Insects and people
| Question | Answer |
|---|---|
| Approximately how many insect species have scientific names? | 900,000 |
| Fill in the blanks in the taxonomic hierarchy | Kingdom____, Phylum, _Class___, Order, _Family__, Genus, _Species, Subspecies (race) |
| In the scientific name Apis mellifera ligustica | . what taxonomic unit is designated by Apis? Genus b. what taxonomic unit is designated by mellifera? species c. what taxonomic unit is designated by ligustica? subspecies d. who is this insect? honey bee |
| What is meant by the term common name or vernacular name? | name in common parlance (indigenous language) EX. honey bee |
| What part of the name is the epithet? | The second part (species name) |
| What book did he write in 1758 | Systema Naturae |
| Give 3 good reasons for using scientific names instead of common names when talking about insects | a. universally understood b. convey taxonomic position c. contain info about organisms appearance d. applies to all life stages |
| What’s a patronym? | name of an organism honoring an individual who has contributed to the body of knowledge of that organism |
| True or false: Like species names, order names are always italicized | False |
| Names of which taxonomic units are always capitalized? | a. Class b. Order c. Family d. Genus |
| Where is the wax layer found? | epicuticle |
| What two insecticidal substances target the wax layer? | a. diatomaceous earth b. boric acid |
| Insect cuticle is made up of two major components, a carbohydrate polymer called | chitin |
| The chemical reaction that confers strength to the cuticle is called | cross-linking/tanning |
| Bursicon, first identified by UIUC Professor...is a hormone that initiatus the process of cuticle tanning (sclerotization) in insects. | Fraenkel |
| Describe two advantages of possessing an exoskeleton: | a. jointed legs and appendages b. economic use of limited amount of material |
| How does an exoskeleton make an open circulatory system possible? | cuticle isn’t leaky |
| What are the advantages of an open circulatory system? | greater tolerance of fluid loss. buffering capacity, room for storage, use of hydraulics for movements |
| List two ways in which jointed appendages improved insect locomotion | a. precise limb placement b. reduction of drag |
| List two ways jointed appendages can be used other than for locomotion: | a. sensory structure b. mouthparts c. sperm/egg transfer apparatus d. spinnerets from silk |
| In holometabolous development, adult tissues are quiescent throughout the immature stages in islands of adult cells called | imaginal discs |
| What is the one exception to the “Wings can never be molted”? | Mayflies (Ephemeroptera) |
| Explain the principal difference between endopterygotes and exopterygotes (as reflected in their names) | endo- wings develop internally, exo- wings develop externally |
| Ethology is: | the study of behavior in an environmental context |
| Provide an example of anthropomorphism | “killer” bees |
| sensilla | |
| Most peripheral sensory neurons are bipolar, with one end directed toward the environment and the other directed toward the | central nervous system |
| Name two places on moths and butterflies that are well-equipped with chemoreceptors: | antennae and tarsi (feet) |
| A single unit of a compound eye is | ommatidium |
| One of the simplest forms of behavior mediated by the nervous system is a reflex. Only 3 nerve cells are required: name them in the order in which they are activated: | a. mechanorecpter b. interneuron c. motor neuron |
| True or false: Learning is an adaptive change in behavior resulting from experience rather than from maturation. | True |
| tool use | insight learning |
| proboscis eversion in response to an acoustical signal | classical conditioning |
| cockroach nonresponsiveness to lights in an apartment | habituation |
| honey bee "house hunting | latent learning |
| List two advantages of acoustical communication over other forms of communication: | a. effective over great distances, b. works in the dark, c. species specificity |
| stridulation | from Latin, "make harsh sound--> crickets |
| The organ with which crickets hear is located on the | leg |
| The organ with which crickets hear is called | tympanum |
| Cricket boxing has been a popular sport in China dating back to | 200 BC |
| In the abdomen of adult fireflies is a light-producing organ. cells are called | photocytes |
| inside "lanterns" of fireflies contain a substance called | luciferin |
| Flashing is a result of inhibition of oxygen uptake by mitochondria by | NO |
| two biotechnological uses of the luciferase gene: | reporter gene and gene insertion |
