2. Objective 8.01 Discuss the anatomy and life cycle of pest.

3. What is an insect? Small animals that have three body regions and three pairs of legs equaling six legs Body regions –head –thorax –abdomen

4. Types of Insects The five types of mouthparts are important in identifying and controlling insects. –Chewing –Piercing –Rasping –Siphoning –Sponging

5. Chewing Insects Insects tear, chew or grind food Examples –grasshopper –beetle

6. Piercing Insects Punctures plant and sucks the sap

7. Rasping insect Rasps or breaks surface and sucks sap Example –thrips

8. Siphoning insects Have a coiled tube they dip into liquid food such as nectar and draw it in Example –butterfly

9. Sponging Insects Have two sponge-like structures that collect liquid food and move it into the food canal Example –housefly

10. Life Cycles Complete metamorphosis has four stages –egg –larva-worms or caterpillars –pupa –adult-flies, beetles, etc.

11. Life Cycles Incomplete metamorphosis has three stages –egg –nymph –Adult Insects must be killed when they are feeding or actively moving on the plant

12. Life Cycles

13. Chewing Insects Parts of leaves are eaten away –beetles –cutworms –caterpillars –grasshoppers

14. Chewing Insects Beetles –eat leaves, stems, flowers, fruit and nuts Cutworms –usually attack stems, but may eat other plant parts

15. Chewing Insects Caterpillars –larva of moths and butterflies –fuzzy or hairy –eat young leaves and stems –roll up in leaves making leaves curl Grasshoppers –eat all parts of plants

16. Sucking Insects Aphids Leaf bugs Mealy bugs Scale Thrips Whiteflies

17. Aphids Pierce and suck juices known as plant lice cause stunted growth and yellow spotted leaves causes sticky substances and black mold will attract ants

18. Aphids

19. Leaf Bugs Cause plants to look unhealthy plants will lose their normal color and wilt

20. Leaf Bugs

21. Mealy Bugs Pierce and suck from underside of leaves and in leaf axils causing yellow appearance and sticky secretions

22. Mealy bugs

23. Scale Appear as black or brown raised lumps attached to stems and underside of leaves causing yellow leaves and stunted growth

24. Scale

25. Thrips Chew and then suck causing plant tissue to become speckled or whitened, leaf tip to wither, curl up, or die

26. Thrips

27. Whiteflies Feed on underside of young leaves causing yellowing will look like flying little white specks when plants are shaken

28. Whiteflies

29. Mites Attack underside of leaves causing gray to grayish-green spots severe infestations cause webbing
