1. Insect bad guys! You’ll never look at a bug the same.

2. Anatomy 3 pairs=6 legs 3 Body parts

3. Life Cycle-Insect Metamorphosis Complete –Egg –Larva (worms/catepillars) –Pupa (relatively dormnant) –Adult (flies, beetles, etc.) Incomplete –Egg –Nymph early-no wings Late-wings developing –Adult

4. *Insects must be killed when they are actively feeding or moving on the plant.

5. Complete Metamorphosis

6. Incomplete Metamorphosis

7. Damage Damage depends on the type of mouthpart Chewing-tear, chew or grind food Sucking: –Piercing: punctures plant and suck sap –Rasping: rasps or break surface and suck sap.

8. Damage Siphoning: have a coiled tube they dip into liquid food such as nectar and draw it in (ex. Butterfly) Sponging: have two sponge-like structures that collect liquid food and move it into the food canal. (ex. House fly)

17. Chewing- Grasshoppers Eat all parts of plants

19. Chewing- Bagworm Attack during larvae stage Leave brown spots on upper epidermis Eat entire leaves on older plants

20. Bagworm

21. Sucking Puncturing the surface to take out the sap of a plant or other animal. Controlled by systemic control

23. Sucking- Aphids Pierce and suck juices Plant lice Cause stunted growth, yellow spotted leaves Sticky substance and black mold Attracts ants

24. Aphids

25. Sucking- Leaf Bugs Causes plants to look unhealthy Lose normal color and wilt

26. Sucking- Mealy Bugs Pierce and suck from underside of leaves Suck in leaf axils Causes yellow appearance Sticky secretions

27. Mealy bug

28. Sucking- Thrips Chews and then sucks Causes plant tissue to become speckled or whitened Leaf tip withers Leaf curls and dies

29. Thrips

30. Sucking- Whiteflies Feeds on underside of young leaves Little flying white specks when plants are shaken

31. White flies

32. Sucking- Lace Bug Suck on underneath side but damage is noticed on upper part of the leaf as large yellow spots

33. Lace Bug

34. Sucking-Scale Suck juices from stems and other parts of the plant Cause plant as a whole to look unhealthy and stop growing Secretes honeydew that attracts the fungus, sooty mold Mealy bugs are a type of scale

35. Scale

36. Sucking- Mites (Watch Out it isn’t an insect) Attack underside of leaf Causes leaves to turn gray to grayish Severe infestations cause webbing Insects can be red Controlled by a miticide
