Taxonomic Scheme of the 2014 Official National Science Olympiad Insect List is used in competition 30 Orders and 100 Families of Insects Identification, anatomy & physiology, reproduction, habitat characteristics, ecology, conservation, biogeography Process Skills: observation, inferences, data and diagram analysis Event Parameters: check 2014 rules for what is allowed Official National Insect List
the Official National Insect List is based upon the Audubon Guide to Insects and Spiders Since taxonomic schemes may vary greatly from source to source, the Science Olympiad Official Insect List will be used for all competitions and all arbitration questions will defer to the Audubon Guide to Insects and Spiders.

Texas A&M General Entomology https://insects.tamu.edu/students/undergrad/ ento201/lecture.html The Competition Specimens or images (nymph or larva for selected orders and families) will be exhibited usually as stations.
For any individual specimen, questions may also concern economic or health impact of specimens on humans. Topics may include structure and function of internal and external anatomy, ecology, behavior & history. One of the stations may involve using or formulating a simple dichotomous key to identify insects. Insect Taxonomy Kingdom Animalia Phylum Arthopoda Subphylum

Segmented body divided into three sections: head, thorax, abdomen Mouth including mandibles Three pairs of legs attached to the thorax One pair of antennae. External skeleton (exoskeleton) Usually, one or two pairs of wings attached to the thorax External
Anatomy Insect Eyes Mouth Parts Insect Wings Apterygota adults like immature without wings Pterygota adults have wings Exopterygota -the wings develop externally on the nymph body
Endopterygote wings develop inside of body in immature insects and not visible until adult immerges from pupa Metamorphosis Ametabolous Without Metamorphosis Young resembles the adult, except smaller Hemimetabolous-Incomplete Metamorphosis Egg, nymph, adult
Insects without metamorphosis The insect resembles the adult, except that it is smaller. Development involves increasing the insect's size by going through successive molts. Also Apterygota adult like immature without wings Hemimetabolous Incomplete
Metamorphosis Egg, nymph, adult Also Exopterygota winged insects, the wings develop externally on the nymph body Holometabolous Complete metamorphosis
Egg, larva, pupa, adult Also Endopterygote wings develop inside of body in immature insects and not visible until adult immerges from pupa Orders - Ametabola & Apterygote
Pollination of many flowering plants Decomposition of organic materials Recycling of carbon, nitrogen, and other essential nutrients Control of populations of harmful invertebrates including other insects Direct production of foods as honey Manufacture of products as silk Insect Pests 10,000 species

Study the information in the front of the field guide Become familiar with the organization of the color plates in the field guide Notice how the field guide organization is similar to the organization of the Official Insect List Put the page numbers of Orders and Families Information from the Audubon Guide to Insects and Spiders on the Official Insect List it will save you a lot of time Tab the field guide with very small useful tabs so it is not cluttered and can be easily used Practice using the Field Guide to identify specimens or photos Practice under timed conditions to prepare for competition Study Binder - Use It to Learn the Insects
The most effective resources are the ones produced by the students. The process of producing the resources is a major learning tool. Have a copy of the rules in your binder Have a copy of the lists (insects, birds, fossils if applicable) in your binder Prepare and organize materials by major topic divisions. Place materials from many different sources into your topic divisions Reduce the size of pictures where possible to get more information on a page. Color code information to help you locate or emphasize key items. Put pages in sheet protectors two per protector to save space. Use tabs to separate sections. Label tabs so items can be located with ease. Power Point Slides
Make power point slides for each species Make them so information can they can be used for practice Prepare them so they can be reorganized to make practice competitions for study Flash Cards
Make flash cards with pictures on one side and information on the back Use the flash cards to make up sample competitions Use the flash cards to learn the trees Actual Specimens
Collect and preserve insects Note that preserved specimens may not look exactly like live specimens texture and color changes may occur Use specimens to learn the insects Timer prepare practice stations and use the timer to improve efficiency of your teamwork skills Doing the Competition
Place information in appropriate place on answer sheet Print legibly so information is understandable Work as a team use time effectively Use Notes and Field Guide effectively Identify to Order and then to Family if needed Be sure to spell names correctly Carefully read all questions and use common sense in answering Relax, Do your best, and Have Fun!!
