis) that feeds on mucus, tears, and saliva |
| Facultative Myiasis | Condition resulting from fly larvae, normally free living, that become parasitic and use a host for their development |
| Obligatory Myiasis | Lesions caused by fly larvae that require a vertebrate host for their development |
| Fly Strike | Lesion(s) produced in the tissues of vertebrae hosts by maggots or fly larvae |
| Spiracular Plate | Opening on the posterior end of some arthropod larvae used for breathing |
| Warbles/Wolves | Larvae of dipteran flies found in the skin of domestic or wild animals, producing cutaneous myiasis |
| Gadding | Action of a vertebrate host marked by running away from irritating flies |
| Siphonapterosis | Infestation with fleas |
| Flea Dirt | Partially digested blood defecated by fleas; also called flea feces and flea frass |
| Sarcoptic Acariasis (Scabies) | Infection caused by Sarcoptes mites |
| Demodicosis | Infection with the demodectic (Demodex) species of mites |
| Stylostome | Tube that forms in the host at the attachment site of chiggers |
| Palpi | Mouthparts |
| Empodia | Clawlike features on the end of the second pair of legs of Myobia musculi and Radfordia affinis |
| Chelicerae | Two cutting or lacerating organs of the capitulum |
| Hypostome | Penetrating, anchor like sucking organ of the tick |
| Pedipalps | Two legalize accessory appendages attached to the capitulum that act as sensory support |
| Scutum | Hard, chitinous plate that covers the body of some ticks |
| Inornate | Species of ticks with a reddish or mahogany color |
| Ornate | Species of ticks with distinctive white patterns on the dark reddish or mahogany background of the scutum |
