1. Welcome to the World of Insects Original by Grant Lambdin Modified by Georgia Agriculture Education Curriculum Office –November 2005

2. Why should insects be included in our class? Insects are often mentioned in your daily school routine: -- busy as a “bee” -- don’t “bug” me -- mad as a “hornet” -- don’t be a “bookworm”

3. What is agriculture? Agriculture is more than just Chickens Cows Hogs Crops

4. What is agriculture? • the science or art of cultivating • the soil, producing crops,and • raising livestock and in varying • degrees the preparation of these • products for man’s use • and their disposal (as in marketing) • Webster’s Dictionary

5. What is agriculture? • Traditional Agriculture • Natural Resources • Environment/Biodiversity 1 2 3

6. What is one thing that all humans on Earth have in common? • They must eat!

7. EARTH COMPOSITION About 3% of all of the Earth’s surface is currently cropped to support ca. 6.4 billion people!!

8. Agriculture will continue to be important because we have to EAT! • Insects will continue to be • important to us as • beneficials and pests!

9. Importance of Insects to Agriculture PESTS – eat our foods - damage our crops 4 • spread plant, human, and animal diseases 5

10. Importance of Insects to Agriculture PESTS • infest our homes • infest our animals and our bodies 6 • sting us (venomous) 8 7

11. Importance of Insects to Agriculture PESTS - annoy us - cause unsightly damage 9 10

12. Importance of insects to Agriculture BENEFITS 11 – pollinate our plants - degrade and recycle nutrients

13. Importance of Insects to Agriculture BENEFITS - feed on pest species 12 - food for other animals

14. Importance of insects to Agriculture BENEFITS • used in research and medicine • provide natural products (e.g., honey, beeswax, • silk, dye, and • shellac) 13 14

15. MOST OF US RECOGNIZE BEETLES AS MAJOR PESTS!! DID YOU KNOW THATSOME PEOPLE “TREASURE”THEM AS COLLECTIBLES??

17. Let the METAMORPHOSIS begin!!

18. How many insects are there in the world? - about one million insect species have been described - scientists estimate that there may be as many as 10 million different types of insects!! - there are about 200 million insects for every human on earth!!

19. How many insects are there in the world? • insects comprise about • 10% of the earth’s weight • insects represent about • 80 to 85% of all life on earth WOW

20. PEST FACT The insect population of the world is at least 1,000,000,000,000,000,000 . Averaging the weight of each insect as 2.5 mg, the weight of the earth's insect population exceeds that of a factor of 12. human inhabitants by

21. Fortunately, most of these insects cause us no harm - only about 10% of all insects cause us the greatest amount of pain, anguish, and economic loss - because each one of you will come into contact with many types of organisms, it is important to properly identify them to effectively manage them

30. What makes an organism an INSECT?? [generally speaking] - three body parts [head, thorax, and abdomen] - six legs - one pair of antennae - one pair of compound eyes - an exoskeleton - most adult insects have wings

32. INSECTS are experts at two biological functions: 1) eating 2) reproducing [unfortunately, they do both of them extremely well!]

33. How can we separate or classify INSECTS?? 1) by the use of a written key [generally uses body parts] 2) by the type of damage that they cause [e.g., borer, gall former, leaf feeder] 3) by the type of mouthparts that they have or their manner of feeding [e.g., chewing or piercing-sucking]

34. These types of classifications help us to quickly place a “general label” on the “problem” insect!!

35. Types of Mouthparts [piercing-sucking] 24

36. Types of Mouthparts [chewing]

37. Types of wings and venation of wings 28

38. Types of development

43. CAN YOU MATCH THESE PHYSICAL WONDERS? • Run 50 body lengths in 1 second • (cockroach) • = a six-foot person running • ca. 206 miles per hour

44. CAN YOU MATCH THESE PHYSICAL WONDERS? • Run 50 body lengths in 1 second • (cockroach) 2) Flap your arms (“wings”) 300 times in 1 second (flying mosquito) • = about one million times • per hour

45. CAN YOU MATCH THESE PHYSICAL WONDERS? • Run 50 body lengths in 1 second • (cockroach) 2) Flap your arms (“wings”) 300 times in 1 second (flying mosquito) 3) Jump 130 times your height (flea) • = a six-foot person jumping • 780 feet

46. CAN YOU MATCH THESE PHYSICAL WONDERS? • Run 50 body lengths in 1 second • (cockroach) 2) Flap your arms (“wings”) 300 times in 1 second (flying mosquito) 3) Jump 130 times your height (flea) 4) Lift 10-50 times your weight (ant) • = a 200 lb person lifting • one to five tons!

47. CAN YOU MATCH THESE PHYSICAL WONDERS? • Run 50 body lengths in 1 second • (cockroach) 2) Flap your arms (“wings”) 300 times in 1 second (flying mosquito) 3) Jump 130 times your height (flea) 4) Lift 10-50 times your weight (ant) 5) Hear with your legs (cricket)

48. INSECTS THEY ARE EVERYWHERE!! • in the air 2) in the water 3) in the soil 4) in our homes 5) on our plants 6) on our animals 7) on our bodies!!

49. WELCOME TO THE WORLD OF INSECTS THE GOOD, THE BAD, AND THE BUGLY!
